Falling-weight test small area indenter GB 50009 Load code for the design of building structures 3 Terms and definitions The terms and definitions as defined in GB/T 18378 AND the following terms and definitions apply to this document. 3.1 Homogeneous thermoplastic polyolefin waterproofing sheets It refers to the thermoplastic polyolefin waterproofing sheets that do not employ an inner reinforcing material or a backing material. 3.2 Thermoplastic polyolefin waterproofing sheets backed with fabric It refers to the thermoplastic polyolefin waterproofing sheets which compound the fabric such as polyester nonwoven fabric at the lower surface. 3.3 Thermoplastic polyolefin waterproofing sheets with internally reinforced fabric It refers to the thermoplastic polyolefin waterproofing sheets which is reinforced with polyester or fiberglass meshes in the middle of the sheet. 6.4 Appearance Visual inspection. 6.5 Tensile performance The test sample size of type L and P product is 150 mm × 50 mm; PERFORM test in accordance with the method A of GB/T 328.9-2007; the fixture spacing is 90 mm; the elongation is calculated using the 70 mm marking line spacing; the type P elongation is taken as the elongation L at the maximum tension, AND the type L elongation is taken as the elongation at fracture. If the sample does not fracture when the product testing machine travels to its end, CHANGE the fixture spacing to 50 mm and the marking line spacing to 30 mm; PERFORM test again; AND all the tensile performance tests of the same sample shall be made using the same method. The type H is tested in accordance with the method B in GB/T 328.9-2007, it uses the dumbbell type I test piece which complies with GB/T 528, AND the tensile speed is (250 ± 50) mm/min. The arithmetic mean of the 5 test samples in the longitudinal or transverse direction is calculated as the test result. 6.6 Heat treatment dimensional change rate PERFORM test in accordance with GB/T 328.13 in the 80 °C ± 2 °C blast oven; it is not allowed to stack them; AND it is remained at this constant temperature for 24 h. TAKE it out; PLACE it at the standard test conditions for 24 h; MEASURE the length. 6.7 Low temperature bending performance PERFORM test in accordance with GB/T 328.15. 6.8 Water tightness PERFORM test in accordance with the method B of GB/T 328.10-2007; USE the cross metal slotted plate, AND the pressure is 0.3 MPa, which is maintained for 2 h. 6.9 Impact resistance PLACE the perforator on the surface of the test sample; LET the steel ball at the lower end of the punch head position at the center of the test sample; MAKE the spherical surface in contact with the test sample. ADJUST the hammer to the specified drop height of 500 mm and POSITION it. LET the hammer fall down freely to impact the punch head at the test sample surface; TAKE the sample out; CHECK whether the test sample is perforated; TEST 3 samples in total. When there is no obvious perforation, USE the device as shown in Figure 1 to perform water tightness test against the sample. PLACE the round glass tube vertically at the center of the test hole of the sample; USE the sealant to seal the gap between the glass tube and the sample. PLACE the test sample on a 150 mm × 150 mm filter paper; PLACE the filter paper on a glass plate; ADD the stained water into the glass tube; LET it stand for 24 h; CHECK the filter paper; AND if there is color change or water traces, it indicates that the sample is perforated. 6.10 Static load resistance PERFORM test in accordance with the test method A in GB/T 328.25-2007; USE the 20 kg load. 6.11 Peel strength... .......
