1.1 本规范主要涵盖由“E”电连续玻璃纤维粗纱编织而成的玻璃织物，该玻璃织物主要用作结构用层压塑料的增强材料。 1.2 本规范规定了玻璃纤维粗纱织物的术语、定义、一般要求和物理要求。本规范允许在玻璃纤维粗纱的制造过程中使用上浆材料，这有助于织造。在本规范允许的情况下使用时，此类材料与合同文书中规定的树脂基体相容。 注1: 在大多数情况下，玻璃纤维纱线上的上浆材料通过各种清洁程序去除，作为制备成品织物的第一阶段。 当这些纱线上浆材料在清洁过程中被去除时，它们不需要与随后的树脂基体相容。 1.3 单位-- 以国际单位制或英寸磅单位表示的数值应视为标准。每个系统中规定的数值并不完全相等；因此，每个系统应独立使用。将两个系统的值结合起来会导致不符合标准。 注2: 本规范是以下军事规范的替代品系列之一: MIL-Y-1140H纱线、帘线、套管、布和胶带玻璃 MIL-C-9084C树脂层压板用玻璃布 MIL-C-19663C塑料层压板用玻璃机织粗纱布 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。

1.1 This specification primarily covers glass fabrics woven from “E” electrical continuous glass fiber rovings that are intended primarily as a reinforcing material in laminated plastics for structural use. 1.2 This specification specifies the terminology, definitions, general requirements, and physical requirements for woven roving glass fiber fabrics. This specification permits the application of sizing materials to the glass fiber roving during manufacture that helps facilitate weaving. When used as permitted in this specification, such materials are compatible with the resin matrix as specified in the contracting instrument. Note 1: Sizing materials on glass fiber yarns, in most cases, are removed by various cleaning procedures as a first stage in preparing a finished fabric. When these yarn sizing materials are removed during a cleaning procedure, they need not be compatible with the subsequent resin matrix. 1.3 Units— The values stated in either SI units or inch-pound units are to be regarded as standard. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems will result in nonconformance with the standard. Note 2: This specification is one of a series to provide a substitute for the following Military Specifications: MIL-Y-1140H Yarn, Cord, Sleeving, Cloth, and Tape-Glass MIL-C-9084C Cloth, Glass Finished for Resin Laminates MIL-C-19663C Cloth, Glass, Woven Roving for Plastic Laminates 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
