适用范围：Test Methods A and B are used to establish the weight of the dart when 50 % of the specimens fail under the conditions specified.Data obtained by one test method cannot be compared directly with the other test method nor with those obtained from tests employing different conditions of missile velocity, impinging surface diameter, effective specimen diameter, and thickness. The values obtained by these test variables are highly dependent on the method of film fabrication.
