Vitreous and porcelain enamels — Low-voltage test for detecting and locating defects — Part 2: Slurr...
This document specifies a low-voltage test method for detecting and locating defects (pores, cracks or pop-offs) that occur in enamel coatings of corrugated and/or undulated profiles and that extend down to the metal base.
The method is based on colour effects (optical method) and is applicable to the precise detection of defects and their exact position. It can be used for non-flat, more…
Nickel et alliages de nickel — Nickel raffiné — Échantillonnage
Le présent document spécifie les modes opératoires d'échantillonnage d'une quantité maximale de 25 tonnes (métriques) de nickel raffiné de mêmes composition, taille et forme, fabriquée dans des conditions similaires de production.
This document specifies a system of fits applicable to metallic plain bearings used in general engineering for mean relative bearing clearances, ψm, of 0,56 ? up to 3,15 ?. Other clearance ranges can be used depending upon the requirements in specific applications.
This system of fits is not applicable to half‑bearings and bushes which, due to their special characteristics, are not measured by…
