标准范围

所述冲击渗透试验用于评估塑料薄膜和薄板在与薄膜平面成直角的冲击应力下的性能。如果在冲击器几乎恒定的速度下记录的力变形或力-时间图对于表征冲击特性是必要的，则使用第2部分。该试验方法适用于厚度不超过1 mm的薄膜，可以比较薄膜的冲击穿透力、双轴变形能力和能量吸收能力。

The impact-penetration test described is used for the assessment of plastic films and thin sheets under an impact stress applied at right angles to the plane of the film. This part 2 is used if a force-deformation or a force-time diagram, recorded at practically constant velocity of the striker, is necessary for characterization of the impact behaviour. The test method is applicable to films of up to 1 mm thickness and makes it possible to compare impact-penetration forces, biaxial deformabilities and energy-absorption capacities of films.
