5.1 The strip test in this test method is considered satisfactory for acceptance testing (that is, conformance to a specification) of commercial shipments of rolled erosion control products, since the method has been used extensively in the trade for acceptance testing.5.1.1 In case of disagreement arising from differences in reported test values when using this test method for acceptance testing of commercial shipments, the purchaser and the supplier should conduct comparative tests to determine if there is statistical bias between their laboratories. Competent statistical assistance is recommended for the investigation of bias. At a minimum, the two parties should take a group of test specimens which are as homogeneous as possible and are from a lot of material of the type in question. The test specimens should then be randomly assigned in equal numbers to each laboratory for testing. The average results from the two laboratories should be compared using Student's t-test for unpaired data and an acceptable probability level chosen by the two parties before testing is begun. If bias is found, either its cause must be found and corrected, or the purchaser and the supplier must agree to interpret future results in the light of the known bias.1.1 This test method covers strip test procedures for determining the tensile properties of rolled erosion control products (RECPs).1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information purposes only.1.3 This standard does not apply to RECPs made of composite materials where the component providing the reinforcement cannot be tested for tensile strength with the procedure herein described. In this case, the established ASTM testing method which is most appropriate for that material shall be used instead.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This specification deals with the hot-rolled, heavy thickness coils available for three designations: alloy steel, drawing steel, and structural alloy steel. Alloy steel is intended for general or miscellaneous use where bending and moderate forming is required. Drawing steel is used for severe cold plastic deformation such as deep drawn or severely formed parts. The material is available only in coils such as strip and sheet. As-rolled and annealed heat treatment shall be used for manufacturing the material. Drawing steel shall be furnished with a spheroidized annealed heat treatment unless otherwise specified. Heat analysis shall conform to the required grade specified for standard alloy steel, nonstandard alloy steel, and structural alloy steel. Grades shall conform to the required chemical composition for carbon, manganese, phosphorus, sulfur, silicon, copper, nickel, chromium, molybdenum, and vanadium. Mechanical tests for regular quality alloy steel and strip are not applicable; but for drawing steel and structural alloy steel, tension and hardness tests are required.1.1 This specification covers hot-rolled, heavy thickness coils beyond the size limits of Specifications A506 and A507.1.2 The product is available in three designations: Alloy Steel, Drawing Steel, and Structural Alloy Steel.1.3 Alloy steel is furnished to chemical composition requirements and is intended primarily for general or miscellaneous use where bending and moderate forming is a requirement.1.4 Drawing steel is produced principally for applications involving severe cold plastic deformation such as deep drawn or severely formed parts.1.4.1 Drawing steel may be furnished in several conditions, heat treatments, surface finishes, and edges, as specified herein.1.5 Structural steel is furnished to chemical composition requirements and to specific mechanical property requirements which may include tension tests, hardness tests, or other commonly accepted mechanical tests.1.5.1 The formability of structural steel decreases with increasing yield strength or hardness. Therefore, product design in relation to the mechanical properties of the grade used must be considered.1.6 This material is available only in coils described as follows:Product Size Limits, Coils OnlyWidth, in. [mm] Thickness, in. [mm]Strip Over 8 to 12, incl 0.230 to 1.000, incl  [Over 200 to 300] [Over 6.0 to 25]Sheet Over 12 0.230 to 1.000, incl  [Over 300] [from 6.0 through 25]1.7 Sheet and strip in coils of sizes noted in 1.6 are covered by this specification only with the following provisions:1.7.1 The material is not to be converted