1 Scope This part of ISO 9912 specifies general construction requirements and test methods for strainer filters and disc filters (hereinafter called filters) intended for operation in agricultural irrigation systems. This part of ISO 9912 does not cover the aspects of filtration ability, efficiency, and capacity (like quality of filtered water or time of operation before a filter becomes entirely clogged), nor does it deal with structural requirements or tests of automatic flushing mechanism filters that are covered by ISO 9912-3.
NOTE The parameters of filtration ability, efficiency, and capacity, their definitions, and their test methods are to be included in a separate ISO Technical Report. The test methods for comparing various filters under identical operating conditions will be described in that Technical Report, 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.
