4.1 The procedure for establishing the long-term pressure rating of fittings starts with an extrapolation of a regression line that is based on fitting failure data with respect to time, when assemblies are tested in accordance with Test Method D1598. The pressure-versus time to failure data are obtained using water at 73 °F in assemblies that are immersed in a water or air environment. The extrapolation is made in such a manner that the long-term hydrostatic pressure rating is determined for these conditions.4.2 The pressure design basis is determined by considering the following items and evaluating them in accordance with 6.3.4.2.1 Long-term hydrostatic pressure-strength at 100 000 h,4.2.2 Long-term hydrostatic pressure-strength at 50 years4.3 The fitting pressure rating may be calculated by multiplying the pressure design basis (PDB) by the appropriate design factor (DF).1.1 This test method covers a procedure for establishing Pressure Rating for PVC schedule 40 and 80 socket-type fittings by evaluating fitting failure test data derived by testing water-filled assemblies of pipe and fittings.1.2 Unless the data approximates a straight line, when calculated using log-log coordinates, it is not possible to assign a pressure rating to that product or sample of product. Data that exhibit high scatter, or a downward curve, due to low long term data, will give low extrapolated values that are more conservative when calculated using log-log co-ordinates. In addition, this downward curve will show as higher scatter, and where the lower confidence level limits are not met the data shall be classified as unsuitable. (See Note 1)NOTE 1: This test method is similar to that used in Test Method D2837, which has been used for about 30 years to establish the HDS of plastic pipe materials and is the basis for all pressure ratings assigned to plastic pipes.1.3 The products covered by this test method are schedule 40 or 80 molded PVC fittings that conform to Specifications D2466 or D2467.1.4 The pressure ratings developed using this test method applies only to fittings identical to the ones that were tested. Some variables that will affect the pressure rating are – pipe size, pattern, mold design, material, and molding conditions.1.5 The values in inch-pound units are to be regarded as the 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 The testing procedure used to obtain the fitting failure data shall be as described in those sections of Test Method D1598, that are referenced in Section 6 of this test method.1.7 The products covered by this test method are intended for use in the distribution of pressurized liquids at 73 °F. When appropriate, the design engineer must consider the effects of elevated temperature and chemical compatibility of the liquid with the fitting material and apply necessary design factors.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.NOTE 2: Pressurized (compressed) air or other compressed gases contain large amounts of stored energy which present serious safety hazards should a system fail for any reason.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.

ASTM E413-22 Classification for Rating Sound Insulation Active 发布日期 :  1970-01-01 实施日期 : 

4.1 These single-number ratings correlate in a general way with subjective impressions of sound transmission for speech, radio, television, and similar sources of noise in offices and buildings. This classification method is not appropriate for sound sources with spectra significantly different from those sources listed above. Such sources include machinery, industrial processes, bowling allies, power transformers, musical instruments, many music systems, and transportation noises such as motor vehicles, aircraft and trains. For these sources, accurate assessment of sound transmission requires a detailed analysis in frequency bands. A single-number sound transmission rating for building façade elements is given in Classification E1332.4.2 The single-number ratings obtained can be used to compare the potential sound insulation of partitions or floors tested in laboratory conditions (STC) or the actual sound isolation between different suites in buildings (NNIC, NIC). The rating for a partition built and tested in a building may be lower than that obtained for a partition tested in a laboratory because of flanking transmission or construction errors.NOTE 1: A similar rating procedure, described in ISO 717-1:2020, provides single figure sound insulation ratings with a frequency range that extends from 100 to 3150 Hz with no maximum deficiency specified at individual frequencies. For most partitions, the two ratings differ by only one or two points.1.1 This classification covers methods of calculating single-number acoustical ratings for laboratory and field measurements of sound attenuation obtained in one-third octave bands.1.2 The name given to the single-number rating is assigned by the test method that invokes this classification.1.3 Test methods that invoke this classification include:1.3.1 Test Method E90—The single-number rating is called sound transmission class (STC).1.3.2 Test Method E336—Single number ratings are noise isolation class (NIC), normalized noise isolation class (NNIC), and apparent sound transmission class (ASTC).1.3.3 Test Method E596—The single-number rating is called noise isolation class (NIC).1.3.4 Test Method E1414—The single-number rating is called ceiling attenuation class (CAC).1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.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.

4.1 Ratings are developed by some subjective or comparative evaluation criteria, or both, of a sample(s) to some reference criteria or when compared to a control sample. These parameters generally include change in gloss, color, surface texture, alterations to pattern and possibly restorability of appearance with normal maintenance procedures, including the use of finishes or buffing. Rating is done by a qualified individual or preferably by a panel of qualified observers under specified lighting conditions in accordance with prescribed procedures.1.1 This test method is intended to provide a numerical rating system for classification of resilient floors during the various stages of their wear life in relation to their condition, as perceived by a knowledgeable user.1.2 This test method is intended to allow comparison between two or more samples or groups of samples for differences in visual appearance.1.3 This method provides recommended viewing conditions and lighting for rating visual differences between samples or groups of samples.1.4 This method can be utilized to evaluate change in visual appearance before and after some specified test condition exposure, for example, in service wear due to foot traffic, or other tests where change in appearance might occur.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 problems, if any, associated with its use.

