0 Introduction
This Rule is prepared basing on safety risks and certification risks of low voltage switchgear and specifies the basic principles and requirements for implementing compulsory product certification of low voltage switchgear.
This Rule is used jointly with general applicable rules issued by CNCA, like "Implementation Rules for Compulsory Product Certification - Classification Management of Manufacturers, Certification Mode Selection and Determination", "Implementation Rules for Compulsory Product Certification - Application of Manufacturer Inspection Resources and Other Certification Results", "Implementation Rules for Compulsory Product Certification - General Requirements for Factory Inspection".
The certification body shall, in accordance with the requirements of general applicable rules and this Rule, formulate certification implementation rules which shall also be implemented jointly with general applicable rules and this Rule.
Manufacturers shall ensure that their certified products always meet the requirements of certification and applicable standards.
1 Application Scope
This Rule is applicable to low voltage switchgear, including power switchgear set having 1000V AC rated voltage and 1000Hz or less frequency, busbar trunking system (busway), distribution board, assemblies for construction sites (ACS), assemblies for power distribution in public networks and reactive power compensator.
The application scope adjustment caused by changes, e.g. laws & regulations or relevant product standards, techniques, and industrial policies, shall be subject to CNCA announcement.
2 Terms and Definitions
In this Rule, design appraisal, a non-experimental verification measure, refers to methods of validation comparison and validation evaluation to prove that products comply to the certification standards.
