5.1 This specification serves as a guide for the purchase of zippers to be used for dungarees, jeans or work trousers.

5.2 Upon agreement between the purchaser and the supplier, zippers intended for this end-use should meet all of the requirements listed in Table 1 of this specification.

5.3 It is recognized that for purposes of fashion or aesthetics the ultimate consumer may find acceptable dungarees, jeans or work trousers, having zippers 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 agreement between the purchaser and the supplier.

5.4 Where no prepurchase agreement has been reached between the purchaser and the supplier, and in case of controversy, the requirements listed in Table 1 are intended to be used as a guide only. As noted in 5.3 ultimate consumer demands dictate varying performance parameters for any particular style of zipper.

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