4.1 Defects in film are not acceptable to the end-user as there is a reduction in the fitness-for-use in many applications. This document is intended to be a practice to assist users in the inspection, quantification and observation of defects.4.2 This practice is applicable in a laboratory environment, continuous inspection as a quality control or as a research tool. It is also appropriate for use in any commercial process used to produce film including extrusion, calendaring, etc.4.3 This practice is also suitable for use as an evaluation or screening tool for materials intended to be used in other processes where defects of this nature are critical, such as fiber spinning non-woven, etc.4.4 Results achieved by different equipment, even from the same vendor in the same laboratory, are often not directly comparable as a bias exists that cannot be fully addressed through consistent operating conditions. Results frequently shift when analyzer components are upgraded. Additionally, results are often not directly comparable between different product types. All results are to be considered as relative values rather than absolute.4.4.1 Therefore, it is not recommended to provide absolute results as part of a sales contract between the buyer and seller. For sales contracts, it is recommended to establish product grade designations based on the historical relationship of the absolute results reported, and fitness-for-use or based on a reference material agreed by both parties. This is attained by the collection of data over a time-period to establish acceptable control limits.4.4.2 The defect size range of interest is usually different between resin supplier and converters. Total defect counts are not one to one comparable between small laboratory extrusion lines and commercial extrusion lines. Therefore, an individual correlation is the aim to get accepted results for fitness-for-use.NOTE 2: This was tested on Brabender, Collin, Goettfert, and OCS systems.4.5 For support in a basic interpretation of the different results the following points may be helpful for comparison.4.5.1 Size classes (number and definition)4.5.2 Reported defect types4.5.3 Comparable units (gels/kg, gels/m2, class system, index...)4.5.4 Vendor (type of equipment, for example, cast or blown film...)4.5.5 Camera settings (sensitivity, grey level, resolution...)4.5.6 Extrusion parametersNOTE 3: For attribute data such as defect counts, C-type control charts are most appropriate per recommendations within Practice E2587, Section 9.1.1 This practice intends to provide standardized approaches and criteria for the observation and reporting of defects in various types of plastic film, by means of an optical scanning system. includes the in situ inspection of defects in films fabricated for specific applications after preparation of a suitable film from plastic resin.1.2 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.NOTE 1: There is no known ISO equivalent to this standard.1.3 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.

ASTM D3359-23 Standard Test Methods for Rating Adhesion by Tape Test Active 发布日期 :  1970-01-01 实施日期 : 

5.1 In order for a coating is to fulfill its function of protecting or decorating a substrate, the coating must remain adhered to the substrate. Because the substrate and its surface preparation (or lack thereof) have a drastic effect on the adhesion of coatings, a method to evaluate adhesion of a coating to different substrates or surface treatments, or of different coatings to the same substrate, is of considerable usefulness in the industry.5.2 This test method is limited to evaluating lower levels of adhesion (see 1.3). The intra- and inter-laboratory precision of this test method is similar to other test methods for coated substrates (for example, Test Method D2370 and Test Method D4060), and is insensitive to all but large differences in adhesion. Limiting the range of rankings from 0 to 5 reflects the inability of this test method to make fine distinctions between levels of adhesion. Users shall not use intermediate values for ranking adhesion tests within this method.5.3 Extremes in temperatures or relative humidity may affect the adhesion of the tape or the coating.5.4 A given tape may not adhere equally well to different coatings due to several factors, including differences in coating composition and topology. As such, no single tape is likely to be suitable for testing all coatings. Furthermore, these test methods do not give an absolute value for the force required for bond rupture, but serves only as an indicator that some minimum value for bond strength was met or exceeded (1, 2).65.5 Operators performing these test methods must be trained and practiced in order to obtain consistent results. The accuracy and precision of the test result obtained by using these methods depends largely upon the skill of the operator and the operator's ability to perform the test in a consistent manner. Key steps that directly reflect the importance of operator skill include the angle and rate of tape removal and the visual assessment of the tested sample. It is not unexpected that different operators might obtain different results (1, 2).5.6 The standard requires that the free end of the tape be removed rapidly at as close to a 180° angle as possible. When the peel angle and rate vary, the force required to remove the tape can change dramatically due to the rheological properties of the backing and adhesive. Variation in pull rate and peel angle can effect large differences in test values and must be minimized to assure reproducibility (3).NOTE 1: These test methods have been reported being used to measure adhesion of organic coatings on non-metallic substrates (for example, wood and plastic), although related precision and bias data is lacking. If testing coatings on non-metallic substrates, either Test Method A or Test Method B may be more appropriate and the method employed should be discussed by interested parties. Issues with plastic substrates are noted in Appendix X1. A similar test method, ISO 2409, permits tests on non-metallic substrates (for example, wood and plaster). Precision and bias data on the latter is lacking. Test Method D3359 was developed with metal as the substrate and, in the absence of supporting precision and bias data, is so limited.1.1 These test methods cover procedures for assessing the adhesion of relatively ductile coating films to metallic substrates by applying and removing pressure-sensitive tape over cuts made in the film.1.2 Test Method A is primarily intended to rate the adhesion of coatings and coating systems greater than 125 μm (5 mils) in total thickness, while Test Method B is primarily intended to rate the adhesion of coatings and coating systems less than 125 μm (5 mils) in total thickness. Test Method B is not considered suitable for films thicker than 125 μm (5 mils) unless wider spaced cuts are employed and there is an explicit agreement between the purchaser and seller. If the thickness of the coating or coating system has not been predetermined, employ the use of a standard such as Practice D7091 or other appropriate standard agreed upon by interested parties prior to proceeding.1.3 These test methods are used to evaluate whether the adhesion of a coating to a substrate is adequate for the user’s application. They do not distinguish between higher levels of adhesion for which more sophisticated methods of measurement are required.1.4 This test method is similar in content (but not technically equivalent) to ISO 2409.1.5 In multicoat systems adhesion failure may occur between coats so that the adhesion of the coating system to the substrate is not determined.1.6 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.1.7 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.1.8 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.

