Plastic product inspection of the implementation of standards can be broadly divided into the following categories:
One, plastic raw materials such as product standards GB/T 5761-2006 "suspension method of general-purpose polyvinyl chloride resin", GB/T 12670-2008 "polypropylene (PP) resin", GB/T 12672-2009 "acrylonitrile-butadiene-styrene ( ABS) Resin" and so on.
Second, the plastic through the product standards such as GB/T 20207.1-2006 "acrylonitrile-butadiene-styrene (ABS) pressure piping system Part 1: Pipe", GB/T 10003-2008 "general purpose biaxially oriented polypropylene (BOPP) film", GB/T 3830-2008 "soft polyvinyl chloride calendered film and sheet" and so on. etc.
Three, plastic daily-use devices such as product standards GB 24429-2009 "sports helmets Bicycle, skateboarding, roller skating helmets safety requirements and test methods", GB/T 24984-2010 "daily-use plastic bags", GB/T 11793-2008 "unplasticized polyvinyl chloride (PVC-U) plastic windows and doors Mechanical Properties and Weathering Test Method". Methods".
