1.1 本试验方法包括通过使用深度小于等于1.0 in.（25.4 mm）的简支梁，使用第三点荷载，测定玻璃纤维混凝土截面的弯曲极限强度和屈服强度。 1.2 以英寸磅为单位的数值应视为标准。括号中给出的值仅供参考。 1.3 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。 1.4 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。 ====意义和用途====== 3.1 通过该测试方法确定的弯曲性能有助于玻璃纤维混凝土产品的质量控制，确定是否符合管理规范，研究和开发，并生成用于产品设计的数据。

1.1 This test method covers determination of the flexural ultimate strength in bending and the yield strength of glass-fiber reinforced concrete sections by the use of a simple beam of 1.0 in. (25.4 mm) or less in depth using third-point loading. 1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only. 1.3 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. 1.4 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. ====== Significance And Use ====== 3.1 Flexural properties determined by this test method are useful for quality control of glass-fiber reinforced concrete products, ascertaining compliance with the governing specifications, research and development, and generating data for use in product design.
