IEC 63174:2021 applies to electrically operated toothbrushes used for electric cleaning of teeth. Rechargeable toothbrushes and primary battery operated toothbrushes, both for adults and children, are within the scope of this document. This document describes the test methods for measurement of the performance parameters as listed in Clause 4. The purpose of this document is only to specify the…

This document specifies a method to determine the amounts of dimethylformamide (DMF) in footwear and footwear components containing polyurethane (PU) coated material. NOTE 1   In the footwear industry, when PU is injected (reaction moulded), this process does not require the use of DMF. For PU coated material, the use of DMF is possible. NOTE 2   Several abbreviations can be used for…

This document specifies the test conditions for the determination of the tensile properties of unidirectional fibre-reinforced plastic composites, based upon the general principles given in ISO 527-1. NOTE      Isotropic and orthotropic reinforced materials are covered by ISO 527-4. The methods are used to investigate the tensile behaviour of the test specimens and for determining the tensile…

This document specifies a method for the determination of the pH-value defined by the electrolytes extractable by cold water from a sample of paper, board or pulp. This document is applicable to all types of paper, board and pulp. As the quantity of extractable ionic material approaches zero, as in the case of highly purified pulps, the precision of the method becomes poor because of the…

IEC 62037-6:2021 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 62037-6:2021 defines the test fixtures and procedures recommended for measuring levels of passive intermodulation…

IEC 62037-6:2021 defines the test fixtures and procedures recommended for measuring levels of passive intermodulation generated by antennas, typically used in wireless communication systems. The purpose is to define qualification and acceptance test methods for antennas for use in low intermodulation (low IM) applications. This second edition cancels and replaces the first edition published in…

This document specifies the test procedures and a method of presenting results concerning the parameters which define the main characteristics to be included in the supplier's literature of the electro-pneumatic continuous pressure control valves, conforming to ISO 10094-1. The purpose of this document is: —    to facilitate comparison by standardizing the test methods and the presentation…

This document provides guidance for implementing the theories of the ISO 11843 series in various practical situation. As defined in this series, the term minimum detectable value corresponds to the limit of detection or detection limit defined by the IUPAC. The focus of interest is placed on the practical applications of statistics to quantitative analyses.

IEC 60794-1-219:2021 applies to optical fibre cables for use with telecommunication equipment and devices employing similar techniques, as well as hybrid telecommunication cables having a combination of both optical fibres and electrical conductors. The object of this document is to define test procedures to be used in establishing uniform requirements for the material compatibility performance…
