ASTM D7268-12 - 1.2.2012
 
Significance and Use

Upon mutual agreement between the purchaser and the supplier, seamless knit garments 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 listed in Table 1. Therefore, one or more of the requirements in Table 1 may be modified by mutual agreement between the purchaser and the supplier.

In such cases, any references to the specifications should specify that: This product meets ASTM specifications XXXX except for the following characteristic(s).

Where no pre-purchase agreement has been reached between the purchaser and 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 a particular product.

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