Abstract: The current paper states the contrast on standard system structure of plastic products between China, international standardization organization (ISO) and US, and also compares the plastic products safety supervision system of China and that of the other countries. It is found that in the field of daily plastic products, there are lots of product standards in China, but lack of systematicness. For the plastic products which have the potential to contact food or skin, there is lack of framework standards or relevant regulations to prevent risk of products safety. In the field of plastic pipes, fittings and valves, the standard system in China is largely consistent with that in ISO, however, it is suggested to accelerate the establishment of national standards on plastic pipes for trenchless renovation, due to the rapid development of this industry in China.
