1.1 本试验方法包括测定在热控制连续或振荡输送炉中处理的热强化和全钢化建筑玻璃基板的光学变形。见规范 C1036 和 C1048 用于讨论如此处理的玻璃的特性。在本试验方法中，对加工玻璃的反射图像进行拍照，并对拍照图像进行分析，以量化由于表面波纹度引起的变形。该测试方法还可用于量化夹层玻璃组件中透射光中观察到的光学畸变。 1.2 以国际单位或英寸-磅单位表示的数值单独视为标准值。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。 1.3 没有已知的ISO等效于该试验方法。 1.4 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。 1.5 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。 ====意义和用途====== 5.1 本试验方法为评估被检玻璃的光学性能提供了准确数据。 5.2 所述程序有助于观察平板建筑玻璃钢化过程中引入的滚波。 ( 1. ) 5.3 本试验方法也适用于在透射光下检查平板和曲线几何形状的夹层和钢化汽车玻璃。

1.1 This test method covers the determination of optical distortion of heat-strengthened and fully tempered architectural glass substrates which have been processed in a heat controlled continuous or oscillating conveyance oven. See Specifications C1036 and C1048 for discussion of the characteristics of glass so processed. In this test method the reflected image of processed glass is photographed and the photographic image analyzed to quantify the distortion due to surface waviness. The test method is also useful to quantify optical distortion observed in transmitted light in laminated glass assemblies. 1.2 The values stated in either SI units or inch-pound units are 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 nonconformance with the standard. 1.3 There is no known ISO equivalent to this test method. 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. ====== Significance And Use ====== 5.1 This test method provides accurate data for evaluation of the optical properties of the glass being inspected. 5.2 The procedure described is useful for observing the roll wave introduced during the tempering process of flat architectural glass. ( 1 ) 5.3 This test method is also useful for inspection of laminated and tempered automotive glass in transmitted light, in both flat and curved geometries.
