EN 681-11996 was produced as a result of international discussions in which the United Kingdom took an active part. EN 681-11996 has been approved by CEN member bodies under the weighted voting procedures introduced in 1988 to coincide with the introduction of “New Approach” Directives from the Commission of the European Community. To ensure that these products do not have any detrimental effects on the quality of water intended for human consumption, the materials of construction in contact with water will be tested in accordance with the standards being developed by CEN/TC 64 concerned with effects of materials on water quality. In the absence of these standards, the respective national standard, BS 6920 applies. This standard supersedes requirements for vulcanized rubber seals types W, D, H and S, used in water and drainage applications as given in BS 2494 and these types will be withdrawn by amendment. 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. 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 requirements for vulcanized rubber seals, i.e. by October 1997.

This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by October 1996, and conflicting standards shall be withdrawn at the latest by October 1996.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 inative Annex ZA, which is an integral part of this standard. This Part is based on ISO 4633 and ISO 9631, bringing these two sets of requirements for cold and hot water respectively under one specification. The major changes from ISO 4633 and ISO 9631 have been to incorporate requirements for effect on water quality and ozone resistance. The emphasis 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 standard. 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 specification 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 pipeline industry which employ cast polyurethane seals.
