BS ISO 9912-1:2004 PDF

1   Scope This part of ISO 9912 defines terms used in relation to filters intended for agricultural micro-irrigation systems — in particular, pressurized systems — and provides a means of classifying those filters according to filtration method, structure, operating principle and function. It does not deal with classification according to the type of water intended to be filtered; nor does it apply to the classification of filters for potable or domestic water use.
