耐机械冲击性能是材料的重要物理力学性能,直接影响到产品的使用价值,在许多标准中都被列为主要考核项目。为简化操作和模拟实际使用的情况,很多时候是通过落锤冲击的方式来实现的。如塑料给排水管材管件采用的G B/T14153-1993《硬质塑料落锤冲击试验方法通则》,又如PVC电线槽 Resistance to mechanical impact properties of the material is an important physical and mechanical properties, a direct impact on product value, in many standards are listed as the main assessment items. To simplify the operation and simulate the actual use of the situation, often through the drop hammer impact to achieve. Such as plastic pipe fittings to water and drainage G B / T14153-1993 “hard plastic drop hammer impact test methods General,” Another example PVC wire slot
