ÖNORM EN 356

This European Standard specifies requirements and test methods for security glazing designed to resist actions of force by delaying access of objects and/or persons to a protected space for a short period of time. This standard classifies security glazing products into categories of resistance to actions of force. In this European Standard, the categories of resistance have not been assigned to special applications. Selection of categories should be made by the user for every individual case, after consulting an expert if necessary. NOTE 1: Security glazing products should be installed in a frame which can give appropriate resistance to attack and which also provides a suitable support for the security glazing product. NOTE 2: Cut-outs and holes in security glazing products should be avoided where possible, as these can affect the resistance of the product. This European Standard deals with mechanical resistance to attack only. Other properties can also be important, for which separate standards will be prepared.
