Industries du pétrole et du gaz, y compris les énergies à faible teneur en carbone — Coudes d'u...
Le présent document spécifie les conditions techniques de livraison des coudes fabriqués par le procédé de cintrage par induction et destinés aux systèmes de transport par conduites des industries du pétrole et du gaz naturel définis dans l'ISO 13623.
Le présent document est applicable aux coudes cintrés par induction, fabriqués à partir de tubes soudés et non soudés, en aciers non alliés ou…
Non-destructive testing — Acoustic emission testing (AT) — Leak detection by means of acoustic emiss...
This document specifies the general principles required for leak detection by acoustic emission testing (AT). It is addressed to the application of the methodology on structures and components, where a leak flow as a result of pressure differences appears and generates acoustic emission (AE).
It describes phenomena of the AE generation and influence of the nature of fluids, shape of the gap, wave…
Additive manufacturing of plastics — Environment, health, and safety — Test method for determination...
This document specifies test methods to determine particle emissions (including ultrafine particles) and specified volatile organic compounds (including aldehydes) from desktop MEX-TRB/P processes often used in non-industrial environments such as school, homes and office spaces in an emission test chamber under specified test conditions. However, these tests do not necessarily accurately predict…
Traditional Chinese medicine — Sterile three-edge needle for single use
This document specifies the configuration, dimensions, parameters, requirements and test methods of a sterile three-edge needle for single use. It also specifies requirements for packaging, labelling, transit and storage.
This document excludes requirements for the handle of a three-edge needle, which is structurally different from the body of a three-edge needle.
Essais non destructifs — Essais d’émission acoustique — Détection de fuites par émission acoustique
Le présent document définit les principes généraux exigés pour la détection de fuites au moyen d’essais d’émission acoustique. Il traite de l’application de la méthodologie sur les structures et les composants, lorsqu’un écoulement de fuite dû à des différences de pression se produit et génère une émission acoustique (EA).
Il décrit les phénomènes de génération d’EA et l’influence de la nature…
Fine bubble technology — Evaluation method for determining gas content in fine bubble dispersions in...
This document specifies the evaluation methods for hydrogen content in ultrafine bubble (UFB) dispersions.
The titration (oxidimetry) method can be used as a quick method to estimate the hydrogen content in hydrogen UFB dispersions. The lower limit of detection is 0,1 mg/l, and the range with acceptable accuracy is between 0,2 mg/l and 1,6 mg/l. The existence of oxidizing or reducing substances…
Internal combustion engines — Piston rings — Part 2: Coil-spring-loaded oil control rings of narrow ...
This document specifies the essential dimensional features of coil-spring loaded oil control rings made of cast iron, types DSF-C, SSF, GSF, DSF, SSF-L, DSF-NG and DSF-CNP. It is applicable to those piston rings in sizes 60 mm up to 160 mm, inclusive for reciprocating internal combustion engines for road vehicles and other applications.
