Homogeneous sheets refer to the water-proof sheets using polymer composite

materials as main materials, whose cross-sectional structure of each part is the

same.

3.3 Self-adhesive sheet

Self-adhesive sheets refer to the water-proof sheets compositing a layer of self-

adhesive material and an isolation protective layer on the surface of each

polymer sheet to improve the adhesive properties between self-adhesive sheet

and base layer, whose cross-sectional structure of each part is the same.

3.4 Special-shaped sheet

Special-shaped sheets refer to the water-proof (drainage) sheets using polymer

composite materials as main materials, whose surfaces are continuous convex

and concave shells or in specific geometric shapes after processed by means

of special technologies.

3.6 Composite strength

It refers to the composite strength BETWEEN the protective or reinforcing layer

on the surface AND the core of the composite sheet, expressed as MPa.

3.7 Section area of drainage water

It refers to the drainage cross-sectional area formed by the shell-shaped

protrusion on per linear meter of cross section of the special-shaped sheet

(waterproofing and drainage protective plate), expressed as cm2.

4.1 Classification of the sheets

As shown in Table 1.

4.2 Product markings

4.2.1 Marking method

MARK the products according to the following sequence. Moreover, it is allowed

to add markings as required.

5.1 Specifications

The specifications and dimensional tolerances of the sheets are shown in

Tables 2 and 3.Special specifications shall be agreed upon by the supplier and

demander.

5.2 Appearance quality

5.2.1 The sheet surfaces shall be smooth without any defects affecting the

service properties, such as impurities, mechanical damages, creases,

abnormal adhesion, etc.

5.2.2 Under the condition of not affecting the utilization, the defects on the

sheet surfaces shall conform to the following provisions.

5.2.3 There shall be neat edges without any defects on the surfaces of the

special-shaped sheets, such as cracks, holes, adhesion, bubbles, scars and

other mechanical damages.

5.3 Physical properties

5.3.2 Composite sheets

5.3.2.1 The physical properties of the composite sheets shall conform to the

provisions of Table 5.

5.3.5 Material with point (strip) adhesion sheets

The main materials of the material with point (strip) adhesion sheets shall

comply with the requirements of relevant categories in Table 4.The properties

of the adhesion positions shall conform to the provisions of Table 8.

6.1 Determination of the sheet dimensions

6.1.1 Length and width

USE a steel tape for measurement. ACCURATE to 1mm. DETERMINE the

widths at three points on both ends in the longitudinal direction and near the

center. TAKE the arithmetic mean value. For the length determination, TAKE

the shortest part of the full length of each roll.

6.1.2 Thickness

USE a thickness gauge with a division value of 1/100mm, a pressure of (22 ±

5) kPa, a measured foot diameter of 6mm for measurement. The measuring

points are shown in Figure 1.CUT off 300mm from the end.

6.1.3 Shell height of the special-shaped sheet

USE a Vernier caliper with an accuracy of 0.02mm for measurement. CUT off

the test piece with a length of greater than or equal to 300mm from the end.

CUT a 100mm long test piece afterwards. The measuring points shall be same

as Section 6.1.2.ENSURE that the shell in the cutting position is intact. TAKE

the arithmetic mean value of five shell heights as measurement result.

6.2 Appearance quality

USE visual observation and measuring tools for the appearance quality

inspection of the sheets.

6.3 Determination for the physical properties of the sheets

6.3.2.1.4 Type I test pieces shall be applied to the tension test. During high-

temperature (60°C) and low-temperature (-20°C) tests, if Type I test pieces are

not applicable, it is allowed to use Type II test pieces instead. PREHEAT or

PRECOOL the test pieces at specified temperature for 1h.
