(A) monitoring content. Guangdong Provincial Administration for Industry and Commerce commissioned Maoming City, Guangdong Province Quality Supervision and Testing of switch socket commodity circulation in the province quality monitoring. Paragraph 92 sockets (including the converter), collected a total of 32 sales units 38 paragraph switch, involved in the production unit 83. The sampling was based primarily on household and similar purposes plug and socket - Part 1: General requirements "(GB 2099.1-2008)," household and similar purposes plug sockets - Part 2: converter special requirements "(GB 2099.3-2008 ), "Household and similar single-phase plug and socket types, basic parameters and dimensions (GB 1002-2008)," household and similar fixed electrical installations - Part 1: General requirements "(GB 16915.1-2003) standard socket (with converter) project of the Commodity Inspection protection against electric shock, soft cable and its connection (mobile outlet), grounding, heat, electric strength, insulation resistance, creepage distance, clearance, dimensional inspection, fire resistance, resistant to moisture, signs, etc.; switch Commodity Inspection project electric strength, insulation resistance, temperature rise, heat, flame, creepage distance, clearance, moisture, protection against electric shock, high capacity, mechanical strength, signs and other items.

Monitoring the use of national supervision and sampling inspection standards "and Part 4: Sampling procedures for inspection and claimed that the level of quality assessment procedures" (GB / T 2828.4-2008) implementation, verification of the general provisions of the same manufacturers of the same (or the same brand) nominal types of switches, sockets goods, select the LQR = 0, n = 2, l = 0 sampling plan the implementation of sampling, and in accordance with the claimed quality level (DQL) to 2.5 pairs of verification of the overall judgment. Sampling failed to determine the samples of the same nominal producer, the same model switch socket verification of the overall failure.

(B) monitoring results. 68 models by the 130 models of commodity inspection, monitoring overall commodity verification failed, the switch goods 9 59 models of the goods of the socket (with converter), The remaining 62 samples taken not found unqualified.

Second, the quality analysis

Monitoring switch socket product failure: temperature rise, heat, high capacity, soft cable and its connection, grounding, electrical strength, dimensional inspection, marking, etc.
