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 requirements for the import and export inspection trip switches. Low-voltage electrical inspection of import and export Part 7. limit switch

1 Scope

SN/T 1431 This section provides the determination Importers limit switch sampling, testing and results. This section applies to AC voltage to 1000V (frequencies not exceeding 1000Hz), 600V DC voltage to the circuit, as a control System, limit, positioning, stroke, signal or program conversion with import and export inspection trip switch. This section does not apply to AC or DC voltage of less than 100V products.
