Foreword

This standard reference ASTMC795-2003 "austenitic stainless steel covered with a heat insulating material norms" and ASTMC692-2006 "Test Method for Evaluation insulation cracking of austenitic stainless steel external stress corrosion." This standard replaces GB/T 17393-1998 "austenitic stainless steel covered with a heat insulating material specification." This standard compared with the original standard, the main technical changes as follows. --- Added "Standard Test Method for insulation material for stress corrosion cracking of austenitic stainless steel external impact assessment", as Appendix A; --- Increasing the "insulation flooding measurement of pH," as Appendix B. Please note that some of the content of this standard may involve patents, the issuing authority of this standard should not bear the responsibility to identify these patents. The Standard Appendix A and Appendix B are normative appendix. The standard proposed by China Building Materials Federation. This standard by the National Standardization Technical Committee heat insulating material (SAC/TC191) centralized. This standard is drafted by. Nanjing Fiberglass Research and Design Institute. Participated in the drafting of this standard. Owens Corning (China) Investment Co., Ltd., Deqing County, Zhejiang Pu Sen Refractories Co., Ltd., West Newcastle (Guangzhou) Co., Ltd. Building Materials. The main drafters of this standard. Shad Ren, Yang Chunying, Gedui Shi, Wang Zhi. This standard superseded standard previously issued as follows. --- GB/T 17393-1998. Austenitic stainless steel covered with a heat insulating material specification

1 Scope

This standard specifies the austenitic stainless steel covered with insulating material (hereinafter referred to as heat insulating material) terms and definitions, general requirements, requirements, Test methods, inspection rules, and packaging, labeling, transport and storage. This standard applies to fibrous insulation materials, including aluminum silicate wool, rock wool, slag wool, glass wool and its products, it must also apply to other Thermal materials, such as calcium silicate, complex silicates, asbestos foam, foam, foam rubber and plastics.
