China: New GB standard for refrigeration and air-conditioning

 

China has published a new standard National Standard of the P.R.C., Refrigeration and air-conditioning equipment—Safety technical specification.

It specifies the general safety requirements for refrigeration and air conditioning equipment, and the safety technical requirements for all aspects of the life cycle including materials, design, manufacturing, installation, use, and maintenance.

The standard does not apply to refrigeration and air conditioning equipment used in automotive air conditioning and marine conditions.

The standard contains the following sections:

1 Scope

2 Normative reference documents

3 Terms and Definitions

4 General principles

5 Materials

6 Design

7 Manufacturing, inspection and acceptance

8 Installation, operation and maintenance

Appendix A (Informative) Potential Hazards of Refrigeration and Air Conditioning Equipment

Appendix B (Normative) Additional requirements for refrigeration and air-conditioning equipment using ammonia as refrigerant

Appendix C (Normative) Specific requirements for heat transfer fluids in refrigeration and air conditioning equipment

Appendix D (Normative) Refrigerant filling requirements for refrigeration and air conditioning equipment production lines using flammable refrigerants
