Nuclear fuel technology — Sintered (U,Pu)O2 pellets — Guidance for ceramographic preparation for mic...
ISO 22765:2016 describes the ceramographic procedure used to prepare sintered (U,Pu)O2 pellets for qualitative and quantitative examination of the pellet microstructure.
The examinations are performed before and after thermal treatment or chemical etching.
They allow
- observation of any cracks, intra- and intergranular pores or inclusions, and
- measurement of the grain size, porosity and…
Petroleum and liquid petroleum products — Measurement of level and temperature in storage tanks by a...
ISO 4266-3 gives guidance on the accuracy, installation, commissioning, calibration and verification of automatic level gauges (ALGs) both intrusive and non-intrusive, for measuring the level of petroleum and petroleum products having a vapour pressure less than 4 MPa, stored in pressurized storage tanks.
ISO 4266-3 gives guidance on the use of ALGs in custody transfer application.
ISO 4266-3 is…
Medical laboratories — Concepts and specifications for the design, development, implementation and u...
The proposed standard document specifies requirements for ensuring quality, safety and performance of laboratory-developed tests (LDT). It outlines the general principles and assessment criteria by which LDT shall be designed, developed, manufactured, validated and monitored for internal use by medical laboratories.
While the proposed standard follows a current best practice and state-of-the art…
Textiles — Détermination de l'activité virucide de produits textiles
Le présent document spécifie des méthodes d'essai permettant d'évaluer l'activité virucide des produits textiles contre des virus spécifiés. En raison des différences de sensibilité, les résultats obtenus avec un virus d'essai ne peuvent pas être transposés à d'autres virus.
Les produits textiles incluent les tissus, les tricots, les fibres, les fils, les tresses, etc.
Conception de l’environnement des bâtiments — Environnement intérieur — Principes généraux
L'ISO 16813:2006 établit les principes généraux de la conception de l'environnement des bâtiments, en prenant en compte l'aspect sanitaire de l'espace intérieur pour les occupants ainsi que la préservation de l'environnement pour les générations futures. La présente Norme internationale propose une approche où les parties prenantes à la conception des bâtiments concourent…
Plastics — Determination of the viscosity of polymers in dilute solution using capillary viscometers...
This document defines the general conditions for the determination of the reduced viscosity, intrinsic viscosity and K‑value of organic polymers in dilute solution. It defines the standard parameters that are applied to viscosity measurement.
This document is used to develop standards for measuring the viscosities in solution of individual types of polymer. It is also used to measure and report…
