ActivePlastics film and sheeting - Determination of impact resistance by the free-falling dart methord - Part 1: Staircase methords
塑料薄膜和薄片 抗冲击性能试验方法 自由落镖法 第1部分：梯级法
Application Summary AI generated
This standard specifies a staircase method for determining the impact resistance of plastic film and sheeting by measuring the energy required to cause failure from a free-falling dart. It is applied in quality control and material testing within the plastics packaging industry, particularly for evaluating the toughness of thin films used in bags, wraps, and laminates. The test is conducted under controlled laboratory conditions to assess product durability during handling and transportation.
