1.1 ISO 14527的这一部分建立了脲醛和 尿素/三聚氰胺-甲醛粉末模塑料（UF-和UF/MF-PMC）。 1.2各种类型的UF-和UF/MF-PMC通过分类系统彼此区分 基于关于填料/增强材料类型和含量、预期加工方法、任何 特殊属性和专门用于指定目的的特殊属性（指定 属性）。 1.3 ISO 14527的这一部分适用于以粉末形式准备正常使用的所有UF和UF/MF-PMC， 颗粒或研磨材料。 1.4这并不意味着具有相同名称的材料必然给出相同的名称 性能。ISO 14527的这一部分不提供工程数据、性能数据或加工数据 为特定应用和/或加工方法指定材料可能需要的条件。如果 如果需要此类附加性能，则应按照中规定的试验方法进行测定 ISO 14527-2，如果适用。 1.5只要需要标明ISO 14527-3所涵盖的一般要求数据，也应这样做 使用这个数据块系统。 1.6确保代码字母和代码保持明确，并避免在 在数据块1、2或3中使用的任何新代码字母或代码编号应在使用前获得 ISO/TC 61/SC 1、SC 12和SC 13的秘书处。

1.1 This part of ISO 14527 establishes a data block system for the designation of urea-formaldehyde and urea/melamine-formaldehyde powder moulding compounds (UF- and UF/MF-PMCs). 1.2 The various types of UF- and UF/MF-PMC are differentiated from each other by a classification system based on information about the filler/reinforcement type and content, the intended method of processing, any special properties and those of the special properties used specifically for designation purposes (designatory properties). 1.3 This part of ISO 14527 is applicable to all UF- and UF/MF-PMCs ready for normal use in the form of powder, granules or ground material. 1.4 It is not intended to imply that materials having the same designation necessarily give the same performance. This part of ISO 14527 does not provide engineering data, performance data or data on processing conditions which may be required to specify a material for a particular application and/or method of processing. If such additional properties are required, they shall be determined in accordance with the test methods specified in ISO 14527-2, if suitable. 1.5 Whenever general requirement data, as covered by ISO 14527-3, need to be indicated, this is also done using this data block system. 1.6 To ensure that code-letters and code-numbers remain unambiguous, and to avoid conflicts within the system, any new code-letters or code-numbers for use in data block 1, 2 or 3 shall be approved before use by the secretariats of ISO/TC 61/SC 1, SC 12 and SC 13.
