ANSI 297.1-2015 pdf free download.For safety glazing materials used in buildings一 safety performance specifications and methods of test.
The Accredited Standards Committee (“ASC”) Z97 and its Secretariat, currently the Glazing Industry Secretariat Committee, have developed this recommended safety performance specification and test method for glazing materials through a consensus standards development process the American National Standards Institute has approved. This process brings together volunteers representing varied view points and interests to achieve consensus on safety related issues. While the ASC Z97 and its Secretariat administer the process in accordance with ANSI established rules designed to promote fairness in the development of consensus, neither the ASC Z97 nor its Secretariat independently tests, evaluates, or verifies the accuracy of any information or the soundness of any judgments contained within the document, ANSI Standard Z97.1 . The ASC Z97, together with its members, affiliates, and its Secretariat, expressly disclaim and shall not be liable for any personal injury, property or other damage of any nature, whether special, indirect, consequential, or compensatory, directly or indirectly resulting from the publication, use of, or reliance upon this document, whether based upon breach of contract, breach of warranty, tort (including negligence), strict liability, or otherwise, even if advised of the possibility of such damages. The foregoing negation of damages is a fundamental element of the use of the information and data contained herein, and this information and data would not be developed, compiled, and forwarded by ASC Z97 to ANSI without such limitation. The ASC Z97, together with its members, affiliates, and its Secretariat, also make no guarantees or warranties, express or implied, including without limitation, any and all warranties concerning the accuracy or completeness of the information in the document, its fitness or appropriateness for a particular purpose or use, its merchantability, and its non-infringement of any third party’s intellectual property rights.
asymmetric material: Glazing in which component layers of its construction makeup are different in thickness, kind, type or pattern texture about its interlayer and/or central plane surface. bent glass: Flat glass that has been shaped while hot into a form that has curved surfaces. bubble: A visible gas pocket in the interlayer material or in the plastic glazing sheet material, or between the interlayer and another layer of glass or plastic glazing sheet material. cracking: The visible breaking, splitting or fissuring, either partially or completely through the thickness of an individual layer of material. crack-free particle: A portion of a broken test specimen that is determined by identifying the smallest possible perimeter around all points in the portion of the broken test specimen, always passing along un-separated cracks or exposed surfaces. crazing: The visible breaking, splitting or fissuring of a material, typically patterned with a network of fine lines that do not penetrate through the thickness of an individual layer of material. delamination: A condition in which one of the glass or plastic glazing sheet material layers loses its bond to an interlayer and separates physically. discoloration: A visibly noticeable chemical or process induced color deviation in the appearance of a material. laminated glazing: A manufactured assembly consisting of at least one sheet of glass bonded to at least one other sheet of glass or plastic glazing material with an organic interlayer. Note: when broken, numerous cracks appear, but glass fragments tend to adhere to the interlayer. See ASTM C1 1 72 for additional information.
4.4 Specimens for Impact Tests For impact test (see section 5.1 ) of any safety glazing material, four specimens, each of the thickness and size described in sections 4.2 and 4.3 respectively, shall be required. If the test specimens are of an asymmetric material, two shall be impacted from each side. For impact test of safety glazing materials after aging (see section 5.4.3) as used in indoor applications only, four specimens, each of the thickness and size described in sections 4.2 and 4.3 respectively, shall be required. If the test specimens are of an asymmetric material two shall be impacted from each side.
