Standard Specification for Flat Glass

Abstract

This specification covers the quality requirements of flat, transparent, clear, and tinted glass. This glass is intended to be used primarily for architectural glazing products including: coated glass, insulating glass units, laminated glass, mirrors, spandrel glass, or similar uses. The monolithic flat glass shall be supplied as cut sizes or stock sheets. Two types of glasses shall be used: Type I which is a transparent flat glass and Type II which is a patterned and wired flat glass. Type II glass shall have clear and tinted classes while Type I glass shall only have the clear class. Different test methods for Type I glass shall be performed in order to determine the following properties: point blemish and linear blemish content, ream distortion, string distortion, line distortion, dimension, squareness, reflectance, and transmittance. As for the type II glass the following properties shall be determined after different tests: associated distortion and blemish appraisal, dimension, point blemish, reflectance, and transmittance.
