The manufacturers can ascertain the quality of their water and sewage pipe products by testing them according to product standards. The test results, together with 3rd party inspection services, can be used in acquiring type approvals or quality certificate such as Nordic Poly Mark.
During the product development phase the tests can be used to optimize the product design in such a way that the raw materials can be utilized up to their full technical and economic performance. Optimization serves also ecological objectives if the amount of waste material and waste production can be minimized.
