ASTM WK72386

    New Practice for Weathering and Evaluation of Laminated Glass

    (What is a Work Item?)

    Developed by Subcommittee: C14.08 | Committee C14 | Contact Staff Manager


    1. Scope

    1.1.This practice is intended to cover procedures for the exposure of laminated glass materials to natural and accelerated weather. 1.2.This practice is limited to the method by which the material is to be exposed and the general procedure to be followed. It is intended for use with finished articles of commerce as well as with all sizes and shapes of test specimens. 1.3.Means of evaluation of the effects of weathering will depend on the intended use for the test material. 1.4.This practice is meant to examine color and transmittance changes of the polymer and does not evaluate edges for blush or edge stability. 1.5.The values stated in SI units are to be regarded as the standard. 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.

    Weathering testing and evaluation as described in this document has been used in the glass industry as referenced in ANSI Z97.1 since at least 2005 The tests have been documented and specified as part of third-party certifications and acceptance of interlayer products for compliance. The method and evaluation have not been documented in an ASTM referenceable form. The approval of this test method resolves that issue and makes the test method more accessible to the users and general public for proper referencing. The key drivers for this to become an ASTM standard is 1.) simplify the weathering requirements in ANSI Z97.1 document by allowing a reference to an international standard versus inclusion of extraneous test verbiage and 2.) provide an avenue for weathering experts outside of the direct ASC committee to comment on and recommend new and advanced methods as they occur with regard to weathering and durability exposures. This standard does not evaluate edges for blush or edge stability.

    The title and scope are in draft form and are under development within this ASTM Committee.
