Nuclear energy — Nuclear fuel technology — Methodologies for radioactivity characterization of very ...
This document describes methodologies for radioactivity characterization of very low-level waste (VLLW) generated from the operation or decommissioning of nuclear facilities. The purpose is to differentiate VLLW from low-level radioactive solid waste and waste below clearance levels. The aim is to effectively characterize and to demonstrate that it satisfies the criteria for VLLW.

Pigments and extenders — Dispersion procedure for sedimentation-based particle sizing of suspended p...
This document specifies sample preparation methods to determine the size distribution of separate particles of a single pigment or extender, which is dispersed in a liquid by application of a standardized dispersion procedure, using an ultrasonic device, shaker device or wet jet mill.
The sample preparation methods described are optimized for measurements carried out with a particle sizing…
Pigments et matières de charge — Mode opératoire de dispersion pour la détermination granulométrique...
Le présent document décrit des méthodes de préparation d’échantillon pour la détermination de la distribution granulométrique de particules séparées d’un pigment ou d’une matière de charge unique, qui est dispersé(e) dans un liquide en appliquant un mode opératoire de dispersion normalisé à l’aide d’un dispositif à ultrasons, d’un agitateur ou d’un broyeur à jets en voie humide.
Les méthodes de…
Géosynthétiques — Échantillonnage et préparation des éprouvettes
Le présent document établit les principes généraux de l'échantillonnage des géosynthétiques livrés sur sites de construction et de la préparation des éprouvettes à partir des échantillons.
Les principes d'échantillonnage sont applicables aux géosynthétiques livrés sous forme de rouleaux et de panneaux extensibles.

Heat-treatable steels, alloy steels and free-cutting steels — Part 7: Bright products of non-alloy a...
This document specifies the technical delivery requirements for bright steel products in the drawn, peeled/turned or additional ground condition and they are intended for mechanical purposes, for example for machine parts. The bright steel products are subdivided into the following steel types:
a) non-alloy general engineering steels;
b) non-alloy free-cutting steels;
c) non-…
Nuclear energy — Reference beta-particle radiation — Part 1: Methods of production
This document specifies the requirements for reference beta radiation fields produced by radioactive sources to be used for the calibration of personal and area dosemeters and dose-rate meters to be used for the determination of the quantities Hp(0,07), H'(0,07;Ω), Hp(3) and H'(3;Ω), and for the determination of their response as a function of beta particle energy and angle of incidence…
Fine bubble technology — Transportation and dispensing systems for agro- and aqua-cultural applicati...
This document specifies a test procedure, equipment and environment for evaluating the concentration loss of ultrafine bubbles (UFB) due to long-distance transfer of ultrafine bubble water in a plastic pipe. The test results are analysed and expressed in terms of a formula with the flow parameters, pipe length, flow velocity and number of circulations through the pipe. The formula is intended to…
Geosynthetics — Sampling and preparation of test specimens
This document establishes general principles for the sampling of geosynthetics delivered to construction sites, and for the preparation of test specimens from the samples.
The sampling principles are applicable to geosynthetics supplied in rolls or expandable panels.
NOTE ISO 186 can be used for products supplied in sheet form.
The specimen-preparation principles are applicable to all…
