BS EN ISO 15023-1:2017建立了聚乙烯醇（PVAL）材料的命名体系，可作为规范的基础。聚乙烯醇（PVAL）材料的类型通过基于指定性质的分类系统相互区分:a）水解度，b）水溶液在规定条件下的粘度，以及关于基本聚合物参数、预期用途和/或加工方法、重要性质、添加剂、着色剂、，填料和增强材料。本文件适用于水解度不低于70 mol%的所有聚乙烯醇（PVAL）材料。 它适用于以粉末、颗粒或颗粒形式准备正常使用的材料，以及未经着色剂、添加剂、填料等改性或改性的材料。它并不意味着具有相同名称的材料必须具有相同的性能。本文件不提供指定材料所需的工程数据、性能数据或加工条件数据。如果需要此类附加性能，则应按照ISO 15023中规定的试验方法进行测定？2.如果合适的话。为了指定热塑性材料满足特定规范，数据块5中给出了要求（见4）。 1).交叉引用:ISO 15023-2:2003（R07）Ed 1ISO 1043-1:2011ISO 472:2013 ED4 ISO 1043-2:2011 Ed 3购买时可用的所有当前修订版均包含在本文件的购买中。

BS EN ISO 15023-1:2017 establishes a system of designation for poly(vinyl alcohol) (PVAL) materials which may be used as the basis for specifications.The types of poly(vinyl alcohol) (PVAL) materials are differentiated from each other by a classification system based on the designatory properties:a)degree of hydrolysis,b)viscosity of aqueous solution under defined conditionsand on information about basic polymer parameters, intended application and/or method of processing, important properties, additives, colorants, fillers and reinforcing materials.This document is applicable to all poly(vinyl alcohol) (PVAL) materials with a degree of hydrolysis not less than 70 mol%.It applies to materials ready for normal use in the form of powder, granules or pellets and to materials unmodified or modified by colorants, additives, fillers, etc.It is not intended to imply that materials having the same designation give necessarily the same performance.This document does not provide engineering data, performance data or data on processing conditions which may be required to specify a material. If such additional properties are required, they are intended to be determined in accordance with the test methods specified in ISO 15023?2, if suitable.In order to designate a thermoplastic material to meet particular specifications, the requirements are given in data block 5 (see 4.1).Cross References:ISO 15023-2:2003 (R07) Ed 1ISO 1043-1:2011ISO 472:2013 ED4 ISO 1043-2:2011 Ed 3All current amendments available at time of purchase are included with the purchase of this document.
