13、mption, the materials of construction in contact with water will be tested in accordance with the method standards being developed by CEN/TC 64 concerned with effects of materials on water quality.

Other Parts of BS EN 681 will be published in the future to supersede requirements for type T and type G seals in BS 2494
15、. Attention is drawn to paragraph 2 of the European foreword. It was decided by CEN/TC 208 that there would be a one year transition period during which vulcanized rubber seals may be produced to either BS 2494 or BS EN 681-1. Following the changeover period, BS 2494 will be amended to delete requir

30、 October 1996. This standard has been prepared under a mandate issued to CEN by the European Commission and the European Free Trade Association and supports Essential Requirements of EU Directives. For the relationship with the EU Directives, see informative Annex ZA, which is an integral part of th

The major changes from ISO 4633 and ISO 9631 have been to incorporate requirements for effect on water quality and ozone resistance. The em
32、phasis in respect of low temperature testing has moved away from hardness measurement to compression set, which is more discriminating. A European Standard is to be prepared for material effects on water quality and when published it is intended that materials comply with the requirements of that st
33、andard. A European Standard is also to be prepared for microbiological deterioration requirements and when published it is intended that materials comply with the requirements of that standard. Part 2 has been prepared by CEN/TC 208 in response to requests from CEN/TC 155 for a material specificatio
34、n for thermoplastic elastomer seals for use in conjunction with non-pressure thermoplastic pipe systems. Part 3 has been prepared in response to those sections of the pipeline industry which employ cellular seals of vulcanized rubber. Part 4 has been prepared in response to those sections of the pip
35、eline industry which employ cast polyurethane seals.
