1.1 本规范涵盖了用于纤维增强混凝土的钢纤维的最低要求。为此，五种类型的钢纤维被定义为光滑或变形的冷拉钢丝；光滑或变形的切割板材；熔融提取纤维；工厂切割或改良的冷拉钢丝钢纤维，足够小，可以随意分散在混凝土混合物中。 1.2 本规范规定了尺寸测量、规定尺寸的公差和要求的最低物理性能，并规定了测试程序，以确定是否符合这些要求。 1.3 如果产品规范要求与本规范要求之间存在冲突，应以产品规范为准。如果产品规范或本规范的要求与采购订单的更严格要求之间存在冲突，应以采购订单为准。 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，则不应优先考虑这些要求；例如，通过放弃测试要求或降低测试要求的严格程度。 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。每个系统中规定的值可能不完全相等；因此，每个系统应独立于其他系统使用。结合两个系统的值可能会导致不符合标准。 1.5 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 minimum requirements for steel fibers intended for use in fiber-reinforced concrete. Five types of steel fibers for this purpose are defined as pieces of smooth or deformed cold-drawn wire; smooth or deformed cut sheet; melt-extracted fibers; mill-cut or modified cold-drawn wire steel fibers that are sufficiently small to be dispersed at random in a concrete mixture. 1.2 This specification provides for measurement of dimensions, tolerances from specified dimensions, and required minimum physical properties, and prescribes testing procedures to establish conformance to these requirements. 1.3 In the case of conflict between a 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. 1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system 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. 1.5 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.
