[Fire-rated roller shutter] Acceptance and testing by these standards
RHidoor’s fire-rated roller shutters are already widely used, especially in large supermarkets, commercial towers, and underground garages. The performance is solid. Proper makers only install products that pass strict testing. So an installed fire-rated roller shutter must be accepted and tested by these points.
The shutter goes through the fire-door heating test per national standard GB12955-2008. If it meets all of the following, it counts as grade A. If it meets only some, it counts as grade B.
Standard test:
1. No harmful deformation, fall-off, or damage from the fire test on the door.
2. No flame through the solid unheated face, and no harmful cracks or holes.
3. In the heating test, no part of the sample bows or deflects more than half the leaf thickness.
4. In the heating test, no burning flame on the unheated face.
5. The highest temperature on the unheated face stays under 960 degrees.
Acceptance criteria:
1. Observe and check the product certificate and on-site acceptance record. Is the frame firmly installed? Does the position and opening direction match the design? Do the count, position, embed, and connection of the embedded iron parts match the design?
2. Check the basic items. Pass: closes tight, opens and closes freely, no deformation, no warp; soundproof door seals well, auto-close is quick. Good: closes tight, opens and closes freely, no block, no rebound, no deformation or warp; soundproof door seals well; fire door auto-close is quick.
3. Check the accessories. Pass: complete, firmly installed, correct position, opens and closes smoothly and fits use. Good: complete, firmly installed, correct and straight position, opens and closes smoothly, fits use and looks good.
