3、 1825-1:2004. 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
4、grease. The testing therefore, does not take account of temperature effects or the resistance to blockage or 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, S

29、 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of an identical text or by endorsement, at the latest by March 2005, and conflicting national standards shall be withdrawn at the latest by March 2005. This is the
30、 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 mandate given to CEN by the European Commission and the European Free Trade Association, and suppor
31、ts 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.

This standa
34、rd 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 kitchen areas of single family dwellings, wher
35、e 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 oils. The standard does not cover the use of bi
36、ological means (bacteria and enzymes). 2 Normative references The following referenced documents are indispensable for the application of this document.
