Test methods for measuring those properties have not been published either because no practical methods have yet d206 developed or because a valid evaluation of the adtm resulting from existing unpublished methods requires an intimate and thorough knowledge of zippers. Position the slider at the point FIG. B No standard number of specimens is given for these tests since they are quite variable and are not recommended for acceptance testing except where the laboratories of the purchaser and the seller have established their precision and bias, if any.
