“essential” or “emergency” in nature and is therefore part of most EHR initiatives world-wide as evidenced in PD ISO/TR 12773-2

and the final machining aspect

Method L is applicable to situations where the material is exposed to high humidity conditions but without wetting from liquid water (low moisture) and method H is applicable to situations where the material is exposed to direct wetting (high moisture) for prolonged periods

Fibre-optic communication subsystem test procedures - Installed cabling plant. Attenuation measurement of MPO terminated fibre optic cabling plant using test equipment with MPO interfaces Ingestion-build-78747 BS EN 60669-2-5 is a1 Scope This part of IEC 61280 is applicable to the measurement of attenuation and determination of polarity and length of installed multimode and single mode optical fibre cabling plant, terminated with MPO connectors, using test equipment having an MPO interface. This cabling plant can include multimode or single mode optical fibres, connectors, adapters, splices, and other passive devices. The cabling can be installed in a variety of environments
