4、 The standards of plastic food packaging containers and medical and health products, such as GB 10010-2009 "medical flexible PVC pipes", GB 10457-2009 "plastic self-adhesive preservative film for food", GB / T 5009.100-2003 "Hygienic standard analysis method of expanded polystyrene molding products for food packaging", etc.

 

5、 The product standards of plastic mechanical parts are as follows: GB / T 24149.1-2009 "plastics polypropylene (PP) special materials for automobile part 1: bumper", GB 15558.2-2005 "buried polyethylene (PE) passenger road system for gas - Part 2: pipe fittings", GB / T 11063-2003 "polyamide sheet based flat belt", etc.

 

6、 The product standards of plastic electrical insulation are as follows: GB / T 11016.2-2009 plastic insulated and rubber insulated flexible telephone cords Part 2: PVC insulated telephone cords, GB / T 13542.4-2009 film for electrical insulation Part 4: polyester film, GB / Z 18890.3-2002 XLPE insulated power cable and its accessories for rated voltage of 220kV (UM = 252kV) Part 3: accessories for XLPE insulated power cables with rated voltage of 220kV (UM = 252kV).

 

7、 The product standards of flame retardant plastics are as follows: GB / T 24150-2009 plastic flame retardant and impact resistant polystyrene, GB / T 24151-2009 plastic glass fiber reinforced flame retardant polybutylene terephthalate special material, GB / T 19666-2005 general rules for flame retardant and fire resistant wires and cables, etc.

 

Eight, fill and enhance plastic product standards such as GB/T 26700-2011 "rigid polyurethane foam for door filling", GB/T 21492-2008 "glass fiber reinforced plastic pipe jacking", GB/T 24721.4-2009 "glass fiber reinforced plastic products for highway fourth part: unpressurized communication manhole cover" and so on.

 

9、 Product standards for special purpose plastics, such as GB / T 16167-2009 "lifeboat shell glass fiber reinforced plastic laminates technical conditions", GB 18191-2008 "packaging containers, plastic drums for packaging dangerous goods", etc.

2、 Testing method of plastics

 

Understanding the response of materials to load is the basis of understanding the properties of materials. By testing the deformation degree (strain) of the material under a certain stress, the designer can predict the application of the material in its working environment by using DSC, TG, IR, MS, LC, GC, XRD, SEM, etc, The specific equipment and price depends on the composition of your plastic, separation and so on.

 

3、 Plastic testing organization

 

Shenzhen Guowei testing is an authoritative organization specializing in aging and anti-aging research of polymer materials, performance testing and the revision of aging test methods. The testing center has advanced test instruments, which can carry out aging test, plastic test and performance test of various synthetic materials and their products according to international standards (ISO), national standards (GB), ASTM, DIN and JIS standards; it can carry out analysis and Research on storage life prediction and thermal index determination of synthetic materials. It is a third-party testing institution with fair status, which has passed CNAs and CMA. It can be used to test the performance of various polymer materials (plastics, rubber, coatings, adhesives) and their products, and to identify and grade the risk of chemicals.
