The method specified in this International Standard measures the basic constituents in polyols that are soluble in glacial acetic acid and reactive with perchloric acid

at room temperature

BS EN 61857-31 is the 31st part of the IEC 61857 series that establishes an EIS evaluation for applications with a designed life of 5 000 h or less

This provides compatibility of all balanced components so that when they have been assembled the overall balance tolerance and/or vibration limit for the rotor assembly is met

Optics and photonics. Lasers and laser-related equipment. Test methods for laser beam power, energy and temporal characteristics has-digital BS ISO 20252:2012 sets a1 Scope This document specifies test methods for determining the power and energy of continuous wave and pulsed laser beams, as well as their temporal characteristics of pulse shape, pulse duration and pulse repetition rate. Test and evaluation methods are also given for the power stability of cw lasers, energy stability of pulsed lasers and pulse duration stability. The test methods given in this document are used for the testing and characterization
