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...
