Introduction

"Importers and low-voltage electrical inspection of" low-voltage electrical products import and export inspection work basis, import and export of low-voltage electrical products Inspection play a guiding and regulating.

With China's accession to the World Trade Organization (WTO) and the revised "People's Republic of China Import and Export Commodity Inspection Law" Import and Export Commodity Inspection Test mode has undergone great change, to adapt to changes in the situation and to meet the actual needs of inspection and quarantine work, Inspection and Quarantine of the competent Inspection and quarantine departments to establish a standard system.

This part belongs to the inspection and quarantine standards on the third floor --- categories common standard specifies the general requirements for the import and export of low-voltage electrical inspection.

Low-voltage electrical inspection of import and export Part 1. General requirements

1 Scope

This section provides the import and export of low-voltage electrical sampling, testing and the results of determination.

This section applies to AC 50Hz (or 60Hz), rated voltage not exceeding 1000V AC or DC circuits not exceeding 1500V Play-off, protection, control or regulation of electrical test. Rated AC voltage 1000V ~ 1200V appliances can refer to this section carried out.

Low-voltage electrical products covered by the national standards in this section in Appendix A.
