Test method for rock wool shear strength

Rock wool shear strength test method:

According to the provisions of GB 32382, the double test piece method. The transverse direction refers to the width direction of the rock wool strip. When making the sample, the length direction of the sample is the width direction of the rock wool strip, the width direction of the sample is the length direction of the rock wool strip, and the thickness direction of the sample is the thickness direction of the rock wool strip. The length of the sample is (200±1) mm, the width is (100±1) mm, and the thickness is (60±1) mm. When the width of the rock wool strip is less than 200 mm, the actual width is the length of the sample, and when the thickness of the rock wool strip is less than 60 mm, the actual thickness is the thickness of the sample. The number of samples is 5 pieces.
