1.1 本规范涵盖了拟用于喷涂玻璃纤维增强混凝土（GFRC）的耐碱（AR）玻璃纤维、玻璃纤维加强混凝土预混料、纤维加强混凝土和其他水泥基产品的最低要求。 1.2 本规范规定了易于掺入混凝土混合物中的AR玻璃纤维类型和配置、典型物理性能、最小氧化锆含量，并规定了确定符合这些要求的测试程序。 1.3 本规范未涉及纤维制造过程中使用的涂层或润滑剂的类型。 1.4 如果产品规范的更严格要求与本规范的要求之间存在冲突，应以产品规范为准。如果产品规范的要求或本规范的要求与采购订单中更严格的要求之间存在冲突，则以采购订单为准。 如果采购订单要求以任何方式违反了产品规范或本规范的要求，则采购订单要求不得优先；例如通过放弃测试要求或通过降低测试要求的严格性。 1.5 以国际单位制或英寸磅单位表示的数值应单独视为标准。在文本中，英寸磅单位显示在括号中。每个系统中规定的值可能不是完全相等的；因此，每个系统应独立使用。将两个系统的值合并可能导致不符合标准。 1.6 本标准并非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。 1.7 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 covers minimum requirements for alkali resistant (AR) glass fibers intended for use in glass fiber-reinforced concrete (GFRC) by spray-up, glass fiber-reinforced concrete premix, fiber-reinforced concrete, and other cementitious based products. 1.2 This specification provides for AR glass fiber types and configurations that can be readily incorporated into concrete mixes, typical physical properties, minimum zirconia content, and prescribes testing procedures to establish conformance to these requirements. 1.3 This specification does not address the types of coatings or lubricants used in the manufacturing process of the fibers. 1.4 In the case of conflict between a more stringent requirement of a product specification and a requirement of this specification, the product specification shall prevail. In the case of a conflict between a requirement of the product specification or a requirement of this specification and a more stringent requirement of the purchase order, the purchase order shall prevail. The purchase order requirements shall not take precedence if they, in any way, violate the requirements of the product specification or this specification; for example, by the waiving of a test requirement or by making a test requirement less stringent. 1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the inch-pound units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 1.6 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. 1.7 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.
