Optical fibre cables - Part 1-2: Generic specification - Cross reference table for optical cable tes...
IEC 60794-1-2:2013 applies to optical fibre cables for use with telecommunication equipment and devices employing similar techniques, and to cables having a combination of both optical fibres and electrical conductors. The object of this standard is to provide the end user with a cross reference table between the second edition of IEC 60794-1-2:2003 and the five new separate parts into which is…

ISO/TS 15530-1:2013 provides an overview of the ISO 15530 series. It discusses the metrological characteristics of coordinate measuring machines (CMMs), the sources of task-specific uncertainty, and the relationship between the ISO 10360 and ISO 15530 series.
Wind turbines — Part 11: Acoustic noise measurement techniques
1 Scope
This part of IEC 61400 presents measurement procedures that enable noise emissions of a
wind turbine to be characterised. This involves using measurement methods appropriate to
noise emission assessment at locations close to the machine, in order to avoid errors due to
sound propagation, but far away enough to allow for the finite source size. The procedures
described are different…
