Re-sintering test for UO2, (U,Gd)O2 and (U,Pu)O2 pellets
ISO 15646:2014 describes a procedure for measuring the densification of UO2, (U,Gd)O2, and (U,Pu)O2 pellets, achieved by heat treatment under defined conditions.
The densification of fuel in power operation is an important design feature. Essentially, it is dependent on structural parameters such as pore size, spatial pore distribution, grain size, and in the case of (U,Gd)O2 and (U,Pu)O2, oxide…
Test de refrittage pour pastilles UO2, (U,Gd)O2 et (U,Pu)O2
L'ISO 15646:2014 décrit un mode opératoire de mesurage de la densification de pastilles de UO2, (U,Gd)O2 et (U,Pu)O2 par traitement thermique dans des conditions définies.
La densification du combustible en réacteur est une caractéristique de conception essentielle. Elle dépend principalement de paramètres structuraux comme la taille des pores, la distribution des pores dans l'espace,…
Ships and marine technology — Marine environment protection — Oil booms — Part 1: Design requirement...
ISO 17325-1:2014 specifies the basic design requirements, general function, designations and marking of oil booms. It further specifies minimum information regarding design, dimensions and materials of oil booms to be provided by the manufacturer.
The intent of ISO 17325-1:2014 is to assist manufacturers and facilitate user selection of booms by technical criteria. It does not purport to address…
Implants for surgery — In vitro evaluation for apatite-forming ability of implant materials
ISO 23317:2014 specifies a method for detecting apatite formed on a surface of a material in simulated body fluid (SBF). It is applicable to implant surfaces intended to come into direct bone contact.

Plastics — Acquisition and presentation of comparable multipoint data — Part 3: Environmental influe...
ISO 11403-3:2014 specifies test procedures for the acquisition and presentation of multipoint data which demonstrate the behaviour of plastics under the following environments:
prolonged exposure to heat;
liquid chemicals;
environmental stress cracking under a constant tensile stress;
artificial weathering.
The tests are listed in order of increasing severity of the environment. By testing…
