标准范围

ISO 179-1:20 10规定了在规定条件下测定塑料夏比冲击强度的方法。定义了许多不同类型的样本和测试配置。根据材料类型、试件类型和缺口类型规定不同的试验参数。该方法可用于研究特定类型试样在规定的冲击条件下的行为,并用于在试验条件固有的限制范围内估计试样的脆性或韧性。它也可用于确定类似类型材料的比较数据。该方法比ISO 180(Izod冲击试验)中给出的方法具有更大的适用范围,并且更适合于测试显示层间剪切断裂的材料或由于环境因素而显示表面效应的材料。该方法适用于以下范围的材料:刚性热塑性模制和挤出材料(除了未填充类型之外,还包括填充和增强化合物)和刚性热塑性片材;刚性热固性模制材料(包括填充和增强化合物)和刚性热固性片材(包括层压板);纤维增强的热固性和热塑性复合材料,其包含单向或多向增强材料(例如垫、机织物、机织物粗纱、短切股线、组合和混合增强材料、粗纱和碾磨纤维)或包含由预浸渍材料(预浸料)制成的片材,包括填充化合物;热致液晶聚合物。

ISO 179-1:2010 specifies a method for determining the Charpy impact strength of plastics under defined conditions. A number of different types of specimen and test configurations are defined. Different test parameters are specified according to the type of material, the type of test specimen and the type of notch.The method can be used to investigate the behaviour of specified types of specimen under the impact conditions defined and for estimating the brittleness or toughness of specimens within the limitations inherent in the test conditions. It can also be used for the determination of comparative data from similar types of material.The method has a greater range of applicability than that given in ISO 180 (Izod impact testing) and is more suitable for the testing of materials showing interlaminar shear fracture or of materials exhibiting surface effects due to environmental factors.The method is suitable for use with the following range of materials:

  • rigid thermoplastic moulding and extrusion materials (including filled and reinforced compounds in addition to unfilled types) and rigid thermoplastics sheets;
  • rigid thermosetting moulding materials (including filled and reinforced compounds) and rigid thermosetting sheets (including laminates);
  • fibre-reinforced thermosetting and thermoplastic composites incorporating unidirectional or multi-directional reinforcements (such as mats, woven fabrics, woven rovings, chopped strands, combination and hybrid reinforcements, rovings and milled fibres) or incorporating sheets made from pre-impregnated materials (prepregs), including filled compounds;
  • thermotropic liquid-crystal polymers.
