1.1本文件规定了在规定条件下测定塑料和塑料复合材料拉伸性能的一般原则。定义了几种不同类型的试样，以适应不同类型的材料，这在ISO 527的后续部分中有详细说明。 1.2这些方法用于研究试样的拉伸行为，并用于确定在规定条件下拉伸强度、拉伸模量和拉伸应力/应变关系的其他方面。 1.3这些方法选择性地适用于以下材料: -刚性和半刚性模制、挤出和铸造热塑性材料，除了未填充类型之外，还包括填充和增强化合物；刚性和半刚性热塑性塑料片材和薄膜；-刚性和半刚性热固性模制材料，包括填充和增强化合物；刚性和半刚性热固性片材，包括层压板； -包含单向或非单向增强物的纤维增强热固性和热塑性复合材料，例如垫、机织物、机织粗纱、短切股线、组合和混合增强物、粗纱和碾磨纤维；由预浸渍材料(预浸料)制成的片材； -热致液晶聚合物。 这些方法通常不适用于使用ISO 1926的刚性多孔材料或含有多孔材料的夹层结构。

1.1 This document specifies the general principles for determining the tensile properties of plastics and plastic composites under defined conditions. Several different types of test specimen are defined to suit different types of material which are detailed in subsequent parts of ISO 527. 1.2 The methods are used to investigate the tensile behaviour of the test specimens and for determining the tensile strength, tensile modulus and other aspects of the tensile stress/strain relationship under the conditions defined. 1.3 The methods are selectively suitable for use with the following materials: — rigid and semi-rigid moulding, extrusion and cast thermoplastic materials, including filled and reinforced compounds in addition to unfilled types; rigid and semi-rigid thermoplastics sheets and films; — rigid and semi-rigid thermosetting moulding materials, including filled and reinforced compounds; rigid and semi-rigid thermosetting sheets, including laminates; — fibre-reinforced thermosets and thermoplastic composites incorporating unidirectional or non-unidirectional reinforcements, such as mat, woven fabrics, woven rovings, chopped strands, combination and hybrid reinforcement, rovings and milled fibres; sheet made from pre-impregnated materials (prepregs); — thermotropic liquid crystal polymers. The methods are not normally suitable for use with rigid cellular materials, for which ISO 1926 is used, or for sandwich structures containing cellular materials.
