EN 681-1:1996 was produced as a result of international discussions in which the 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 method 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rubber seals types W, D, H and S, used in water and drainage applications as given in BS 2494 and these types will be withdrawn by amendment.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 BSEN 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 BSEN 681-1. Following the changeover period, BS 2494 will be amended to delete requirements for vulcanized rubber seals, i.e. by October 1997.

EN 681-1:1996Foreword This European Standard has been prepared by Technical Committee CEN/TC 208, Elastomeric seals for joints in pipework and pipelines, the Secretariat of which is held by BSI. withdrawn at the latest by October 1996.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 informative Annex ZA, which is an integral part of this standard. This Part is based on ISO4633 and ISO9631, bringing these two sets of requirements (for cold and hot water respectively) under one specification. The major changes from ISO4633 and ISO9631 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. According to the CEN/CENELEC Internal Regulations, the national standards organization of the following countries are bound to implement this European Standard: Austria, Belgium, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the ——————————————————————————————————————————————— United Kingdom.--`,,,,``,`,,,,`,,,`,,`,`,``,,-`-`,,`,,`,`,,`---Foreword to amendment A1 This amendment EN681-1:1996/A1:1998 to the EN681-1:1996 has been prepared by Technical Committee CEN/TC208, Elastomeric seals for joints in pipework and pipelines, the Secretariat of which is held by BSI. This amendment to the European Standard EN681-1:1996 shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by December1998, and conflicting national standards shall be withdrawn at the latest by December1998.

General requirements for finished joint seals are also given; any additional requirements called for by the particular application are specified in the relevant product standards taking into account that the performance of pipe joints is a function of the seal material properties, seal geometry and pipe joint design. This standard should be used where appropriate with product standards which specify performance requirements for joints. This standard is applicable to joint seals for all pipeline materials, including iron, steel, clay, fibre cement, concrete, reinforced concrete, plastics and glass-reinforced plastics. It is applicable to elastomeric components of composite or non-composite seals. In the case of composite seals for materials of hardness ranges from 76IRHD to 95IRHD the requirements for elongation at break, compression set and stress relaxation apply only when the material is participating in the sealing function, or the long term stability of the seal. Joint seals made with an enclosed void as part of their design are included in the scope of this European Standard.2 Normative references ——————————————————————————————————————————————— This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter.
