Foreword
This standard is based on GB/T 1.1-2009 given rule drafting.
This standard replaces GB/T 13480-1992 and GB/T 13480-1992 main zone "of mineral wool products compression performance test methods"
Do the following.
--- Modify the standard name;
--- Chapter 1 will expand the "scope" in the scope of the method to all insulation products;
--- Chapter 3, "Definitions" increased "by 10% compressive stress deformation" Delete "compressive load, the compression ratio limit";
--- Chapter 4, "Principle," added the relevant provisions of compressive stress at 10% deformation;
--- Chapter 6, "sample" to increase the sample, the sample status of different sizes adjusted modified to (23 ± 5) ℃ environment in adjusting at least
6h;
--- Chapter 7 increased the test temperature requirements; test methods are no longer distinguish between methods A and B;
--- Chapter 8 increase "10% compressive stress of deformation" is calculated, and the processing method different curves have been classified;
--- Increased Chapter 9, "precision";
--- Increasing the normative Appendix A "to modify the foam glass products General Test Methods."
This standard uses the translation method identical with ISO 29469.2008 "Building insulation products - Determination of compression properties."
This standard by the National Standardization Technical Committee heat insulating material (SAC/TC191) centralized.
This standard was drafted. Nanjing Fiberglass Research and Design Institute Limited, the national glass fiber product quality supervision and inspection center.
The main drafters of this standard. Hao Zheng Tao, Fang Yunwei, Madan, Cui Jun, Xu Qi, Xu Min, Huang Ying, Chen Jianming, Li Jun light.
This standard replaces the standards previously issued as follows.

Building insulation products - Determination of compression properties
1 Scope
This standard specifies the measurement sample compression performance equipment and procedures. This standard applies to insulation products can be used to determine the compressive creep test
Inspection and insulation in the short-term load testing process by compressive stress.
This method can be used for quality control, it can also be used to obtain a reference value to calculate the design value and the reference value with a safety factor.
