This document specifies requirements for rubber- or plastics-covered conveyor belting of textile construction for use in underground mines and disposed on flat or troughed idlers. It is not applicable to light conveyor belts as described in ISO 21183-1. This document does not include requirements for plastics covers. These are agreed upon by the manufacturer and purchaser, taking into account the…

Le présent document spécifie les exigences relatives aux courroies transporteuses à structure textile recouvertes de caoutchouc ou de plastique pour utilisation dans les mines souterraines et disposées sur rouleaux plats ou en auge. Il ne s'applique pas aux courroies transporteuses légères décrites dans l'ISO 21183-1. Le présent document n'inclut pas les exigences relatives aux…

This document specifies a mild oxidation method to determine the content of carbon impurities (carbon material content not in the form of CNT, including amorphous carbon and trace amountd of other types of structured carbon) less stable than multiwall carbon nanotubes (MWCNTs) by thermogravimetric analysis (TGA) under carbon dioxide atmosphere. This document is applicable to the characterization…

This document specifies an inductively coupled plasma-optical emission spectrometer (ICP-OES) method for the determination of the ammonium citrate, disodium-etheylenediamine tetraacetic acid (EDTA) soluble phosphorus and potassium content in fertilizer extract solutions. This document is applicable to all inorganic fertilizer products, whether compound or complex fertilizer products or blends…

This document describes a model [the predicted heat strain (PHS) model] for the analytical determination and interpretation of the thermal stress (in terms of water loss and rectal temperature) experienced by an average person in a hot environment and determines the maximum allowable exposure times within which the physiological strain is acceptable for 95 % of the exposed population (the maximum…

IEC 60068-2-14:2023 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 60068-2-14:2023 provides tests with specified ambient temperature changes to analyse their impacts on…

IEC 60455-2:2023 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 60455-2:2023 specifies methods of test to be used for testing resin based reactive compounds, their components…

Le présent document spécifie l’identification et le mesurage de l’activité d’un grand nombre de radionucléides émetteurs gamma, dans des sols, par spectrométrie gamma. Cette méthode non destructive applicable à des échantillons de grand volume (jusqu’à 3 l) permet de déterminer, par un seul mesurage, tous les émetteurs γ présents dont l’énergie des photons est comprise entre 5 keV et 3 MeV. La…

This document specifies the identification and the measurement of the activity in soils of a large number of gamma-emitting radionuclides using gamma spectrometry. This non-destructive method, applicable to large-volume samples (up to about 3 l), covers the determination in a single measurement of all the γ-emitters present for which the photon energy is between 5 keV and 3 MeV. Generic test…

IEC 60601-2-57:2023 applies to basic safety and essential performance of equipment incorporating one or more sources of optical radiation in the wavelength range 200 nm to 3 000 nm, with the exception of laser radiation, and intended to create photobiological effects in humans for therapeutic, diagnostic, monitoring, and cosmetic or aesthetic applications; hereafter referred to as light source…
