GB/T20079-2006 mainly requires filters from technical requirements, test requirements, inspection requirements, marking, packaging, storage, etc.:
(1) The filter mainly proposes technical requirements from basic parameters, materials, performance, design and manufacture, among which:
1) The basic parameters are: filtration accuracy, rated flow, nominal pressure, dirt holding capacity, signaling pressure drop, bypass valve opening pressure drop, bypass valve sealing performance, bypass valve closing pressure drop, bypass valve pressure drop flow , filter initial pressure drop, precision filter pressure drop flow curve.
