Fireproof coatings tester chamber method
Standards
GB 14907—1994、GB 14907—2002、ETAG：2006、BS 8202:1992:2
Sample making
1. The test plate of the fireproof coating tester (small chamber method) is made of birch five-layer plywood conforming to GB738-75 "broadleaf wood plywood", its size is 300mmx150mmx5mm, and the surface of the sample should be smooth and smooth, without joints and other defects.
2. before the test board is coated with fireproof paint, the state should be adjusted to constant at the temperature of 25±1℃ and the relative humidity of 60%——70% (the weight change of 24h interval is not more than 0.1%)。
3. according to the coating ratio of 200——250g/m2 (thick paste coating allows to increase to 500g/m2) to test the fire retardant coating evenly covered on the surface of the test plate and around, when the need for multiple coating, the interval between two times should be 24h.
The finished specimens shall be adjusted to constant weight according to the condition state specified in 2 articles, and ten specimens of each fireproof coating shall be prepared.