ASTM D3052-23 Standard Practice for Rating Water-Emulsion Floor Polishes Active 发布日期 :  1970-01-01 实施日期 : 

3.1 When comparing different floor polishes for an actual field performance, it is important that all surfaces used be prepared in the same way. When this procedure is followed, variations in the test surfaces are minimized.1.1 This practice covers the comparison of the performance of water-emulsion floor polishes on test floors against a reference material. It is applicable to the following types of polishes:1.1.1 Wax emulsion polishes,1.1.2 Nonbuffable emulsion polishes,1.1.3 Detergent-resistant emulsion polishes, household type, and1.1.4 Detergent-resistant emulsion polishes, industrial type.1.2 Gloss, leveling, discoloration, traffic marking, slip resistance, and removal ease of these types of floor polishes is rated in comparison to a reference material. Where applicable, detergent resistance is also evaluated. This method is not to be considered as a recommended maintenance procedure.1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.1.4 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.1.5 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.

5.1 This test method is established to cover automated SEM/EDX-based procedures for:5.1.1 Rating the inclusion content of steels based on procedures listed in Standards E45 and E1245, with the significant difference that the composition of the individual inclusions, as determined by X-ray analysis, is utilized to sort them into chemical classes.5.1.2 Determining the number, size and morphological distribution of inclusions in steels sorted by chemical class.5.2 Methods 1 and 2 of this test method are primarily intended for rating the inclusion content of steels deoxidized with silicon or aluminum, both silicon and aluminum, or vacuum-treated steels without either silicon or aluminum additions. Guidelines are provided to rate inclusions in steel treated with rare earth additions or calcium-bearing compounds (13.4). When such steels are evaluated, the test report should describe the nature of the inclusions rated according to each inclusion category (A, B, C, D).5.3 Methods 1 and 2 will provide a quantitative rating of the inclusion content in half-severity number increments from 0 to 5 for each inclusion type and thickness (Method D of Test Method E45), and in tabulated in Table 2. Test Method E45 ratings by SEM may differ from those determined following E45 because of the use of chemistry in the classifications. In order to differentiate E45 ratings obtained using the SEM from traditional ratings using light microscopy, the ratings obtained using Method 1 or 2 of this Test Method shall be identified as E45-SEM1 and E45-SEM2, respectively.5.4 Method 3 defines procedures to analyze and report inclusions by arbitrary size distribution and chemical classifications. It may be made applicable to any material by appropriate choice of these classifications.5.4.1 Method 3 determines and reports basic (as used in Test Method E1245) stereological measurements (for example, volume fraction of sulfides and oxides, the number of sulfides or oxides per square millimeter, and so forth). This test method, however, does not address the measurement of such parameters. E45 ratings are not produced in Method 3 because the inclusion classifications do not follow those defined in Test Method E45.5.5 The quantitative results are intended to provide a description of the types and amounts of inclusions in a heat of steel. This test method contains no guidelines for such use.1.1 This test method covers procedures to obtain particle size distribution, chemical classification, and Test Methods E45 ratings of inclusions in steels using an automated scanning electron microscope (SEM) with X-ray analysis and automatic image analysis capabilities.1.2 There are three discrete methods described. Method 1 is the SEM analog of Test Method E45, which uses image analysis and light microscopy to produce automated Test Methods E45 ratings. Method 2 produces similar ratings based predominantly on sorting inclusions by chemistry into the traditional classes defined in Test Methods E45. Method 3 is recommended when explicit detail is needed on particular inclusion types, not necessarily defined in Test Methods E45, such as to verify the composition of inclusions in inclusion-engineered steel. Method 3 reports stereological parameters such as volume or number fraction, rather than Test Methods E45 type ratings.1.3 This test method deals only with the recommended test methods and nothing in it should be construed as defining or establishing limits of acceptability for any grade of steel or other alloy where the method is appropriate.1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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.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.
