Recently, it was learned from the official website of Guangzhou Quality and Technical Supervision Bureau that in the fourth quarter of 2015, the bureau conducted supervision and spot checks on the quality of PVC insulated cable and wire products in the production field in Guangzhou, and a total of 95 batches of products produced by 57 enterprises were randomly inspected, all of which met the standard requirements
after inspection.
This spot check is based on the national standard GB/T 5023.
1-2008 "PVC insulated cables with rated voltage 450/750V and below - Part 1: General requirements", GB/T 5023.
2-2008 "PVC insulated cables with rated voltage 450/750V and below - Part 2: Test methods", GB/T 5023.
3-2008 "PVC insulated cables with rated voltage 450/750V and below" Part 3: Unsheathed cables for fixed wiring", GB/T 5023.
5-2008 "PVC insulated cables with rated voltage 450/750V and below - Part 5: Flexible cable (flexible wire)", GB/T 18380.
33-2008 "Combustion test of cables and optical cables under flame conditions Part 33: Vertical spread test of flame of vertically installed bundled wires and cables Type A", JB/T 8734.
1-2012 "Rated voltage 450/ 750V and below PVC insulated cables, wires and flexible wires Part 1: General provisions" and other standards
.
This sampling inspection is mainly for the conductor resistance of PVC insulated cable products, finished cable voltage test, insulated core voltage test, insulation resistance, average thickness of insulation, thickness of thinnest insulation, average thickness of sheath, thickness of sheath thinnest, tensile strength before insulation aging, elongation at break before insulation aging, tensile strength after insulation aging, elongation at break after insulation aging, tensile strength change rate after insulation aging, elongation at break after insulation aging, elongation at break change rate after insulation aging, loss on insulation weight test, tensile strength before sheath aging, Elongation at break before sheath aging, tensile strength after sheath aging, elongation at break after sheath aging, change rate of tensile strength after sheath aging, elongation at break change rate after sheath aging, sheath weight loss test, insulation thermal shock test, sheath thermal shock test, insulation thermal stability test, sheath thermal stability test, flexure test, non-retardant test and other items are tested
