Standard Performance Specification for Vinyl-Coated and Urethane-Coated Upholstery Fabrics—Indoor

Fecha:
2019-01-28 /Active
Significance and Use:

4.1 Fabrics intended for this end-use should meet all the requirements listed in Table 1.

(A) There is more than one standard test method that can be used to measure breaking strength, tongue tear strength, and lightfastness. These test methods cannot be used interchangeably since there may be no overall correlation between them (see Note 2).
(B) grade in b and c is based on a numerical scale of 5 for negligible color transfer or color change to 1 for very severe color transfer or color change. The numerical rating in Table 1 or higher is acceptable.
(C) AATCC 9–Step Chromatic Transference Scale.
(D) AATCC Gray Scale for Color Change.

4.2 It should be recognized that fabric can be produced utilizing an almost infinite number of combinations of construction variables (e.g., type of fibers, percentage of fibers, yarn twist, yarn number, warp and pick count, chemical and mechanical finished). Additionally, fashion and aesthetics dictate that the ultimate consumer may find acceptable articles made from fabrics that do not conform to all of the requirements in Table 1.

4.2.1 Hence, no single performance specification can possibly apply to all the various fabrics that could be utilized for this end-use.

4.3 The uses and significance of particular properties and test methods are discussed in the appropriate sections of the specified methods.

Scope:

1.1 This performance specification covers performance requirements for vinyl-coated and urethane-coated upholstery fabrics produced with woven, knit, or nonwoven substrates which are used in the manufacture of new indoor furniture.

1.2 This performance specification is not applicable to fabrics used in porch, deck, or lawn furniture; nor for plain knit fabrics and plain, tufted, or flocked, woven upholstery fabrics.

1.3 These requirements apply to the length and width directions for those properties where fabric direction is pertinent.

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.