into steel plates for structural or pressure vessel use unless tested in complete accordance with the appropriate sections of Specifications A6/A6M (plates provided from coils) or A20/A20M (plates produced from coils). A plate produced in this manner is no longer governed by this sheet steel specification and since this material is now plate, the appropriate plate standard must now apply.1.7.2 The dimensional tolerances of Specification A635/A635M are applicable to material produced to this specification.1.7.3 The material is to be fed directly from coils into a blanking press, drawing or forming operation, tube mill, rolling mill, or sheared or slit into blanks for subsequent drawing or forming.1.8 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.TABLE 1 Standard Steels Commonly Produced for Alloy Steel Sheet and StripSteelDesignationNo. Chemical Composition Ranges and Limits, % (Heat Analysis)A  C Mn P S SiB Ni Cr Mo VE3310C 0.08-0.13 0.45-0.60 0.025 0.025 0.15-0.30 3.25-3.75 1.40-1.75 . . . . . .4012C 0.09-0.14 0.75-1.00 0.025 0.025 0.15-0.30 . . . . . . 0.15-0.25 . . .4118 0.18-0.23 0.70-0.90 0.025 0.025 0.15-0.30 . . . 0.40-0.60 0.08-0.15 . . .4130 0.28–0.33 0.40–0.60 0.025 0.025 0.15-0.30 . . . 0.80–1.10 015–0.25 . . .4135 0.33-0.38 0.70-0.90 0.025 0.025 0.15-0.30 . . . 0.80-1.10 0.15-0.25 . . .4137 0.35-0.40 0.70-0.90 0.025 0.025 0.15-0.30 . . . 0.80-1.10 0.15-0.25 . . .4140 0.38–0.43 0.75–1.00 0.025 0.025 0.15-0.30 . . . 0.80–1.10 0.15-0.25 . . .4142 0.40-0.45 0.75-1.00 0.025 0.025 0.15-0.30 . . . 0.80-1.10 0.15-0.25 . . .4145 0.43-0.48 0.75-1.00 0.025 0.025 0.15-0.30 . . . 0.80-1.10 0.15-0.25 . . .4147C 0.45-0.50 0.75-1.00 0.025 0.025 0.15-0.30 . . . 0.80-1.10 0.15-0.25 . . .4150 0.48-0.53 0.75-1.00 0.025 0.025 0.15-0.30 . . . 0.80-1.10 0.15-0.25 . . .4320 0.17-0.22 0.45-0.65 0.025 0.025 0.15-0.30 1.65-2.00 0.40-0.60 0.20-0.30 . . .4340 0.38–0.43 0.60–0.80 0.025 0.025 0.15-0.30 1.65-2.00 0.70–0.90 0.20-0.30 . . .E4340 0.38-0.43 0.65-0.85 0.025 0.025 0.15-0.30 1.65-2.00 0.70-0.90 0.20-0.30 . . .4520C 0.18-0.23 0.45-0.65 0.025 0.025 0.15-0.30 . . . . . . 0.45-0.60 . . .4615 0.13-0.18 0.45-0.65 0.025 0.025 0.15-0.30 1.65-2.00 . . . 0.20-0.30 . . .4620 0.17-0.22 0.45-0.65 0.025 0.025 0.15-0.30 1.65-2.00 . . . 0.20-0.30 . . .4718 0.16-0.21 0.70-0.90 0.025 0.025 0.15-0.30 0.90-1.20 0.35-0.55 0.30-0.40 . . .4815 0.13-0.18 0.40-0.60 0.025 0.025 0.15-0.30 3.25-3.75 . . . 0.20-0.30 . . .4820 0.18-0.23 0.50-0.70 0.025 0.025 0.15-0.30 3.25-3.75 . . . 0.20-0.30 . . .5015 0.12-0.17 0.30-0.50 0.025 0.025 0.15-0.30 . . . 0.30-0.50 . . . . . .5046 0.43-0.50 0.75-1.00 0.025 0.025 0.15-0.30 . . . 0.20-0.35 . . . . . .5115 0.13-0.18 0.70-0.90 0.025 0.025 0.15-0.30 . . . 0.70-0.90 . . . . . .5120 0.17–0.22 0.70–0.90 0.025 0.025 0.15-0.30 . . . 0.70–0.90 . . . . . .5130 0.28–0.33 0.70-0.90 0.025 0.025 0.15-0.30 . . . 0.80-1.10 . . . . . .5132 0.30–0.35 0.60-0.80 0.025 0.025 0.15-0.30 . . . 0.75-1.00 . . . . . .5140 0.38–0.43 0.70–0.90 0.025 0.025 0.15-0.30 . . . 0.70–0.90 . . . . . .5150 0.48–0.53 0.70–0.90 0.025 0.025 0.15-0.30 . . . 0.70–0.90 . . . . . .5160 0.56–0.64 0.75–1.00 0.025 0.025 0.15-0.30 . . . 0.70–0.90 . . . . . .E51100C 0.95–1.10 0.25-0.45 0.025 0.025 0.15-0.30 . . . 0.90-1.15 . . . . . .E52100 0.98–1.10 0.25-0.45 0.025 0.025 0.15-0.30 . . . 1.30-1.60 . . . . . .6150 0.48–0.53 0.70-0.90 0.025 0.025 0.15-0.30 . . . 0.80-1.10 . . . 0.15 min6158C 0.55–0.62 0.70–1.10 0.025 0.025 0.15-0.30 . . . 0.90–1.20 . . . 0.10–0.208615 0.13–0.18 0.70–0.90 0.025 0.025 0.15-0.30 0.40–0.70 0.40–0.60 0.15–0.25 . . .8617 0.15–0.20 0.70-0.90 0.025 0.025 0.15-0.30 0.40-0.70 0.40-0.60 0.15-0.25 . . .8620 0.18–0.23 0.70–0.90 0.035 0.035 0.15-0.30 0.40-0.70 0.40–0.60 0.15–.025 . . .8630 0.28–0.33 0.70-0.90 0.025 0.025 0.15-0.30 0.40-0.70 0.40-0.60 0.15-0.25 . . .8640 0.38–0.43 0.75-1.00 0.025 0.025 0.15-0.30 0.40-0.70 0.40-0.60 0.15-0.25 . . .8642C 0.40-0.45 0.75-1.00 0.025 0.025 0.15-0.30 0.40-0.70 0.40-0.60 0.15-0.25 . . .8645 0.43-0.48 0.75-1.00 0.025 0.025 0.15-0.30 0.40-0.70 0.40-0.60 0.15-0.25 . . .8650C 0.48-0.53 0.75-1.00 0.025 0.025 0.15-0.30 0.40-0.70 0.40-0.60 0.15-0.25 . . .8655 0.501-0.59 0.75-1.00 0.025 0.025 0.15-0.30 0.40-0.70 0.40-0.60 0.15-0.25 . . .8660 0.55-0.65 0.75-1.00 0.025 0.025 0.15-0.30 0.40-0.70 0.40-0.60 0.15-0.25 . . .8720 0.18-0.23 0.70-0.90 0.025 0.025 0.15-0.30 0.40-0.70 0.40-0.60 0.20-0.30 . . .8735C 0.33-0.38 0.75-1.00 0.025 0.025 0.15-0.30 0.40-0.70 0.40-0.60 0.20-0.30 . . .8740C 0.38-0.43 0.75-1.00 0.025 0.025 0.15-0.30 0.40-0.70 0.40-0.60 0.20-0.30 . . .9260 0.56-0.64 0.75-1.00 0.025 0.025 1.80-2.20 . . . . . . . . . . . .9262C 0.55-0.65 0.75-1.00 0.025 0.025 1.80-2.20 . .  0.25-0.40 . . . . . .E9310C 0.08-0.13 0.45-0.65 0.025 0.025 0.20-0.35 3.30-35.0 1.00-1.40 0.08-0.15 . . .(A) The chemical ranges and limits shown are subject to product analysis tolerances.

