IEC 61280-4-2:2024 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 62180-4-2:2024 is applicable to the measurements of attenuation and optical return loss of an installed optical…

This document specifies a method for the measurement of effective focal spot dimensions above 0,1 mm of X-ray systems up to and including 1 000 kV X-ray voltage by means of the pinhole camera method with digital evaluation. The tube voltage applied for this measurement is restricted to 200 kV for visual film evaluation and can be selected higher than 200 kV if digital detectors are used. The…

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…

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…

This document provides guidance for the definition, implementation, evaluation, and improvement of the measurements necessary to effectively manage innovation activities in an organization. It establishes the fundamentals of innovation operation measurements and guides their application towards four areas: —     measurements for establishing and launching innovation initiatives; —    …

This document specifies a method for the determination of the static vulcanized adhesion strength of rubber compounds to rigid materials. The test piece is composed of two conical ends of the rigid material, joined by a cylinder of rubber. The adhesion is obtained by a bonding system which can include not only the rigid material and the rubber compound, but other elements such as thin alloy…

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 60793-1-41:2024 describes three methods for determining and measuring the modal bandwidth of multimode optical…

IEC 60793-1-45:2024 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 60793-1-45:2024 establishes uniform requirements for measuring the mode field diameter (MFD) of single-mode…

This document describes the methods that are available to perform a spectral analysis of a pavement surface profile. It specifies a method for performing spatial frequency analysis (or texture wavelength analysis) of two-dimensional surface profiles that describe the pavement texture amplitude as a function of the distance along a straight or curved trajectory over the pavement. It also details…

IEC 61643-332:2024 describes the theory of operation, principles for the selection and application of MOVs to be connected to power lines or telecommunication or signalling circuits, up to 1 000 V AC or 1 500 V DC. These SPCs are designed to protect apparatus or personnel, or both, from high transient voltages. This document applies to MOVs having two electrodes and voltage dependents elements…
