Henan Provincial Quality Supervision Bureau spot checks 100 batches of plastic pipe fittings products
Learned from the official website of Henan Provincial Bureau of Quality and Technical Supervision, the bureau extracted Zhengzhou, Kaifeng, Luoyang, Pingdingshan, Hebi, Xinxiang, Jiaozuo, Puyang, Xuchang, Luohe, Sanmenxia, Nanyang, Shangqiu, Xinyang, Zhoukou, Zhumadian 16 provincial cities and Gongyi, Hua county, Dengzhou 3 provincial direct pipe county (city) production of 100 batches of plastic pipe products, There are 3 batches of products do not meet the requirements of the standard.
Basis for this spot inspection GB/T18742.2-2002 "Random copolymer polypropylene (PP-R) pipe for hot and cold water", GB/T18742.3-2002 "Random copolymer polypropylene (PP-R) pipe for hot and cold water", GB/T13663-2000 "Polyethylene (PE) pipe for water supply", GB/T5836.1-2006 "Hard polyvinyl chloride (PVC-U) pipe for Building drainage", GB/ T58362-2006 "Hard polyvinyl chloride (PVC-U) pipe for building drainage", GB/T10002.1-2006 "Hard polyvinyl chloride (PVC-U) pipe for water supply", CJ/T272-2008 "Impact modified polyvinyl chloride for water supply (PP-R)" Pvc-m pipe ", JG3050-1998 "Insulating electrical casing for construction", GB/T13664-2006 "Hard PVC (PVC-U) pipe for low-pressure water delivery irrigation" and "2017 the 2nd batch of plastic pipe fittings product quality Supervision and sampling inspection Implementation Plan of Henan Province", The identification, size, density, Vica softening temperature, longitudinal shrinkage rate, dichloromethane impregnation test, drop hammer impact test, tensile yield strength, elongation at break, oxidation induction time, cold and hot water hydrostatic test, simple beam impact test, compression performance, impact performance, bending performance, heat resistance, flame retardant performance, electrical performance, hygiene The main items such as energy were tested.
After sampling inspection, 97 batches of products meet the requirements of the standard, 3 batches of products do not meet the requirements of the standard. Henan Junhui Pipe Industry Co., LTD. 1 batch of construction insulation electrical bushing (specification model: φ 20415; Production date/batch number: 2016-04-09), the compressive performance and bending performance items were detected unqualified; 1 batch "Yu Huacheng "PVC-U water supply pipe of Xuchang Huacheng Plastic Industry Co., LTD. (Specification model: φ 110× 2.7 mm0.63 MPa; Production date/batch number: 2016-10-26), the detected density, hydraulic test (20¡æ1h), potassium permanganate consumption items were not qualified; 1 batch PVC-U drainage pipe of Henan Federation Plasticizing Technology Co., LTD. (Specification model: φ 110× 3.2 mm; Production date/batch number: 2017-04-16), was detected density, tensile yield strength, drop hammer impact test items unqualified.
