ASTM STANDARD SPECIFICATIONS

ASTM International (American Society for Testing and Materials) is one of the largest voluntary standards developing organizations in the world. They are a not-for-profit organization that provides a forum for the development and publication of international voluntary consensus standards for materials, products, systems and services. Their volunteer members represent producers, users, consumers, government, and academia from more than 140 countries. They develop technical documents that are the basis of manufacturing, management, procurement, codes and regulations for dozens of industry sectors.

ASTM volunteer members belong to one or more standards-writing committees, each of which covers a subject area such as steel, petroleum, medical devices, consumer products, nanotechnology, additive manufacturing and many more. These committees develop the more than 12,000 ASTM standards found on our site and in the 80-volume Annual Book of ASTM Standards.

You will find below summary information and links to three different standards set by the ASTM for Flat Glass manufacturing, all of which Stadium Glass proudly adheres to in our manufacturing process.

FLAT GLASS STANDARD

ASTM C1036-16    ASTM Flat Glass Standard 

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.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. 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.

HEAT-TREATED FLAT GLASS

ASTM C1048 – 12e1   ASTM Heat-Treated Flat Glass Standard 

Standard Specification for Heat-Strengthened and Fully Tempered Flat Glass

Abstract

This specification covers heat-treated flat glass – kind HS, kind FT coated and uncoated glass used in general building construction. Glass furnished under this specification shall be of the following conditions: condition A – uncoated surfaces, condition B – spandrel glass, one surface ceramic coated, and condition C – other coated glass. Flat glass furnished under this specification shall be of the following kinds: kind HS – heat-strengthened glass shall be flat glass, either transparent or patterned, in accordance with the applicable requirements, and kind FT – fully tempered glass shall be flat glass, either transparent or patterned in accordance with the applicable requirements. All fabrication, such as cutting to overall dimensions, edgework, drilled holes, notching, grinding, sandblasting, and etching, shall be performed before strengthening or tempering and shall be as specified. Requirements for fittings and hardware shall be as specified. In heat-strengthened and fully tempered glass, a strain pattern, which is not normally visible, may become visible under certain light conditions. The support system and the amount of glass deflection for a given set of wind-load conditions must be considered for design purposes. Heat-treated flat glass cannot be cut after tempering. Heat-treated glass can be furnished with holes, notches, cutouts, and bevels. The expansion fit and porosity of the ceramic coating shall be tested to meet the requirements prescribed. Specimens for evaluation of resistance to alkali and acid shall be prepared and tested to meet the requirements prescribed.

1. Scope

1.1 This specification covers the requirements for monolithic flat heat-strengthened and fully tempered coated and uncoated glass produced on a horizontal tempering system used in general building construction and other applications.

1.2 This specification does not address bent glass, or heat-strengthened or fully tempered glass manufactured on a vertical tempering system.

1.3 The dimensional values stated in SI units are to be regarded as the standard. The units given in parentheses are for information only.

1.4 The following safety hazards caveat pertains only to the test method portion, Section 10, of this specification: 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.

Coatings for Flat Glass

ASTM C1376-15    ASTM Coatings for Flat Glass Standard 

Standard Specification for Pyrolytic and Vacuum Deposition Coatings on Flat Glass

Abstract

This specification covers the optical and aesthetic quality requirements for coatings applied to glass for use in building glazing. The coatings covered are applied to the glass using either pyrolytic or vacuum (sputtering) deposition methods and are typically applied to control solar heat gain, energy performance, comfort level, and condensation and enhance the aesthetic of the building. This specification groups coated glass according to application. These groups are: vision, spandrel/nonvision, and overhead. Coated flat glass furnished under this specification shall be of the following kinds: Kind CV; Kind CO; and Kind CS.
