It is the UK implementation of EN 1825-1:2004, incorporating corrigendum M
6、ay 2006.In line with the consistent United Kingdom position during the development of this Standard, the 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.

25、nt (EN 1825-1:2004) has been prepared by Technical Committee CEN/TC 165 “Waste water engineering”, the secretariat of which is held by DIN. 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 March 20
26、05, and conflicting national standards shall be withdrawn at the latest by March 2005.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 grease separators. This document has been prepared under a m
27、andate 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 this document. According to the CEN/CENELEC Internal Regul
28、ations, 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, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, No

EN 1825-1:2004 (E) 5 1 Scope This standard specifies definitions, nominal sizes, principles of design, performance requirements, marking, testing and quality control for grease separators. This standard applie
30、s 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 kitchen areas of single family dwellings, where the sep
31、arator 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 oils. The standard does not cover the use of biological
32、means (bacteria and enzymes). 2 Normative references The following referenced documents are indispensable for the application of this document.
