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.
