41、specific process control conditions. 4.2.2.1 Safety in the case of fire - Resistance to fire Fire resistance shall be determined and classified in accordance with EN 13501-2. Note: EN 357 may be used as a classification reference specific to fire resistant glazed elements. 4.2.2.2 Safety in the case
42、 of fire - Reaction to fire Reaction to fire shall be determined and classified in accordance with EN 13501-1. Borosilicate glass products are products/materials that do not require to be tested for reaction to fire (e.g. Products/materials of Classes A1* according to Commission Decision 96/603/EC,
