1、BRITISH STANDARD BS EN 1825-1:2004 Grease separators Part 1: Principles of design, performance and testing, marking and quality control The European Standard EN 1825-1:2004 has the status of a British Standard ICS 13.060.99 BS EN 1825-1:2004 This British Standard was published under the authority of
2、 the Standards Policy and Strategy Committee on 11 February 2005 BSI 11 February 2005 ISBN 0 580 45443 6 National foreword This British Standard is the official English language version of EN 1825-1:2004. In line with the consistent United Kingdom position during the development of this Standard, th
3、e UK recorded opposition to the proposal at CEN Formal Vote Stage. The technical reasoning behind the response is that the test arrangements are based on the use of light liquids rather than grease. The testing therefore, does not take account of temperature effects or the resistance to blockage or
4、clogging that occurs to Grease Separators in the field. The UK participation in its preparation was entrusted by Technical Committee B/505, Waste water engineering, to Subcommittee B/505/8, Separators, which has the responsibility to: A list of organizations represented on this subcommittee can be o

This European Standard shall be given the status of a national standard, either by publication of an ide
27、ntical text or by endorsement, at the latest by March 2005, and conflicting national standards shall be withdrawn at the latest by March 2005. This is the first part of the two part standard for grease separators. Part 2 gives guidelines for selection, installation, operation and maintenance of grea
28、se separators. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For the relationship with EU Directive(s), see informative Annex ZA, which is an integral part of th
29、is document. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Ital
30、y, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom. EN 1825-1:2004 (E) 5 1 Scope This standard specifies definitions, nominal sizes, principles of design, performance requirements, marking, testing and qua
31、lity control for grease separators. This standard applies to separators for the separation of greases and oils of vegetable and animal origin from wastewater by means of gravity and without any external energy. This standard does not cover grease separators intended to treat domestic wastewater from
32、 kitchen areas of single family dwellings, where the separator has a nominal size less than 1. The standard is not applicable for the separation of light liquids, e.g. petrol, fuel and heating oil, and does not cover the treatment of wastewater exclusively containing stable emulsions of greases and
33、oils. The standard does not cover the use of biological means (bacteria and enzymes). 2 Normative references The following referenced documents are indispensable for the application of this document.
