(Specification)Standard Specification for Flat Glass
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.
SCOPE
1.1 This specification covers the requirements for annealed, monolithic flat soda-lime glass supplied as cut sizes or stock sheets.
1.2 This specification is applicable for laboratory and field evaluation only to the extent that such evaluation can be carried out in accordance with the test method(s) prescribed herein.
1.3 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.
Note 1—Reflective distortion is not addressed in this specification.
1.4 This specification covers the quality requirements of patterned or wired glasses intended to be used primarily for decorative and general glazing applications.
1.5 The values given in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.6 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 and health practices and determine the applicability of regulatory limitations prior to use.
