GB/T 18690.2-2017 Agricultural irrigation equipment—Filters for microirrigation—Part 2:Strainer-type filters and disc filters

Scope

This part of GB/T 18690 specifies the general structural requirements and test methods for mesh filters and pleated filters (hereinafter referred to as filters) used in agricultural irrigation systems. This part does not address the filter's filtration performance, efficiency, and capacity (such as the quality of filtered water, the operating time before the filter is completely clogged, etc.), nor does it address the structural requirements and testing of filters with automatic flushing devices as specified in GB/T 18690.3. Note: The definitions and test methods for the filter's filtration performance, efficiency, and capacity parameters will be provided in other ISO technical reports. This technical report will specify the test methods for comparing various filters under the same operating conditions using water specified by the user, in order to characterize the filter's operating characteristics in the water specified by the user or the tester.
