NOTE This International Standard only specifies tests for ambient and elevated temperature applications

— identification of additional needs for additional EFC related information exchange among the related entities

The methodology used in this standard is similar to that specified in IEC 60891 in which a linear (straight-line) function is fitted to a set of data points using a least-squares fit calculation routine

Safety of laser products - Safety of optical fibre communication systems (OFCS) Ingestion-build-79769 NOTE This International Standard only1 Scope and object This Part 2 of IEC 60825 provides requirements and specific guidance for the safe operation and maintenance of optical fibre communication systems (OFCS). In these systems optical power may be accessible outside the confinements of transmitting equipment or at great distance from the optical source. This Part 2 requires the assessment of hazard levels at accessible locations as a replacement for classification according to IEC
