Recently, the Henan Provincial Market Supervision and Administration Bureau announced the quality supervision and random inspection of the first batch of PVC plastic products for electrical fire comprehensive management in the production and processing links in 201 A total of 16 batches of soft PVC plastic products for wires and cables produced by 16 enterprises in 3 provincial cities including Zhengzhou, Luoyang and Xinxiang and 2 provinces (cities) directly managed by Gongyi and Huaxian were selected for this special spot che.
This special spot check is based on GB/T 8815-2008 "Soft PVC Plastics for Wires and Cables" and "Henan Province's 2019 First Batch of Electric Fire Comprehensive Management of Soft PVC Plastics for Wire and Cable Products Quality Provincial Special Supervision and Spot Checks" Implementation", the appearance, tensile strength, tensile strain at break, thermal deformation, thermal stability time at 200℃, volume resistivity at 20℃, volume resistivity at working temperature, The thermal aging properties (tensile strength after aging/maximum change rate of tensile strength, tensile strain at break/maximum change rate of tensile strain at break after aging, mass loss during thermal aging) and other items were test.
