| Название (англ.): | Plastics pipes for the transport of water intended for human consumption; extractability of constituents; test method |
| Описание (англ.): | Applies to all plastic pipes and relates to all constituents which are extractable by drinking water from a finished pipe. The pH and the temperature of the test water (simulant) and the exposure times have been chosen to cover extreme conditions. The principleconsists in prewashing a tubular test pipe for a specified time and filling the pipe with acidified or alkalified distilled water (simulated drinking water) at a temperature specified in the relevant product standard. Determination of the quantity of the extracted constituent after a fixed time. Expression of the results in milligram of a constituent per litre test water. |
