Introduction

"Inspection of import and export motors Part 4. single-phase asynchronous motor" motor import and export inspection work in accordance with the import and export of single-phase Induction motor testing play a guiding and regulating.

With China's accession to the World Trade Organization (WTO) and the "People's Republic of China Import and Export Commodity Inspection Law" and its implementing regulations amended Import and Export Commodity Inspection, great changes occurred in work mode. To adapt to the situation and change, the State Quality Supervision, Inspection and Quarantine administrations group Organizations established inspection and quarantine standards.

This part belongs to the standard system of inspection and quarantine fourth floor --- personality criteria for the characteristics of single-phase induction motor, provides for import and export single Phase asynchronous motor special inspection requirements.

Import and export inspection of motor Part 4. single-phase induction motor

1 Scope

SN/T 3237 provisions of this part of the sampling, testing and qualification of import and export safety performance single-phase asynchronous motors determination method.

This section applies to the rated voltage of 330V and below, rated frequency 50Hz, 60Hz single-phase AC power (including mains power and Inverter power) test powered general purpose single-phase AC induction motor (hereinafter referred to as "motor") of. 330V or more electric Machine can be performed with reference to this section.

This section does not apply to motor test explosion motors, marine motors and other special purposes.
