Scope

1.1 These test methods cover the construction testing of machine-made woven, knitted, and tufted pile yarn floor covering both before and after an adhesive back coating, which bonds the pile yarn to the backing fabric, has been applied. 1.2 This standard includes the following test methods: Section Component Masses2 per Unit Area 8 Number of Binding Sites per Unit Length or Width of Floor Covering 16 Number of Binding Sites per Unit Length or Width of Pile Floor Covering 21 Pile Thickness—Level Pile 10 Pile Thickness—Multilevel Pile 11 Pile Yarn Length per Unit Length of Floor Covering 14 Pile Yarn Length per Unit Length of Floor Covering 20 Pile Yarn Mass per Unit Area 9 Total Mass per Unit Area 7 Tuft and Yarn Length of Uncoated Floor Covering 18 Tuft Length 12 Tuft Length 19 Tuft Length for Level Loop Pile Floor Covering 15 Tuft Height 13 1.2.1 Specimen preparation procedures common to Sections 7-11 are presented in Annex A1, Preparing Specimens of Measured Area. Annex A2 and Annex A3 give examples of typical calculations for Sections 9-11. 1.3 The values stated in inch-pound units are to be regarded as the standard for all measurements except mass. The SI (metric) values for all measurements except mass are provided for information purposes only. 1.4 This standard may involve the use of hazardous materials, operations and equipment. It is the responsibility of the user of this standard to establish appropriate safety practices and to determine the applicability of regulatory limitations prior to use.
