5.1 These test methods may be used for acceptance testing of commercial shipments; however, caution is advised because information about between interlaboratory precision is incomplete. Comparative tests as directed in 5.1.1 may be advisable.5.1.1 If there are differences of practical significance between reported test results for two laboratories (or more), comparative tests should be performed to determine if there is statistical bias between them using competent statistical assistance. As a minimum, use test samples for such comparative tests that are as homogeneous as possible, drawn from the same lot of material as the samples that resulted in the disparate results during initial testing, and that are randomly assigned in equal numbers to each laboratory for testing. The test results from the laboratories should be compared using statistical test for unpaired data at a probability level chosen prior to the testing series. If a bias is found either its cause must be found and corrected, or future test results for that material must be adjusted in consideration of the known bias.5.2 These test methods are useful to evaluate quality and cost control during the manufacture of pile yarn floor covering.5.3 The significance and uses of particular properties and test methods are discussed in the appropriate sections of the specified test methods.1.1 This guide covers the procedures listed as follows for testing woven, knitted and nonwoven backing fabrics designed for use in the manufacture of pile yarn floor coverings. The procedures appear in the following order:  SectionBow and Skewness of Woven Fabrics  8Breaking Force of Woven and Nonwoven Fabrics 15Breaking Force After Tufting of Woven and Nonwoven Fabrics 16Extractable Matter  9Fabric Count of Woven Fabrics 12Fabric Count of Knitted Fabrics 13Length of Woven Fabrics 11Mass per Unit Area (Weight) of Woven Fabrics 14Width of Woven Fabrics 101.2 The values stated in inch-pound units are to be regarded as standard.

4.1 The determination of the mass per unit area of pile yarn floor covering is useful in quality and cost control during the manufacture of pile floor covering. Both appearance and performance may be affected by changes in mass per unit area.4.2 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 supplier should conduct comparison testing to determine if there is a statistical bias between their laboratories. Competent statistical assistance is recommended for the investigation of bias. As a minimum the two parties should take a group of test specimens that are as homogeneous as possible and that are from a lot of material of the type in question. The test specimens should then be randomly assigned 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 prior to testing. If a bias is found, either its cause must be found and corrected or the purchaser and supplier must agree to interpret future test results with consideration to the known bias.1.1 This test method covers the measurement of mass per unit area of machine-made woven, knitted, and tufted pile yarn floor covering both before and after an adhesive-back coating application.1.2 This test method encompasses three techniques for determination of mass per unit area as applicable:1.2.1 Section 7, for determining total mass per unit area, applies to both coated and uncoated (unfinished) pile floor coverings.1.2.2 Section 8, for determining component mass per unit area, applies only to uncoated (unfinished) pile yarn floor coverings.1.2.3 Section 9, for determining pile yarn mass per unit area, applies only to back-coated, or finished, pile yarn floor coverings.1.3 Determination of mass per unit area of pile yarn floor coverings was previously contained within Test Methods D418. For user convenience, Subcommittee D13.21 subdivided Test Methods D418 into separate standards, of which this test method is one.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 (except where shown in 1.4.1) and are not considered standard.1.4.1 The following sections are measured in SI units: Table 1, sections 9.8.4.2, 9.8.6.3 to 9.8.6.10, A2.1, A2.2, and A2.3.1.5 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. Specific precautionary statements are given in 9.5.1.6 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.

Steel materials shall undergo heat and product analysis. Steel specimens shall also undergo tensile tests and shall conform to the required values of yield point, yield strength, and tensile strength.1.1 This specification covers carbon, low-alloy, high-strength low-alloy, and alloy steel hot-rolled floor plates for flooring, stairways, transportation equipment, and general structural purposes. While it is generally provided in the as-rolled condition, floor plate also may be provided in the heat-treated condition, depending on the material specification. Rolled floor plates have raised figures at regular intervals on one surface of the plate.1.2 Floor plate is available in dimensions that meet the classification size limits for sheet, heavy thickness sheet coil, or plate. Maximum thickness for product delivered under this specification is 1 in. [25 mm].1.3 When the steel is to be welded, it is presupposed that a welding procedure suitable for the grade of steel and intended use or service will be utilized. See Appendix X3 of Specification A6/A6M for information on weldability.1.4 The values stated in either inch-pound units or SI units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and the values from the two systems shall not be combined.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 This test method may be used to evaluate the difference in gloss of dried films of emulsion floor polishes when the light reflected at a 60° angle is measured. Extremely high- or low-gloss polishes may not be differentiated at a 60° angle. A20° angle measured in accordance with Test Method D523 may give better definition of gloss.1.1 This test method covers the determination of the 60° specular gloss of films of emulsion floor polish after application to a substrate.NOTE 1: Specular gloss is one of several related appearance attributes that produce the sensation of glossiness. For this reason, specular gloss measurements may not always correlate well with visual rankings of glossiness.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.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.
