标准范围

规定了测定能量的方法，该能量会导致厚度小于1 mm的塑料薄膜和薄板在规定高度的自由落体飞镖冲击的规定条件下失效，该能量会导致50%的试验样品失效。描述了两种方法。方法A使用直径为38 mm的半球形头部的省道，从0.66 m的高度落下，方法B使用直径为50 mm的半球形头部的省道，从1.50 m的高度落下。测量技术为stairecase方法。

Specifies methods for the determination of the energy, that causes plastics films and sheet less than 1 mm in thickness to fail under specified conditions of impact of a free falling dart from a specified height, tha would result in failure of 50 % of the specimes tested. Two methods are described. Method A employs a dart with 38 mm diameter hemispherical head, dropped from a height of 0,66 m, and method B employs a dart with a 50 mm diameter hemispherical head dropped from a height of 1,50 m. The measurement technique is the stairecase method.
