End-face image analysis procedure for the calibration of optical fibre geometry test sets
Describes the calibration of test sets which perform end-face image analysis. This is also known as near-field or grey-scale analysis. The principles may also be applied to test sets of a different type.
This standard addresses the calibration of measurements made on single-mode fibres only. This type of test set may also be used to measure multimode fibres, but the evaluation of uncertainties…

Measurement of low-frequency magnetic and electric fields with regard to exposure of human beings - ...
Provides guidance for measuring the values of magnetic and electric fields with regard to exposure of human beings. The frequency range spans 15 Hz to 9 kHz. The standard covers magnetic fields with magnitudes from 100 nT to 100 mT, and electric fields from 1 V/m to 50 kV/m. Sources of fields include devices that operate at power frequencies and produce frequency harmonics. Other devices produce…
