Foreword

This standard and ISO 9933-1995 "fiber-reinforced cement products for roofing and cladding corrugated or asymmetrical section sheets and fittings" ISO 9383-1995 "fiber cement roofing products with a small corrugated or asymmetrical section sheets and fittings," the non-equivalent.

This standard replaces GB/T 9772-1996 "asbestos cement Bowa and Jiwa." the main difference compared with the standard GB/T 9772-1996 as follows.

--- Modify the standard name;

--- Define the scope of the standard;

--- Expanding the reinforcing fiber varieties;

--- Of Bova wave height reclassified with international standards (formerly standard 3.3, the new standard 3.3);

--- Shape and size deviation indicator has been modified to increase the difference between the diagonal project;

--- Bending strength according to three intensity levels, cancel superior products, first-class products, qualified quality level (formerly standard 3.2, the new standard 3.2);

--- Test method of GB/T 7019-1997 "Test method for fiber cement products" implementation of the provisions.

The standard proposed by China Building Materials Federation.

This standard by the National Standardization Technical Committee cement products (SAC/TC197) centralized.
