This test method deals with the acceptance criteria for the magnetic particle examination of forged steel crankshafts and forgings having large main bearing journal or crankpin diameters. Covered here are three classes of forgings, which shall be evaluated under two areas of inspection, namely: major critical areas, and minor critical areas. During inspection, magnetic particle indications shall be classified as: surface indications, which include nonmetallic inclusions or stringers, open or twist cracks, flakes, or pipes; open or pinpoint indications; and non-open indications. Procedures for dimpling, depressing, inspection, and product marking are also mentioned.1.1 This is an acceptance specification for the magnetic particle inspection of forged steel crankshafts having main bearing journals or crankpins 4 in. [200 mm] or larger in diameter.1.2 There are three classes, with acceptance standards of increasing severity:1.2.1 Class 1.1.2.2 Class 2 (originally the sole acceptance standard of this specification).1.2.3 Class 3 (formerly covered in Supplementary Requirement S1 of Specification A456 – 64 (1970)).1.3 This specification is not intended to cover continuous grain flow crankshafts (see Specification A983/A983M); however, Specification A986/A986M may be used for this purpose.NOTE 1: Specification A668/A668M is a product specification which may be used for slab-forged crankshaft forgings that are usually twisted in order to set the crankpin angles, or for barrel forged crankshafts where the crankpins are machined in the appropriate configuration from a cylindrical forging.1.4 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.1.5 Unless the order specifies the applicable “M” specification designation, the material shall be furnished to the inch units.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.

5.1 The energy input rate test is used to confirm that the fryer under test is operating in accordance with its nameplate rating.5.2 Fryer temperature calibration is used to ensure that the fryer being tested is operating at the specified temperature. Temperature calibration also can be used to evaluate and calibrate the thermostat control dial.5.3 Preheat energy and time can be used by food service operators to manage their restaurants' energy demands, and to estimate the amount of time required for preheating a fryer.5.4 Idle energy rate and pilot energy rate can be used to estimate energy consumption during non-cooking periods.5.5 Preheat energy, idle energy rate, pilot energy rate, and heavy- and light-load cooking energy rates can be used to estimate the fryer's energy consumption in an actual food service operation.5.6 Cooking-energy efficiency is a direct measurement of fryer efficiency at different loading scenarios. This information can be used by food service operators in the selection of fryers, as well as for the management of a restaurant's energy demands.5.7 Production capacity is used by food service operators to choose a fryer that matches their food output requirements.1.1 This test method covers the energy consumption and cooking performance of large-vat open, deep fat fryers. The food service operator can use this evaluation to select a fryer and understand its energy efficiency and production capacity.1.2 This test method is applicable to Types 1 (counter), 2 (drop-in), 3 (floor-mounted, portable), and 4 (floor-mounted, stationary), size C, D, E and F, electric (Style A, B and C) and gas (Style D) open vat fryers as defined by Specification F1963, with nominal frying medium capacity greater than 50 lb (23 kg) or a vat size 18 in. or greater in width. For size A, B, and C and open vat fryers with a nominal frying medium capacity less than or equal to 50 lb (23 kg), or a vat size less than 18 in. in width, refer to Test Method F1361.1.3 The fryer can be evaluated with respect to the following (where applicable):1.3.1 Energy input rate (10.2),1.3.2 Preheat energy and time (10.4),1.3.3 Idle energy rate (10.5),1.3.4 Pilot energy rate (10.6, if applicable),1.3.5 French fry cooking energy rate and efficiency (10.8),1.3.6 French fry production capacity and frying medium temperature recovery time (10.8),1.4 This test method is not intended to answer all performance criteria in the evaluation and selection of a fryer, such as the significance of a high energy input design on maintenance of temperature within the cooking zone of the fryer.1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that 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.

