JG/T 396-2012Non-load bearing fiber-reinforced-cement sheet for exterior wall (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard uses the redrafted law to amend the use of ISO 8336.:2009 "Fiber cement slab - Product Specifications and Test Methods." With ISO 8336. The main technical differences in 2009 are as follows.

--- Increased diagonal size allowable deviation, surface roughness, apparent density, water absorption and coating quality requirements.

--- Increased humidity deformation, clearly less than or equal to 0.07%.

--- Modify the durability index, unified in the ISO 8336.:2009 frost resistance of 100 times, modified to climatic zones. cold areas 100 times, 75 times in the cold area, 50 in the hot summer and cold winter area and 25 in the hot summer and warm winter area.

--- Modify the physical and mechanical properties of the coating test state, in the ISO 8336.:2009 plate physical and mechanical properties can be coated with the test, but the test results should be marked with a coating test; combined with the quality of the domestic coating, clearly amended as follows.

Fiber-reinforced concrete slabs that are tested for their physical properties and mechanical properties shall not be treated with water repellent or painted.

--- Remove the full state of flexural strength greater than or equal to 4MPa lower mechanical performance level.

This standard Appendix B using the redrafted method is not equivalent to the use of JISA5422.:2008 "fiber reinforced cement wall panels." this standard proposed by the Ministry of Housing and Urban Standard and Design Institute.

This standard by the Housing and Urban-Rural Construction Products and Components Standardization Technical Committee.

1 Scope

This standard specifies the external wall with non-load-bearing fiber reinforced cement board (hereinafter referred to as fiber reinforced cement board) terms and definitions, classification, specifications and marking, general requirements,, test methods, inspection rules, signs and certificates, transport, packaging and storage.

This standard applies to non-load-bearing reinforced concrete wall cladding, panels and linings.
