Pelton hydraulic turbines - Model acceptance tests
IEC 63461:2024 applies to laboratory model tests of any type of Pelton hydraulic turbine with unit power greater than 5 MW. It contains the rules governing test conduct and provides measures to be taken if any phase of the tests is disputed.
The main objectives of this document are:
- to define the terms and quantities used;
- to specify methods of testing and of measuring the quantities…
Protective clothing against heat and flame — Part 1: Test method for complete garments — Measurement...
This document specifies the overall requirements, equipment and calculation methods to provide results that can be used for evaluating the performance of complete garments or protective clothing ensembles exposed to short duration flame engulfment.
This test method establishes a rating system to characterize the thermal protection provided by single-layer and multi-layer garments made of flame…
Reference materials — Requirements and recommendations for use
This document describes good practice in using reference materials (RMs), and certified reference materials (CRMs) in particular, in measurement processes. These uses include:
— the assessment of precision and trueness of measurement methods;
— quality control;
— assigning values to materials;
— calibration;
— establishing conventional scales.…
Fans — Determination of airflow propelled through an open personnel door by a positive pressure vent...
This document establishes a uniform method of laboratory testing for the determination of airflow propelled through an open personnel door by a positive pressure ventilator.
NOTE The test described by this document is not entirely in accordance with ISO 5801, though it references several subclauses of ISO 5801 (such as the measurement of pressure and airflow).
This document does not…

Rubber, vulcanized — Determination of adhesion to wire cord
This document specifies two methods for determining the adhesion strength of vulcanized rubber to wire cord which is embedded in the rubber.
The two methods do not necessarily give the same results.
They are applicable primarily to test pieces prepared in the laboratory under standard conditions and used for the development and control of materials and processes utilized in the manufacture of…
Electronic displays - Part 2-7 : Measurements of optical characteristics - Tiled displays
IEC 62977-2-7:2024 specifies standard measuring conditions and measurement methods for determining the optical characteristics of tiled displays which consist of multiple display modules in order to form one screen. These methods apply to emissive and transmissive direct view flat displays that render real 2D images with all modules lying in the same plane. The methods are applicable in…
Rubber, vulcanized or thermoplastic — Determination of stress relaxation in compression — Part 1: Te...
This document specifies two procedures for determining the decrease in counterforce exerted by a test piece of vulcanized or thermoplastic rubber which has been compressed to a constant deformation and maintained thus at a predetermined test temperature.
The counterforce can be determined either by means of a continuous-measurement system or by a discontinuous-measurement one.
Two test methods…
