How is the fire resistance for insulated rock wool panel?
1. Integrity: according to GB / T 9978-2008.1, 10.2, 2 standards
Test result: fire rated 54min, the back surface of the rock wool test piece has no flame, no cotton pad.
2. Thermal insulation:
According to GB / T 9978-2008.1, 10.2, 2.3; the technical index loses heat insulation, the average temperature rise of the back fire surface of the test piece exceeds the initial average temperature by 140 ℃; the temperature rise of any point exceeds the initial average temperature by 180 ℃.
Test result: after 54 min, the average temperature rise of the back surface of the test piece is 89 ℃, and the maximum temperature rise is 190 ℃.
That is rock wool sandwich panel fire resistance conclusion: 54min
