48、tion shall be related to the complete glazed element which incorporates the glass products and all given dimensions and tolerances. The classification values are those obtained by the tested fire resistant glazed elements containing the glass product in accordance with EN 13501-2. To achieve classif
49、ication, an appropriate frame containing the glass product and designed by the sponsor, can be used for the fire test. NOTE The classification obtained with this standard structure does not mean that the glass product, used in a different frame, offers the same fire resistance as it does in the tested frame.
