Henan Provincial Market Supervision Bureau spot checks plastic pipes and fittings and other products

Recently, the Henan Provincial Market Supervision and Administration Bureau issued the "Announcement on 57 Batches of Unqualified Product Quality and 1 Enterprise's Rejection of Inspection (Production and Processing Links.

This time, a total of 117 companies were randomly checked for plastic pipe fittings, and 27 companies did not get sampl.

This spot check is based on GB/T13662-2018 "Polyethylene (PE) Piping System for Water Supply Part 2: Pipes", GB/T18742-2017 "Polypropylene Piping Systems for Cold and Hot Water Part 2: Pipes" , GB/T18743-2017 "Polypropylene piping system for cold and hot water - Part 3: Pipe fittings", GB/T19472-2004 "Polybutene (PB) piping system for cold and hot water - Part 2: Pipe material" , GB/T28792-2012 "Heat-resistant polyethylene (PE-RT) piping system for cold and hot water - Part 2: pipes", GB/T5831-2006 "Rigid polyvinyl chloride (PVC-U ) Pipe", GB/T10001-2006 "Rigid Polyvinyl Chloride (PVC-U) Pipe for Water Supply", CJ/T272-2008 "Impact Modified Polyvinyl Chloride (PVC-M) Pipe for Water Supply", GB /T13664-2006 "Rigid Polyvinyl Chloride (PVC-U) Pipes for Low-Pressure Water Conveyance and Irrigation", JG/T3050-1998 "Insulated Electrical Sleeves and Fittings for Construction" and "Product Quality of the Second Batch of Plastic Pipes and Fittings in 2018" Henan "Implementation Plan for Provincial Supervision and Spot Check" and "Implementation Plan for Quality Supervision and Spot Check of Plastic Pipe Fittings in the Second Batch of Production and Processing in Henan Province in 2019", the specifications and dimensions, elongation at break, longitudinal shrinkage rate, heat and cold of plastic pipe and pipe products are Hydrostatic test, oxidation induction time, simply supported beam impact test, appearance, density, Vicat softening temperature, tensile yield strength, drop weight impact test, ring stiffness, flat test, compressive performance, impact performance, bending performance, Items such as heat resistance, flame retardancy (self-extinguishing time, oxygen index), electrical properties-dielectric strength, and hygienic properties were test.

After inspection, 83 batches of products meet the standard requirements, and 7 batches of products do not meet the standard requirements, mainly involving oxidation induction time, hydrostatic strength (20℃ 100h), hydrostatic strength (80℃ 165h), hydrostatic test (95℃) 22h), hydrostatic test (95℃ 165h), density, tensile yield strength and other ite.

In response to the problems found in this special supervision and spot check, the Henan Provincial Market Supervision and Administration Bureau has instructed the market supervision and management departments of the provincial municipalities and the counties (cities) directly under the provincial government to deal with them seriously in accordance with relevant laws and regulatio.

The Henan Provincial Market Supervision and Administration Bureau specially reminds consumers to pay attention to product quality and safe.