4.1 Materials Evaluation—Small single sheet testers were developed to supplement the testing of Epstein specimens for various applications. They are especially appropriate for determining the magnetic properties of samples when insufficient material is available for preparation of an Epstein specimen. Although the small specimen size is attractive, the precision of the small sheet testers is not expected to be as good as that of the test method Test Method A343/A343M. Small sheet testers are frequently used to measure the properties of both fully processed and semiprocessed nonoriented and magnetic lamination steels. Specimens of semiprocessed steels are normally subjected to an appropriate quality development anneal prior to testing. Small sheet testers may also be used to evaluate oriented electrical steels in either the as sheared or stress-relief annealed condition.1.1 This guide covers procedures for interpreting the specific core loss and peak permeability determined using small single-sheet test systems. It is limited to single-sheet test systems that require a test specimen or coupon be cut from the material being tested and are designed such that the entire width of that test specimen is magnetized during testing.1.2 This guide is primarily intended for measurements of the magnetic properties of flat-rolled electrical steels at frequencies of 50 Hz or 60 Hz under sinusoidal flux conditions.1.3 This guide includes procedures to provide correlation with the 25-cm Epstein test method (Test Method A343/A343M).1.4 The range of magnetic flux densities is governed by the properties of the test specimens and the instruments and test power source. Nonoriented electrical steels may be tested at magnetic flux densities up to about 16-kG [1.6T] for core loss. The maximum magnetic field strength for peak permeability testing is limited by the current carrying capacity of the magnetizing winding and the test power source. Single sheet testers are typically capable of testing at magnetic field strengths up to 50 Oe [4000 A/m] or more.1.5 Within this guide, a small single sheet tester (small SST) is defined as a magnetic tester designed to test flat, rectangular sheet-type specimens. Typical specimens for these testers are square (or nearly so). The design of the small SST test fixture may be small enough to accommodate specimens about 5 by 5 cm or may be large enough to accommodate specimens about 36 by 36 cm. Specimens for a particular SST must be appropriate for the particular test fixture.1.6 This guide covers two alternative test methods: Method 1 and Method 2.1.6.1 Method 1 is an extension of Method 1 of Test Method A804/A804M, which describes a test fixture having two windings that encircle the test specimen and two low-reluctance, low-core loss ferromagnetic yokes that serve as flux return paths. The dimensions of the test fixture for Method 1 are not fixed but rather may be designed and built for any nominal specimen dimension within the limits given in 1.5. The power loss in this case is determined by measuring the average value of the product of primary current and induced secondary voltage.1.6.2 Method 2 covers the use of a small single sheet tester, which employs a magnetizing winding, a magnetic flux sensing winding, and a magnetic field strength detector. The power loss in this case is determined by measuring the average value of the product of induced secondary voltage and magnetic field strength.1.6.3 The calibration method described in the annex of this guide applies to both test methods.1.7 The values and equations stated in customary (cgs-emu and inch-pound) or SI units are to be regarded separately as standard. Within this standard, SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with this standard.1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.9 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5.1 This index test method indicates a unvegetated RECP’s ability to reduce rainsplash-induced erosion under bench-scale