Plastics — Determination of dynamic mechanical properties — Part 4: Tensile vibration — Non-resonanc...
This document describes a forced, non-resonance method for determining the components of the tensile complex modulus E* of polymers at frequencies typically in the range 0,01 Hz to 100 Hz.
NOTE Higher frequency measurements can be made, but significant errors in the dynamic properties measured are likely to result (see 10.2.2 and 10.2.3).
The method is suitable for measuring dynamic storage…

Le présent document fournit les spécifications de base et les exigences d'essai des conteneurs-citernes ISO de la série 1 adaptés au transport des gaz, des liquides et des produits solides (en vrac) qui peuvent être chargés ou déchargés comme des liquides, avec déchargement par gravité ou sous pression, convenant aux échanges internationaux et au transport par route, par rail et par mer et…
Adhesives — Determination of the bond strength of engineering-plastic joints
This document describes a test method for measuring the shear and/or tensile strength of an adhesively bonded plastic/plastic specimen of a specific design. This method allows the determination of a combined shear and tensile behaviour of the bond. These shear and tensile values are useful for design purposes.
Jewellery and precious metals — Fineness of precious metal alloys
This document specifies a range of fineness of precious metal alloys (excluding solders) recommended for use in the field of jewellery.
NOTE There is a possibility that national legal requirements for the designation, marking, and stamping of finished articles exist in the respective countries.
Joaillerie, bijouterie et métaux précieux — Titre des alliages de métaux précieux
Le présent document spécifie les titres des alliages de métaux précieux (à l'exception des soudures) d'usage recommandé en joaillerie.