4.1 Procedure A—This procedure is an index-type test which can be used as a guide for acceptance of commercial shipments of geosynthetics. The standard cone and pyramid test fixtures can establish critical height (ch) consistency with similar material from previous lots or different suppliers, as well as testing from other laboratories. However, due to the time required to perform tests, it is generally not recommended for routine acceptance testing.4.2 Procedures B and C—These procedures are performance tests intended as a design aid used to simulate the in-situ behavior of geosynthetics under hydrostatic compression. These test methods may assist a design engineer in comparing the ability of several candidate geosynthetic materials to conform to a site-specific subgrade under specified use and conditions. In procedure B, the pressure is increased until a failure is observed. In procedure C, a given set of conditions (pressure, temperature and test duration) are maintained constant and the performance of the system is observed at the end of the test.1.1 This test method evaluates the stress/time properties of geosynthetics by using hydrostatic pressure to compress the geosynthetic over synthetic or natural test bases consisting of manufactured test pyramids/cones, rocks, soil, or voids.1.2 This test method allows the user to determine the relative failure mode or points of failure for geosynthetics, or both.1.3 This test method offers two distinct procedures:1.3.1 Procedure A incorporates manufactured test pyramids or cones as the base of the testing apparatus. Procedure A is intended to create comparable data between laboratories, and can be used as a guide for routine acceptance tests for various materials.1.3.2 Procedures B and C incorporate site-specific soil or other material selected by the user as the test base of the testing apparatus. Procedures B and C are methods for geosynthetic design for a specific site.1.4 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.1.5 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. For a specific warning statement, see Section 6.1.6 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.

5.1 This test method does not establish requirements for airtightness but provides means of assessing compliance with specified air-leakage rates established elsewhere.5.2 This test method is used to determine the airtightness of building envelopes or portions thereof by measuring the air leakage rate at specified reference pressure differentials.5.3 This test method provides:5.3.1 Specific directions for determining acceptable weather conditions for conducting the test.5.3.2 Two different test boundary preparation conditions; building envelope (9.1.1.1), and operational envelope (9.1.1.2).5.3.3 Testing conducted in a range of pressures from 10 Pa (0.04 in. WC) to 100 Pa (0.40 in. WC).5.4 A measurement of the air-leakage rate of the constructed building envelope. Test methods that measure the air permeance of materials (Test Method E2178) and air leakage of assemblies (Test Method E2357) alone do not address the various complexities of the constructed building envelope, including but not limited to design, sequence, constructability, workmanship, and the transitions between assemblies.5.5 This test method applies to all multizone and large building types and portions or subsections of buildings. It can be used to test envelopes that consist of a single zone or subsections of a zone that can be tested as a single zone. Test envelopes that are entirely composed of subsections separated by interior partitions or floors, or both, may be tested as a single zone by maintaining baseline relationships between these subsections throughout testing. (See Appendix X1. See also Test Methods E779 and E1827.) Isolated subsections, each with its own specified air-leakage rate, shall be treated as separate test envelopes and tested separately. While testing isolated subsections, monitoring must be conducted for any extraneous/flanking air movement between the different zones.5.6 The building preparations prior to testing (fenestration positions and preparation of intentional openings such as HVAC penetrations and equipment) are critically important and can have a strong influence on the final test results. This test method includes guidance for testing of the building envelope both including and excluding HVAC-related openings.5.7 Compliance with a specified air leakage rate does not imply that all potentially problematic leaks have been sealed.5.8 While this test determines the air leakage rate of an envelope, it does not identify the location of leakage sites.NOTE 1: See, for example, Practices E1186 for locating leaks. The location of leaks, in addition to their cumulative leakage area, is also an important determinant of leakage under normal operating conditions.1.1 This standard test method provides a quantitative field-test procedure and calculation method for assessing an air leakage rate using a fan-induced pressure differential(s) across the building envelope, generated by blower doors or equivalent equipment.1.2 Building setup conditions in accordance with defining the test boundaries appropriate for testing the envelope’s air leakage are defined in this test method.1.3 Procedure to determine the air pressure boundaries of the test envelope to be tested are provided in this test method.1.4 This test method applies to all multizone and large building types and portions or subsections thereof.1.5 This test method defines three test procedures: multipoint regression, repeated single point, and repeated two-point air leakage rate testing.1.6 This test method allows for testing the test envelope in a pressurized condition, a depressurized condition, or in both conditions and averaging the results.1.7 This test method applies to an air leakage rate specification with a reference pressure greater than 10 Pa (0.04 in. WC) and not greater than 100 Pa (0.40 in. WC).1.8 This test method describes two methods of preparation for the building in order to conduct the test: the building envelope where HVAC-related openings are excluded, and on the operational envelope where the HVAC-related openings are included.1.9 Units—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.1.10 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.1.11 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.

