The hottest spot check of non flame retardant and

State Administration of market supervision: 5.2% of non flame retardant (Fire-resistant) wires and cables were unqualified in 2018

[cable news] on January 11, 2019, the State Administration of Market Supervision issued the notice of the State Administration of market supervision on the special spot check of the national supervision on the quality of non flame retardant (Fire-resistant) wires and cables in 2018. According to the notification, according to the provisions of the product quality law of the people's Republic of China and the deployment of special rectification of wires and cables, in 2018, the State Administration of market supervision organized a special spot check of national supervision on non flame retardant (Fire-resistant) wire and cable products

it is reported that 349 batches of products produced by 349 enterprises in 13 provinces (autonomous regions and municipalities directly under the central government) were sampled. Among them, 18 batches of products produced by 18 enterprises were detected to be unqualified, and the unqualified rate of samples was 5.2%

according to the production scale of enterprises, the large, medium, small and micro enterprises selected accounted for 0.9%, 9.5%, 67.0% and 22.6% of the total number of enterprises selected, and the qualified rate of product sampling was 100%, 97.0%, 95.7% and 91.1% respectively

according to the type of products, 125 batches of XLPE insulated cables, 217 batches of PVC insulated wires and cables, and 7 batches of general rubber sheathed flexible cables and wires were randomly selected. An exciting news came from the products, and the qualified rates were 88.8%, 98.2% and 100% respectively

this special spot check focuses on the inspection of 26 items in four aspects: the structural size, electrical performance, mechanical and physical performance, and the performance of finished cables of non flame retardant (Fire-resistant) wires and cables. After inspection, the main quality problems of unqualified products are concentrated in four aspects: structural size, electrical performance, mechanical and physical properties, wider market prospects, and the performance of finished cables

in terms of structural dimensions, 349 batches of Smartech products were tested for the thickness of the thinnest part of the insulation, of which 1 batch was unqualified, and the project qualification rate was 99.7%

in terms of electrical performance, 349 batches of products sampled this time have been tested for conductor resistance, of which 1 batch is unqualified, and the project qualification rate is 99.7%

in terms of mechanical and physical properties, the insulation shrinkage test items of 114 batches of products were tested, of which 6 batches were unqualified, and the qualification rate of the items was 94.7%

in terms of finished cables, 126 batches of products were tested for bending, of which one batch was unqualified, and the project qualification rate was 99.2%
