IEC 62522:2014 provides a stable and reproducible procedure to calibrate the wavelength and power output of a tuneable laser against reference instrumentation such as optical power meters and optical wavelength meters (including optical frequency meters) that have been previously traceably calibrated. Keywords: calibrate the wavelength and power output of a tuneable laser
Low-voltage switchgear and controlgear enclosed equipment - Part 1: Enclosed switch-disconnectors ou...
IEC 62626-1:2014 applies to enclosed switches-disconnectors with rated voltages up to 1 000 V a.c. for repair and maintenance work or cleaning work in load circuits. Devices within the scope of this standard are derived from switch-disconnectors according to IEC 60947-3. Enclosed switch-disconnectors in this standard are suitable for isolation according to IEC 60947 series and are not supposed to…
Specification for radio disturbance and immunity measuring apparatusand methods - Part 4-2: Uncertai...
CISPR 16-4-2:2011+A1:2014 is a basic EMC publication. It specifies the method of applying Measurement Instrumentation Uncertainty (MIU) when determining compliance with CISPR disturbance limits. The material is also relevant to any EMC test when interpretation of the results and conclusions reached will be impacted by the uncertainty of the measurement instrumentation used during testing. This…
Specifications for particular types of winding wires - Part 52: Aromatic polyamide (aramid) tape wra...
IEC 60317-52:2014 specifies requirements for tape wrapped round copper winding wire of temperature index 220. The insulation consists of one or more wrappings of aromatic polyamide (aramid) tape of various thicknesses. The range of nominal conductor diameters covered by this standard is:
- 1,600 mm up to and including 5,000 mm;
- the nominal conductor diameters are given in Table 1. This second…
