标准范围

ISO 1874-1:20 10建立了聚酰胺（PA）热塑性材料的名称系统，该系统可用作规范的基础。它涵盖了基于PA 6、PA 66、PA 69、PA 610、PA 612、PA 11、PA 12、PA MXD6、PA 46、PA 1212、PA 4T、PA 6T和PA 9T的用于模塑和挤出的聚酰胺均聚物以及用于模塑和挤出的各种组合物的共聚酰胺。聚酰胺塑料的类型通过基于指示性质的适当水平的分类系统彼此区分粘度数、拉伸弹性模量和成核剂的存在，以及有关化学结构、预期用途、加工方法、重要性能、添加剂、颜色、填料和增强材料的信息。该命名系统适用于所有聚酰胺均聚物和共聚物。它适用于准备正常使用的、未经改性的和经着色剂、添加剂、填料、增强材料、聚合物改性剂等改性的材料。它不适用于PA6和PA12的单体浇铸型聚酰胺。

ISO 1874-1:2010 establishes a system of designation for polyamide (PA) thermoplastic materials, which may be used as the basis for specifications.It covers polyamide homopolymers for moulding and extrusion based on PA 6, PA 66, PA 69, PA 610, PA 612, PA 11, PA 12, PA MXD6, PA 46, PA 1212, PA 4T, PA 6T and PA 9T and copolyamides of various compositions for moulding and extrusion.The types of polyamide plastic are differentiated from each other by a classification system based on appropriate levels of the designatory properties

1. viscosity number,
2. tensile modulus of elasticity and
3. presence of nucleating agent,

and on information about chemical structure, intended application, method of processing, important properties, additives, colour, fillers and reinforcing materials.The designation system is applicable to all polyamide homopolymers and copolymers. It applies to materials ready for normal use, unmodified and modified by colorants, additives, fillers, reinforcing materials, polymer modifiers, etc.It does not apply to monomer casting-type polyamides of PA 6 and PA 12.
