Foreword

Flame-retardant and fire-resistant wires and cables, including halogenated, halogen-free, and low-smoke products, have been produced and used in China for more than ten years, which is of great significance to fire safety. However, because there is no international standard or national standard, the product name, model, technical requirements, and test methods are quite confusing, and some are inconsistent with international requirements. This standard is formulated to unify domestic production and use, and to meet the needs of international trade and economic and technological exchanges.
Taking into account the requirements of flame retardant and fire resistance can cover almost all wire and cable products, and to achieve this purpose generally does not need to change the structure of the wire and cable, but to change the materials used. Therefore, instead of adopting a method of formulating product standards one by one, this general rule is formulated, and requirements for combustion characteristics such as flame retardant and fire resistance are different from the current ordinary product standards. Recommended flame retardant or refractory materials are recommended, and corresponding The mark is added to the front of the common product model to distinguish it from the common product.
In this standard, the test methods and performance requirements for halogen-free, low-smoke, flame-retardant, and fire-resistant properties adopt the following latest versions of international standards:
IEC 60331: 1999 Line or fiber optic cable integrity test under flame conditions
IEC 60332: 2000 Fire test of electric or optical cables under flame conditions
IEC 60754: 1997 Test Method for Gas Released from Combustion of Materials from Electric or Optical Cables
IEC 61034: 1997 Determination of smoke density of cables or optical cables burning under specific conditions
This general rule can be used directly as a product standard. If a single-line product standard is to be prepared, the relevant content must comply with the provisions of this general rule.
Appendix A, Appendix B and Appendix C of this standard are informative appendices.
This standard is the first national standard.
This standard was proposed by the China Electrical Equipment Industry Association.
This standard is under the jurisdiction of the National Wire and Cable Standardization Technical Committee.
