Optical fibres - Part 1-40: Attenuation measurement methods
IEC 60793-1-40:2019 establishes uniform requirements for measuring the attenuation of optical fibre, thereby assisting in the inspection of fibres and cables for commercial purposes. Four methods are described for measuring attenuation, one being that for modelling spectral attenuation:
– method A: cut-back;
– method B: insertion loss;
– method C: backscattering;
– method D: modelling…
Fibres optiques - Partie 1-40: Méthodes de mesurage de l'affaiblissement
IEC 60793-1-40:2019 établit des exigences uniformes pour mesurer l'affaiblissement d'une fibre optique, contribuant ainsi au contrôle des fibres et des câbles dans les relations commerciales. Quatre méthodes sont décrites pour mesurer l'affaiblissement, parmi lesquelles une méthode pour modéliser l'affaiblissement spectral:
– méthode A: fibre coupée;
– méthode B: pertes d…
Heat recovery ventilators and energy recovery ventilators — Method of test for performance — Part 2:...
This document provides guidance for practical applications of those principles in the measurement of the performance of ventilators falling under the scope of ISO 16494:2014. The references listed in the Bibliography give detailed information on the principles and theory of uncertainty as applied to measurements.
Plain bearings with liquid lubrication — Lubricant supply arrangements and monitoring
This document provides requirements and guidance on lubricant supply arrangements and monitoring for liquid-lubricated bearings (plain bearing assemblies) such as those specified in ISO 11687 (all parts).
This document is intended to assist the design of oil-based lubrication systems for hydrodynamic plain bearings mainly to be used in large-scale rotating machinery for power generation, industry…
Rubber, raw — Determination of volatile-matter content — Part 2: Thermogravimetric methods using an ...
1.1 This document specifies two thermogravimetric methods for the determination of moisture and other volatile-matter content in raw rubbers by using an automatic analyser with an infrared drying unit.
1.2 These methods are applicable to the determination of volatile-matter content in synthetic rubbers (SBR, NBR, BR, IR, CR, IIR, halogenated IIR and EPDM) listed in ISO 1629 and to various…
Belt drives — Pulleys — Limiting values for adjustment of centres
This document specifies the limiting values for the adjustment of centres of two transmission pulleys.
It is applicable to:
— crowned pulleys for flat belts;
— grooved pulleys for V-belts, either single, multiple or joined;
— grooved pulleys for V-ribbed belts;
— toothed pulleys for synchronous belts.
Test conditions for box type vertical drilling machines — Testing of the accuracy
This document specifies, with reference to ISO 230-1, geometrical tests on general purpose and normal accuracy box type vertical drilling machines. It also specifies the applicable tolerances corresponding to the above‐mentioned tests.
This document deals only with the verification of accuracy of the machine.
It does not apply to the testing of the machine operation (vibrations, abnormal noises…
