DIN SPEC 18198:2019-12

This topic has been submitted as a request for the development of a DIN SPEC according to the PAS procedure. The application is currently being examined. DIN SPECs in accordance with the PAS procedure are developed within workshops set up on a temporary basis. This document will be developed and approved by the authors who will approve the business plan. This DIN SPEC (PAS) will provide guidelines for the reproducible evaluation of optical anisotropic effects in thermally toughened flat glass. Quality classes, which are based on different test methods, on specified evaluation criteria and on effects, which result from external factors at the place of installation, will be specified.The evaluation criteria are also applicable to non-monolithic glazing, but as additional effects, which cannot be entirely quantified, can occur, this DIN SPEC (PAS) will be restricted to monolithic structures.
