Significance and Use
Upon mutual agreement between the purchaser and the supplier, woven and knitted products intended for this end use should meet all of the requirements listed in Table 1 of this specification.
It is recognized that for purposes of fashion or aesthetics, the ultimate consumer of articles made from these fabrics may find acceptable products that do not conform to all of the requirements in Table 1. Therefore, one or more of the requirements listed in Table 1 may be modified by mutual agreement between the purchaser and the supplier.
In such cases, any references to the specification shall specify that: “This product meets ASTM Specification ____ except for the following characteristic(s).”
Where no prepurchase agreement has been reached between the purchaser and the supplier, and in case of controversy, the requirements listed in Table 1 are intended to be used as a guide only. As noted in 4.2, ultimate consumer demands dictate varying performance parameters for any particular product.
The uses and significance of particular properties and test methods are discussed in the appropriate sections of the specified test methods. For additional information see Test Methods D 629, Practice D 1776, and Guide D 3938.

1. Scope
1.1 This specification covers the evaluation of specific performance characteristics of importance in woven and knit flat, fitted, and waterbed sheet products for use in institutional and household environments.
1.2 This specification may be used by mutual agreement between the purchaser and the supplier to establish purchasing specification requirements.
1.3 The requirements in Table 1 apply to the length and width directions for those properties where fabric direction is pertinent.
1.4 This specification is not applicable to woven and knit products used for sheet blankets or to woven and knitted sheet products used for apparel.
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 and health practices and determine the applicability of regulatory limitations prior to use.

A There is more than one standard method that can be used to measure breaking force, bursting force, tear resistance, and lightfastness. These methods cannot be used interchangeably since there may be no overall correlation between them. See Notes 2-5 and Note 8.
B Recommended requirement for Easy Care Products which must be ironed.
C Class in colorfastness and 5A rating is based on a numerical scale of 5.0 for negligible color change, color transfer, or wrinkling to 1.0 for very severe color change, color transfer or wrinkling. The numerical rating in Table 1 or higher is acceptable.
D AATCC Gray Scale for Color Change.
E AATCC Gray Scale for Staining.
F AATCC Chromatic Transference Scale.
