Nanotechnologies — Multiwall carbon nanotubes — Determination of carbon impurity content by thermogr...
This document specifies a mild oxidation method to determine the content of carbon impurities (carbon material content not in the form of CNT, including amorphous carbon and trace amountd of other types of structured carbon) less stable than multiwall carbon nanotubes (MWCNTs) by thermogravimetric analysis (TGA) under carbon dioxide atmosphere.
This document is applicable to the characterization…
Fertilizers, soil conditioners and beneficial substances — Determination of ammonium citrate, disodi...
This document specifies an inductively coupled plasma-optical emission spectrometer (ICP-OES) method for the determination of the ammonium citrate, disodium-etheylenediamine tetraacetic acid (EDTA) soluble phosphorus and potassium content in fertilizer extract solutions.
This document is applicable to all inorganic fertilizer products, whether compound or complex fertilizer products or blends…
Ergonomics of the thermal environment — Analytical determination and interpretation of heat stress u...
This document describes a model [the predicted heat strain (PHS) model] for the analytical determination and interpretation of the thermal stress (in terms of water loss and rectal temperature) experienced by an average person in a hot environment and determines the maximum allowable exposure times within which the physiological strain is acceptable for 95 % of the exposed population (the maximum…
Mesurage de la radioactivité dans l'environnement — Sol — Partie 3: Méthode d'essai des ra...
Le présent document spécifie l’identification et le mesurage de l’activité d’un grand nombre de radionucléides émetteurs gamma, dans des sols, par spectrométrie gamma. Cette méthode non destructive applicable à des échantillons de grand volume (jusqu’à 3 l) permet de déterminer, par un seul mesurage, tous les émetteurs γ présents dont l’énergie des photons est comprise entre 5 keV et 3 MeV.
La…
Measurement of radioactivity in the environment — Soil — Part 3: Test method of gamma-emitting radio...
This document specifies the identification and the measurement of the activity in soils of a large number of gamma-emitting radionuclides using gamma spectrometry. This non-destructive method, applicable to large-volume samples (up to about 3 l), covers the determination in a single measurement of all the γ-emitters present for which the photon energy is between 5 keV and 3 MeV.
Generic test…
Small medical gas cylinders — Pin-index yoke-type valve connections
This document is applicable to pin-index yoke-type valve connections for medical gas cylinders, with a working pressure up to a maximum of 200 bar or test pressure up to a maximum of 300 bar, or both.
NOTE 1 This type of connection is primarily used for small cylinders (5 l or below).
NOTE 2 In this document the unit bar is used, due to its universal use in the field of technical…
Rubber — Determination of viscosity and stress relaxation using a rotorless sealed shear rheometer
This document describes a method for the determination of the viscosity and stress relaxation of raw or compounded rubber under specified conditions.
The viscosity determination consists of a constant strain, temperature and frequency test in which the elastic and the loss components of the complex shear modulus can be determined.
The determination of stress relaxation consists of a constant…