6.1 Comparison with Other Inclusion Rating Methods—Because the test is performed on a volumetric rather than a surface-examination basis, the ultrasonic method is inherently better able to detect infrequently occurring large inclusions or clusters of small inclusions than eddy current, magnetic particle, microscopical, or macroscopic examination procedures.6.2 Limitation of Inclusion Size and Type—A limitation of the method is that it will not detect all inclusions. Inclusion chemistry, size, shape, location, and distribution may limit the ability of the method to provide indications distinct from those generated by the surrounding metallurgical structure. The recommended practice is only meaningfully applicable to examination of steel wherein the inclusion size and type are within the detection capabilities of the method. For steel wherein inclusion size, dispersion, and chemistry prevent optimum inclusion detection by ultrasonics, microscopical methods detailed in Test Methods E45 may be applied.1.1 This practice covers a procedure for the rating of rectangular steel sections by immersion ultrasonic techniques. Its purpose is to provide information on the content of large inclusions or clusters of small inclusions for determining the suitability of a steel lot for bearing applications. This practice in no manner defines or establishes limits of acceptability.1.2 For this document, large inclusions are defined in ultrasonic terms as those having a reflecting area equivalent to or larger than a 1/64 in. diameter flat-bottom hole in a steel reference block of similar properties and thickness. In metallographic terms, large inclusions, defined in this way, are of approximately the same size as the smallest detectable sizes revealed by the macroscopic methods of Test Methods E45. In some cases, inclusions smaller than those described previously can be detected either individually or in clusters, depending on their type, chemical composition, orientation to the ultrasonic beam and distance from the sound entry surface of the specimen.1.3 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.1.4 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.

3.1 This practice is useful for preparing coked specimens for subsequent testing where the shapes desired cannot be fitted into the coking box described in Test Methods C831.3.2 This practice can be very sensitive to heating rates in coking. Thus, strict adherence to the coking procedure is necessary.1.1 This practice covers the preparation of coking of carbon-bearing material for subsequent testing such as modulus of rupture, slag testing, thermal conductivity, and thermal expansion. Test Methods C831 is the specified method for testing residual carbon.1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.3 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 and health practices and determine the applicability of regulatory limitations prior to use.

ISO 8768 may not meet the requirements for Test Method G.1.1.4 Test Method H—Rolling Test—For determining the ability of complete, filled large shipping cases or crates to withstand the effects of rolling.NOTE 2: Test Method H fulfills the requirements of ISO 2876. ISO 2876 may not meet the requirements for Test Method H.1.2 Additional Test Procedures: 1.2.1 Test methods for mechanical handling of unitized loads and large shipping cases and crates are set forth in Test Method D6055. Additional tests that apply to mechanical handling of unitized loads and large cases and crates include incline impact tests, described in Test Method D880 and horizontal impact tests, described in Test Methods D4003 and Test Method D5277. Test Methods D4003 includes a special pallet marshaling test and Test Methods D1185 provides test methods for pallets and related structures.1.2.2 Practice D4169 provides a series of options for selecting and running performance tests on all types of shipping containers and systems.1.3 The values stated in inch-pound units are to be regarded as the standard. The SI units given in parentheses are for information only.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.
