→According to GB/T7019-2014 Test methods for fiber cement products, uniform loading, control the loading speed in 10s ~ 30s until the specimen breaks and read the maximum failure load.
→If rectangular specimen is used, the flexural load can be got in longitudinal and transverse directions and the average value of the two measurement results is the representative value.
→The specimen for transverse test should be use the whole tile and the specimen for longitudinal test should be taken from the tile after transverse test.
