Knitted fabrics should meet all of the requirements in Table 1 to be suitable for use in the manufacture of dress suits and sportswear jackets, slacks, and trousers for men and boys.

It is recognized that for purposes of fashion or aesthetics the ultimate consumer of articles made from these fabrics may find acceptable some fabrics that do not conform to all of the requirements in Table 1. For example, the fabric could be dyed in shades that do not meet the requirement in Table 1 for colorfastness to light, yet be acceptable to the ultimate consumer because the shade is fashionable. In such cases, one or more of the requirements may be modified by mutual agreement between the purchaser and the seller.

If any of the requirements in Table 1 are modified by mutual agreement between the purchaser and the seller, any reference to the specification shall specify that “this fabric meets ASTM Specification D 3782 except for the following characteristic(s).”

The uses and significance of particular properties are discussed in the appropriate sections of the specific methods.

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 and health practices and determine the applicability of regulatory limitations prior to use.
