The requirements apply if fixed and movable guards are used

Aerospace series. Hydraulic filter elements. Test methods - Conditioning Ingestion-build-133579 The following significant technical changes1 Scope This part of ISO 14085 specifies a procedure to thermally condition a hydraulic filter element to presumed aerospace hydraulic system stresses, a test procedure to complete cold soaks, hot soaks, and temperature variation in a combined manner, and a test procedure to simulate cold starts. This part of ISO 14085 is not intended to qualify a filter element under replicate conditions of service; this can only be done by a specific test protocol
