摘要
本文介绍了ASTMC1048-04热处理平板玻璃的标准规范，其中包括HS类、FT类镀膜和非镀膜玻璃等特性和要求。首先介绍了玻璃的冰丝压痕试验、抗折强度试验和光学折射率试验的规定，然后介绍了玻璃的热处理要求问题，包括玻璃冷处理、热处理、复合处理、滚轧处理的详细要求，最后介绍了宏观和微观外观、形状和尺寸、玻璃厚度精度、肖特基系数和表面电阻率等特性的规范要求。
1. Introduction
This standard specifies the properties and requirements for HS class, FT class coated and uncoated plate glass produced by thermal treatment.
2. Requirements
2.1 Tests: Ice-Bearing Test, Bending Strength Test and Refractive Index Test.
2.3 Specification Requirements: macro and micro appearance, shape and size, glass thickness accuracy, netic coefficients and surface resistance.
3. Ice-Bearing Test
3.1 General: Ice-bearing test shall be carried out on a piece of plate glass with a thickness of 10mm or more.
3.2 Apparatus: An apparatus for testing the ice-bearing capacity of plate glass.
3.3 Procedure: The test piece is placed on a special device and then put in a place with a temperature of -20°C to -25°C. After 15 minutes, the test piece should be removed from the apparatus and observed.
4. Bending Strength Test
4.1 General: Bending strength test shall be carried out on a piece of plate glass with a thickness of 10mm or more.
4.2 Apparatus: An apparatus for testing the bending strength of plate glass.
4.3 Procedure: The test piece is placed on a special device and then subjected to a bending load. The bending load is then released, and the test piece is observed to determine the bending strength.
5. Refractive Index Test
5.1 General: Refractive index test shall be carried out on a piece of plate glass with a thickness of 10mm or more.
5.2 Apparatus: An apparatus for testing the refractive index of plate glass.
5.3 Procedure: The test piece is placed on a special device and then subjected to a light beam. The light beam is then released, and the test piece is observed to determine the refractive index.
