1.1 本试验方法适用于主要用于支撑螺旋石膏板产品的金属吊顶格栅系统。 1.2 吊顶格栅系统构件强度特性的确定方法如下: 测验 小节 均匀载荷试验 6 – 10 连接强度测试 11 – 15 导线拉出电阻 16 – 20 1.3 以英寸-磅和国际单位制（公制）表示的数值应单独视为标准。在文本中，SI（公制）单位显示在括号中。每个单位制中规定的值应独立于其他单位使用。 不得将两种单位制的值合并。 1.4 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。 1.5 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 test method covers metal suspended ceiling grid systems used primarily to support screw-attached gypsum panel products. 1.2 The method of determining strength properties of suspended ceiling grid system components is as follows: Tests Sections Uniform Load Testing 6 – 10 Connection Strength Testing 11 – 15 Wire Pullout Resistance 16 – 20 1.3 The values stated in inch-pound and SI (metric) units are to be regarded separately as standard. Within the text, the SI (metric) units are shown in brackets. The values stated in each system of units shall be used independently of the other. Values from the two systems of units shall not be combined. 1.4 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. 1.5 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.
