Matériaux métalliques — Essai de dureté Knoop — Partie 1: Méthode d'essai
Le présent document spécifie la méthode d’essai de dureté Knoop pour les matériaux métalliques, pour des forces d’essai comprises de 0,009 807 N à 19,613 N.
Le présent document spécifie l’essai de dureté Knoop pour la longueur de la grande diagonale ≥ 0,020 mm. L’utilisation de cette méthode pour déterminer la dureté Knoop d’empreintes plus petites ne fait pas partie du domaine d’application du…
Acoustics — Determination of acoustic properties in impedance tubes — Part 2: Two-microphone techniq...
This test method covers the use of an impedance tube, two microphone locations and a frequency analysis system for the determination of the sound absorption coefficient of sound absorbing materials for normal incidence sound incidence. It can also be applied for the determination of the acoustical surface impedance or surface admittance of sound absorbing materials. As an extension, it can also…
Acoustique — Détermination des propriétés acoustiques aux tubes d’impédance — Partie 2: Méthode à de...
La présente méthode d’essai traite de l’utilisation d’un tube d’impédance, de deux emplacements de microphones et d’un système d’analyse de la fréquence pour la détermination du coefficient d’absorption acoustique des matériaux acoustiques absorbants sous incidence acoustique normale. Elle peut aussi être utilisée pour déterminer l’impédance acoustique de surface ou l’admittance de surface des…
This document specifies the quality requirements, analytical methods, and packaging, labelling, marking, storage and transportation conditions for bee pollen.
This document is applicable to bee pollen collected at the entrance of beehives by Apis mellifera and other bees’ species of colonies, as well as dried, frozen and lyophilized bee pollen.
It does not apply to crushed powdery bee pollen and…
Metallic materials — Knoop hardness test — Part 1: Test method
This document specifies the Knoop hardness test method for metallic materials for test forces from 0,009 807 N to 19,613 N.
This document specifies Knoop hardness tests for length of the long diagonal ≥0,020 mm. Using this method to determine the Knoop hardness from smaller indentations is outside the scope of this document as results would suffer from large uncertainties due to the limitations…
Safety and control devices for gas burners and gas-burning appliances — Particular requirements — Pa...
This document specifies safety, construction, performance and testing requirements for multifunctional controls with integral overpressure protection safety function (OPSF) intended for use with portable gas appliances.
This document is applicable to:
— multifunctional controls which consist of a pressure-limiting device and at least one or more controls, including but not limited to a manual…
Information technology — Office equipment — Method for the determination of ink cartridge yield for ...
The purpose of this document is to provide a method to determine the ink cartridge yield of ink-containing cartridges (i.e. integrated ink cartridges and ink cartridges without integrated print heads) for colour photo printing with colour inkjet printers and multifunction devices that contain inkjet printer components. In the case where a cartridge set can be used in multiple printer models, only…
