• 65.060.35 Irrigation and drainage equipment

This part of ISO 9912 specifies general construction requirements and test methods for automatic flushing strainer-type filters and disc filters (hereinafter called “filters”) intended for operation in agricultural irrigation systems.

It does not cover the aspects of filtration ability, efficiency and capacity (like quality of filtered water or time of operation before filter becomes entirely clogged).

NOTE 1 The parameters of filtration ability, efficiency and capacity, their definitions and their test methods are to be included in a separate ISO International Standard or Technical Report. The test methods will be described in that document, using water as defined by the client, to characterize the filter properties during operation with this water, or with water defined by the tester or the client, for comparison between various filters under identical operating conditions.

NOTE 2 ISO 9912-2 covers strainer-type filters and disc filters in general (see Clause 5).
