Some standard content:
Preface
Article 4.3 of this standard is mandatory, and the rest are recommended. GB12953—2003 | The degree of consistency of "Requirements for Chlorinated Polyethylene (PE-C) Plastic Roofing Membranes and Plastic Sealing Membranes" is non-equivalent
The main difference between this standard and DIN16736 and DIN16737 is: the addition of no composite layer Class chlorinated polyethylene waterproofing membrane: divided into type 1 and type Ⅱ according to performance;
-L type I product has a break elongation and low temperature bending property higher than DIN16736 requirements; a W type Ⅱ product The tensile force is lower than the requirements of DIN16737, the elongation at break is expressed by the elongation between clamps, and the low bending property is higher than the requirements of DIN16737;
—the water vapor permeability coefficient is cancelled,
This standard replaces GB12953-1991 "Fluorinated Ethylene Waterproof Membrane", the main difference between this standard and GB12953-1991 is that the product models are divided into type I and type II (3.1 in the 1991 version; 3.1 in this version): 1. Added single-sided fiber seam composite , Category of reinforcing joints in fabrics (3,1 in this edition): For single-sided fiber composites and reinforced coils in fabrics, the unit width tensile force is used instead of tensile strength, and the breaking elongation between them is used instead of the breaking elongation between the marking lines. rate, the shape of the specimen was changed (5 in the 1991 edition; 5.5.3 in this edition); a pair of impermeability and adhesion test methods were adjusted, and specific requirements were given for the durability test method (1991 edition) 5; 5.10, 5.13 of this edition)

Multiply the average length by the average width to obtain each roll. The area of ??the material. If there is a joint, it is calculated by subtracting 150mm from the sum of the measured lengths of the two sections. 5.3.2 Thickness

Use a thin sharp blade along the width direction of each sample to cut a strip of approximately 50mm × 2mm perpendicular to the surface of the sample. Test strip, be careful not to deform the cross section of the test strip (section in the thickness direction). Place the cut surface of the test strip upward on the sample stage of the reading microscope, and read the thickness of the chlorinated vinyl layer of the roll (excluding the fiber layer). For products with embossed patterns on the surface, calculate the thickness based on the tangent position of the outermost end of the pattern. , measure 4 points on each test strip, the thickness is expressed as the average of 20 values ??from 5 test strips, and the smallest single value among the 20 points is reported. 5.4 Appearance
