This document describes two methods to measure in repeatable conditions the filtration efficiency of filter elements used in aviation and aerospace hydraulic fluid systems. It can be applied when evaluating the overall characteristics of a filter element according to ISO 14085-1, or separately. Since the filtration efficiency of a filter element can change during its service life as it is…

This document specifies the general characteristics of piston rings for reciprocating internal combustion engines for road vehicles and other applications (the individual dimensional criteria for these rings are given in the relevant International Standards). It also provides a system for ring coding, designation, and marking. It is applicable to all such rings of a nominal diameter from 30 mm up…

IEC TR 61282-14:2024 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 TR 61282-14:2024, which is a Technical Report, establishes a detailed analysis and calculations of the…

IEC TR 61282-14:2024 is available as IEC TR 61282-14:2024 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC TR 61282-14:2024, which is a Technical Report, establishes a detailed analysis and calculations of the uncertainties related to the measurement of the attenuation of both multimode and…

This document describes a method for determining the etch pit density, which is used to detect dislocations and processing-introduced defects that occur on single-crystal GaN substrates or single-crystal GaN films. It is applicable to the defects specified in ISO 5618-1 from among the defects exposed on the surface of the following types of GaN substrates or films: single-crystal GaN substrate;…

Le présent document décrit une méthode de détermination de la densité des piqûres qui est utilisée pour détecter les dislocations et les défauts induits par le process et qui sont rencontrés sur les substrats de GaN monocristallin ou les films de GaN monocristallin. Il est applicable aux défauts spécifiés dans l’ISO 5618-1 parmi les défauts émergents à la surface des types de substrats ou de…

Scope 1.1 These requirements cover Type I commercial kitchen exhaust hoods intended for placement over commercial cooking equipment. Exhaust hoods with and without exhaust dampers are covered by these requirements. 1.2 Exhaust hoods with and without exhaust fire actuated fire dampers are covered by these requirements. 1.3 Exhaust hoods are evaluated relative to minimum exhaust air flow…

Domaine d'application 1.1 Ces exigences couvrent les hottes d’évacuation de cuisine commerciale de type I éventuellement placées au-dessus d’équipements de cuisson commerciale. Les hottes d’évacuation avec et sans registres d’évacuation sont couvertes par ces exigences. 1.2 Les hottes d’évacuation avec et sans registres d’évacuation automatiques déclenchés en cas de feu sont couvertes…

IEC 62841-2-7:2024 deals with the safety of electric motor-operated hand-held spray guns for non-flammable materials. The rated voltage is not more than 250 V for single-phase a.c. or d.c. tools, and 480 V for three-phase a.c. tools. The rated input is not more than 3 700 W. The limits for the applicability of this standard for battery tools are given in K.1 and L.1. This standard deals with the…
