ASTM C1279-23
退火、热强化和完全回火平板玻璃边缘和表面应力的无损光弹性测量的标准试验方法

适用范围: 1.1 This test method covers the determination of edge stresses and surface stresses in annealed, heat-strengthened, and fully tempered flat glass products. 1.2 This test method is non-destructive. 1.3 This test method uses transmitted light and is, therefore, applicable to light-transmitting glasses. 1.4 The test method is not applicable to chemicallytempered glass. 1.5 Using the procedure described, surface stresses can be measured only on the “tin” side of float glass. 1.6 Surface-stress measuring instruments are designed for a specific range of surface index of refraction. 1.7 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.8 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. 1.9 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.
