1.1 本试验方法描述了测试有釉或无釉陶瓷或玻璃砖耐反复冻融循环所需的程序和设备。任何尺寸或形状的瓷砖都可以通过这种测试方法进行测试。 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====== 4.1 耐冻融性试验可作为选择适用于冰冻地理区域户外服务的陶瓷和玻璃砖的指南。它可以作为一种测试方法来验证是否符合陶瓷和玻璃砖的规范，并提供一种控制测试来确定为外部安装制造的瓷砖的抗冻融性。

1.1 This test method describes the procedures and equipment required to test either glazed or unglazed ceramic or glass tiles for resistance to repeated cycles of freezing and thawing. Tiles of any size or shape may be tested by this test method. 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 ====== 4.1 The test for resistance to freezing and thawing functions as a guide to the selection of ceramic and glass tiles suitable for outdoor service in geographic areas subjected to freezing. It can serve as a test method to verify compliance with specifications for ceramic and glass tiles, and provides a control test for determining the freeze/thaw resistance of tiles being manufactured for exterior installations.
