Upon mutual agreement between the purchaser and seller, fabrics intended for this end use should meet all 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 fabrics 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 seller.

If any of the requirements in Table 1 are modified by mutual agreement between purchaser and seller, any reference to the specification shall state that: "This fabric meets ASTM Specification D4769, except for the following characteristic(s)."

Where no prepurchase agreement has been reached between the purchaser and seller, and in case of controversy, the requirements listed in Table 1 are intended to be used as a guide only. As stated in 5.2, ultimate consumer demands dictate varying performance parameters for any particular style of fabric.

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