General Administration of quality inspection of 83 batches of substandard quality detection cable
9 Bulletin of wire and cable products State Quality Inspection Administration of quality and the linkage supervision and inspection results, provided 83 batches of the product does not meet the criteria of.
The fourth quarter of 2013, a total sample of Hebei, Liaoning, Jiangsu, Zhejiang, Anhui, Shandong, Henan, Hubei, Guangdong, Sichuan, Xinjiang and other 11 provinces, autonomous regions 935 enterprises produced 936 batches of wire and cable products. On the basis of GB/T5023.5-2008 "rated voltage 450/750V and below PVC insulated cables - Part fifth: flexible cable (cord)," JB/T8734.3-1998 "rated voltage 450/750V and below PVC insulated cables and wires and cords of third parts: the connection with a soft wire", JB/T8734.3-2012 "rated voltage 450/750V and below PVC insulated cables and wires and cords of third parts: the connection with standard software wire and cable" and other requirements, to the wire and cable products, soft PVC insulated wire and cable products average thickness of insulation, insulation thinnest thickness of sheath, sheath, the average thickness of the thinnest thickness, conductor resistance, insulation wire core voltage test, the finished cable voltage test, insulation resistance, insulation aging before the tensile strength, insulation aging before the elongation at break, tensile strength after aging of insulation, insulation tensile strength after aging, insulation elongation after aging, insulation aging variation rate of elongation, weight loss test, insulation sheath aging before the tensile strength, elongation at break, sheath sheath aging before the tensile strength after aging, aging resistance. The rate of change of tensile strength, elongation after aging in sheath Time value, sheath after aging variation rate of elongation, sheath weight loss test, insulation thermal shock test, thermal shock test, sheath insulation thermal stability test, sheathing thermal stability test, bending test, non flammable, sign test content 29 items were tested.
Spot checks found that 83 batches of the product not in conformity with the provisions of the standard, relates to the average thickness of insulation, insulation thinnest thickness of sheath, sheath, the average thickness of the thinnest thickness, conductor resistance, bending test, weight loss test, insulation sheath weight loss test, insulation aging before the breaking elongation rate, insulation elongation after aging, sign content etc. project.
Quality Inspection Administration said, has instructed the relevant provincial quality and technical supervision departments to continue to strengthen the unqualified products and their production enterprises according to law, shall be ordered to unqualified products production enterprises to implement the requirements of the rectification.
