SN/T 1431.5-2011Rules for the inspection of low-voltage electrical apparatus for import and export. Part 5: Low-voltage fuses (English PDF)

Foreword

SN/T 1431 "Importers and low-voltage electrical inspection procedures" series of standards is divided into five parts.

--- Part 1. General requirements

--- Part 2. Household and similar circuit breakers for overcurrent protection

--- Part 3. Household and similar residual current operated circuit breaker

--- Part 4. Electromechanical contactors and motor starters

--- Part 5. Low voltage fuses this is Part 5 SN/T 1431 "Importers and low-voltage electrical inspection procedures" series of standards.

This section based on GB/T 1.1-2009 write drafted.

Some of this section may involve patents, this part of the release mechanism does not assume the responsibility to identify these patents.

The partial replacement of SN/T 1030-2001, compared with the SN/T 1030-2001 The main changes are as follows.

--- Examine the contents of the deleted original packaging procedures, shape and installation dimensions, plug inspection and testing of semiconductor devices;

--- Increasing the consistency test project, assembly quality inspection;

--- Modify the contents flag check, insulation test is amended as insulation and isolation suitability verification;

--- Table 2. visual inspection of the surface of the product failed to Category B, the fuse characteristics test failure unified classification A;

--- Increased content inspection and supervision mode and test mode.

This section proposed and managed by the National Certification and Accreditation Administration Committee.

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 low voltage fuses.

Low-voltage electrical inspection of import and export Part 5. Low voltage fuses

1 Scope

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

This section applies to the rated voltage not exceeding 1000V, DC, or no more than 1500V, and is equipped with no less than the rated breaking capacity 6kA enclosed low-voltage current-limiting fuses fuse test.

This section does not apply to small fuse test.
