Significance and Use

Upon mutual agreement between the purchaser and the supplier, woven or knitted products intended for this end use should meet all of the requirements listed in Table 1 of this specification for terry products and Table 2 for non terry products.

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 or Table 2. Therefore, one or more of the requirements listed in Table 1 or Table 2 may be modified by mutual agreement between the purchaser and the seller.

In such cases, any references to the specification shall specify that: This product meets ASTM Specification 63-707 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 or Table 2 are intended to be used as a guide only. As noted in 5.2, ultimate consumer demands dictate varying performance parameters for any particular style.

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

Scope

1.1 This specification covers the evaluation of specific performance characteristics of importance in woven and knitted kitchen towel, dishcloth, crash towel, huck towel, washcloth, hand towel, bath towel, and bath 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 Tables 1 and 2 apply to the length and width directions for those properties where fabric direction is pertinent.

1.4 This specification is not applicable for coated and laminated products, nonwoven products, or terry fabrics used for apparel.

1.5 This standard does not purport to address all of the safety problems, 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.