conditions. This test method may also assist in identifying physical attributes of RECPs that contribute to their erosion-control performance.5.2 This test method is bench-scale and therefore, appropriate as an index test for initial indication of product performance, for general comparison of unvegetated RECP capabilities, and for product quality assurance/conformance testing. The results of this test are not indicative of an RECP’s actual field performance.NOTE 2: The quality of the result produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used. Agencies that meet the criteria of Practice D3740 are generally considered capable of competent and objective testing/sampling/inspections/etc. Users of this standard are cautioned that compliance with Practice D3740 does not itself assure reliable results. Reliable results depend on many factors; Practice D3740 provides a means of evaluating some of those factors.1.1 This index test method establishes the guidelines, requirements and procedures for evaluating the ability of unvegetated rolled erosion control products (RECPs) to protect soils from simulated rainfall (rain splash) and minimal runoff induced erosion. The critical element of this protection is the ability of the unvegetated RECP to absorb the impact force of raindrops, thereby reducing soil particle loosening through “splash” mechanisms, and limiting the ability of runoff to carry the loosened soil particles.1.2 This index test method utilizes bench-scale testing procedures and is not indicative of unvegetated RECP performance in conditions typically found in the field.NOTE 1: The values obtained with this bench scale procedure are for initial performance indication, general product comparison and conformance purposes only. These values should not be used in estimating RECP soil protection in actual field use with such calculations as the Universal Soil Loss Equation (USLE) or Revised Universal Soil Loss Equation (RUSLE) without verification from qualified, large-scale tests.1.3 This index test is not intended to replace full-scale simulation or field testing in acquisition of performance values that are required in the design of erosion control measures utilizing unvegetated RECPs.1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.1.5 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026, unless superseded by this standard.1.5.1 The procedures used to specify how data are collected/recorded or calculated in this standard are regarded as the industry standard. In addition, they are representative of the significant digits that generally should be retained. The procedures used do not consider material variation, purpose for obtaining the data, special purpose studies, or any considerations for the user’s objectives, and it is common practice to increase or reduce significant digits of reported data to be commensurate with these considerations. It is beyond the scope of this index test method to consider significant digits used in analytical methods for engineering design.1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use and may involve use of hazardous materials, equipment, and operations. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Also, the user must comply with prevalent regulatory codes, such as OSHA (Occupational Health and Safety Administration) guidelines, while using the index test method.1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5.1 Light penetration may be used to control the quality of many RECPs. Light penetration has not been proven to relate to field performance for all materials.5.2 The light penetration of RECPs may vary considerably, depending on the composite materials used in the matrix of the mat or due to inconsistency within a given mat. To minimize variation, specific sample size and procedures are indicated in this test method to help ensure comparable results.5.3 This test method may be used to determine the effect of different composite materials and makeup of RECPs on the penetration of light.5.4 This test method may be used for acceptance testing of commercial shipments of RECPs. Comparative tests as directed in 5.4.1 may be advisable.5.4.1 In case of a dispute arising from differences in reported test results when using this test method for acceptance testing of commercial shipments, the purchaser and the supplier should conduct comparative tests to determine if there is a statistical bias between their