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 standard system of inspection and quarantine fourth floor --- personality standard that specifies the import and export of electromechanical contactors and motor starters
Inspection requirements.
