the filterability as defined is not dependent on the viscosity of the oil

This part of ISO 5167 is applicable only to cone meters in which the flow remains subsonic throughout the measuring section and where the fluid can be considered as single-phase

Multimode cables are typically tested at 1 300 nm

Cryogenic vessels. Pressure-relief accessories for cryogenic service - Reclosable pressure-relief valves Ingestion-build-54484 National Aeronautics Space Administration1 Scope This International Standard specifies the requirements for the design, manufacture and testing of pressure relief valves for cryogenic service, i. e. for operation with cryogenic fluids in addition to operation at temperatures from ambient to cryogenic. It is a requirement of this International Standard that the valves comply with ISO 4126 1; in the event of different requirements, this International Standard takes precedence. This