laboratories. Competent statistical assistance is recommended for the investigation of bias. At a minimum, the two parties should take a group of test specimens that are as homogeneous as possible and that are formed from a lot of material of the type in question. The test specimens should be randomly assigned in equal numbers to each laboratory for testing. The average results from the two laboratories should be compared using Student’s t-test for unpaired data and an acceptable probability level chosen by the two begun. If bias is found, either its cause must be corrected, or the purchaser and supplier must agree upon the known bias.NOTE 1: The light penetration has no definitive relationship to the amount of ground cover provided by a RECP, as the amount of light penetration may include light passing through translucent elements or light deflecting off of elements of the RECP structure. Thus, this test method is not intended to be used to determine a percent ground cover value for RECPs.NOTE 2: The user should be aware that the makeup and possible movement of the composite materials, and the like, may affect the RECPs following the time when they are rolled up on rolls, shipped, and stored.1.1 This test method covers measuring the amount of light that penetrates through a rolled erosion control product.1.2 This test method does not provide light penetration values for RECPs under variable normal sun and soil conditions. This test method determines nominal light penetration.1.3 This test method is not to be used to determine a percent ground cover value for RECPs, as the amount of light penetration may include light passing through translucent material or reflecting off surfaces.1.4 The values stated as a percentage are to be regarded as the standard. The values provided in footcandles are for information only.1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This specification covers the standard requirements for semi-processed cold-rolled magnetic lamination quality steels. These steels shall be made by the basic-oxygen or electric-furnace method and shall be processed by hot rolling, pickling, cold rolling, annealing, and temper rolling. Magnetic lamination steels shall have low-carbon contents and may have manganese, phosphorus, silicon, and aluminum additions to enhance punchability and to improve magnetic characteristics by increasing the electrical resistivity. There are no fixed chemical requirements for these steels only the requirement to meet the specified magnetic properties. These steels must be heat treated by the user to develop the specified magnetic properties. This specification covered steels with thicknesses of 0.0185 in. ( 0.47 mm), 0.022 in. (0.56 mm), 0.025 in. (0.64 mm), 0.028 in. (0.71 mm) and 0.031 in. (0.79 mm). For a given thickness there are three or more core loss types distinguished by maximum allowable core loss after a specified quality development anneal. Magnetic testing shall be done after the specified quality development anneal and shall use the Epstein test method. Magnetic testing shall be done at a test frequency of 60 Hz and a maximum flux density of 15 kG (1.5 T). Test methods to determine the magnetic and mechanical properties are listed. Other typical magnetic and physical properties are listed for reference. 1.1 This specification covers cold-rolled carbon sheet steel used for magnetic applications. These products, commonly called “cold-rolled magnetic lamination steel” (CRML) are usually intended for applications in which the stamped laminations or assembled core structures for electrical equipment are annealed to develop the desired core loss and permeability characteristics. 1.2 This steel is produced to maximum specific core-loss values and is intended primarily for commercial power frequency (50- and 60-Hz) applications in magnetic devices. Specific core-loss and permeability characteristics in conformance with this specification are developed through heat treatment by the user. 1.3 Non-guaranteed core-loss types, usually made to controlled chemical compositions, are available but are not covered by this specification. 1.4 Higher quality core-loss types are low carbon, silicon-iron, or silicon-aluminum-iron alloys containing up to about 2.5 % silicon and less than 1 % aluminum. These steels are usually given a critical reduction on a temper-mill to yield specified magnetic properties after a suitable lamination anneal. These products, typically called semiprocessed magnetic lamination steel, are classified by the ASTM Code Letter D in accordance with Practice A664. 1.5 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to customary (cgs-emu and inch-pound) units which are provided for information only and are not considered standard. 1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

