1.1 本规范涵盖了用于纤维增强混凝土和其他水泥制品的纤维素纤维的最低要求。 1.2 本规范规定了性能测量、类型定义、典型性能，并规定了测试程序，以确定是否符合这些要求。 1.3 如果产品规范的更严格要求与本规范的要求相冲突，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产品规范或本规范的要求，则不得优先考虑采购订单要求；例如，通过放弃测试要求或降低测试要求的严格程度。 1.4 以国际单位制或英寸-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是精确的等效值；因此，每个系统应相互独立使用。将两个系统的值合并可能会导致不符合标准。 1.5 本标准并非旨在解决与其使用相关的所有安全问题（如有）。 本标准的用户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 minimum requirements for cellulose fibers intended for use in fiber-reinforced concrete, and other cementitious products. 1.2 This specification provides for measurement of properties, definition of types, typical properties, and prescribes testing procedures to establish conformance to these requirements. 1.3 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. 1.4 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 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.
