1.1 本规范涵盖了玄武岩纤维的要求，包括粗纱和短切原丝。本规范旨在通过为玄武岩纤维行业中通常制造的绞线产品指定通用术语来帮助最终用户。 1.2 玄武岩纤维是由自然火山岩（主要是玄武岩或其他玄武岩）熔融而产生的。熔体通过套管拉伸，通常在冷却时对光纤施胶。 1.3 玄武岩纤维束在特定条件下有多种一般用途，例如高物理或化学应力、高湿度或高温。特定条件下的性能要求由买方和供应商商定。 1.4 以国际单位或英寸-磅单位表示的数值应单独视为标准值。 每个系统中所述的值并不完全相等；因此，每个系统应独立于其他系统使用。将两个系统的值结合起来将导致不符合标准。 1.5 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）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》中确立的国际公认标准化原则制定的。

1.1 This specification covers the requirements for basalt fiber, including rovings and chopped strands. This specification is intended to assist ultimate users by designating the general nomenclature for the strand products that are generally manufactured in the basalt fiber industry. 1.2 Basalt fibers are produced by melting naturally occurring volcanic rocks, being primarily basalt or other basaltic rocks. The melt is drawn though a bushing and, typically, a sizing is applied to the fiber as it is cooled. 1.3 Basalt fiber strands have a variety of general uses under specific conditions, such as high physical or chemical stress, high moisture, or high temperature. Property requirements under specific conditions are agreed upon between the purchaser and the supplier. 1.4 The values stated in either SI units or inch-pound units are to be regarded separately 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 non-conformance with the standard. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 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.