[4.5 mm] to 0.230 in. exclusive [6.0 mm exclusive] over 48 in. [1200 mm] wide as that material is now covered by Specification A568/A568M – 06a. The purchaser is advised to discuss this change with the supplier.1.4 Sheet and strip in coils of sizes noted in 1.3 are covered by this specification only with the following provisions:1.4.1 The material is to be fed directly from coils into a blanking press, drawing or forming operation, tube mill, rolling mill, or sheared or slit into blanks for subsequent drawing or forming.1.4.2 The material is not to be converted into steel plates for structural or pressure vessel use unless tested in complete accordance with the appropriate sections of Specifications A6/A6M (plates provided from coils) or A20/A20M (plates produced from coils). Plate converted from coils is no longer governed by this sheet steel specification and since this material is now a plate, the requirements of the appropriate plate specification shall apply, except in cases where there is a conflict between the requirements of the plate specification and this specification. In these cases, the more restrictive limits of either specification shall apply.1.4.3 The dimensional tolerances of Specification A635/A635M are applicable to material produced to this specification.1.4.4 Not all strength levels are available in all thicknesses. The user should consult the producer for appropriate size limitations.1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This specification covers standards for high-strength, low-alloy, hot-rolled and cold-rolled steel sheets and strips cut in lengths or coils for structural and miscellaneous purposes. The material shall come in Types 2 and 4 steels having enhanced atmospheric corrosion resistance. The material shall follow specified carbon, manganese, and sulfur contents. Tension test shall be performed and material shall comply with tensile strength, yield strength, and elongation requirements. Edges and surface finish of the materials shall conform to specifications. Guidelines for retests are also given.1.1 This specification covers high-strength, low-alloy, cold-rolled sheet and strip in cut lengths or coils, hot-rolled sheet and strip steel in cut lengths or coils with ordered thickness less than 0.230 in. [6.0 mm], and hot-rolled sheet coils (not cut lengths) with ordered thickness 0.230 in. [6.0 mm] and thicker, intended for use in structural and miscellaneous purposes, where savings in weight or added durability are important. These steels have enhanced atmospheric corrosion resistance and are supplied in three types or as commercial steel (CS). Type 2 contains 0.20 % minimum copper based on cast or heat analysis (0.18 % minimum Cu for product check). Type 4 and Type 5 contain additional alloying elements and provide a level of corrosion resistance substantially better than that of carbon steels with or without copper addition (Note 1). When properly exposed to the atmosphere, Type 4 and Type 5 steels can be used in the bare (unpainted) condition for many applications. CS is intended for applications that require enhanced atmospheric corrosion resistance which do not require a specified strength. CS shall contain the chemical requirements of Type 2, Type 4, or Type 5. CS as contained within this specification is not associated with the requirements of CS that are referenced in other Subcommittee A01.19 on Steel Sheet and Strip specifications.NOTE 1: For methods of establishing the atmospheric corrosion resistance of low-alloy steels, see Guide G101.1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.1.3 Welding—In general, the steels listed in this specification are weldable with commonly obtained welding electrodes. When the steel is to be welded, a suitable welding procedure based on its composition should be used, taking into account intended use and service temperatures.NOTE 2: For a general discussion of the weldability of steel and carbon equivalents, consult Appendix X3 of A6/A6M.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
