There’s a new ASTM C1036-11 that’s just been released. Titled “Standard Specification for Flat Glass,” the 9-page standard covers the requirements for annealed, monolithic flat soda-lime glass supplied as cut sizes or stock sheets. The new 2011 Edition replaces the previous ASTM C1036-06.
ASTM C1036 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 can be supplied as cut sizes or stock sheets. Two types of glasses can be used: Type I which is a transparent flat glass and Type II which is a patterned and wired flat glass. Type II glass has clear and tinted classes while Type I glass only has the clear class.
Different test methods for Type I glass can 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 can be determined after different tests: associated distortion and blemish appraisal, dimension, point blemish, reflectance, and transmittance.
