ISO 22412:2017 specifies the application of dynamic light scattering (DLS) to the measurement of average hydrodynamic particle size and the measurement of the size distribution of mainly submicrometre-sized particles, emulsions or fine bubbles dispersed in liquids. DLS is also referred to as "quasi-elastic light scattering (QELS)" and "photon correlation spectroscopy (PCS),"…

Protective clothing — Protection against flame — Limited flame spread materials, material assemblies...
ISO 14116:2015 specifies the performance requirements for the limited flame spread properties of all materials, all material assemblies, and protective clothing in order to reduce the possibility of the clothing burning when in occasional and brief contact with small flames and thereby constituting a hazard. Additional requirements for clothing are also specified, including design requirements,…
Protective clothing — Clothing to protect against heat and flame — Minimum performance requirements
ISO 11612:2015 specifies performance requirements for protective clothing made from flexible materials, which are designed to protect the wearer's body, except the hands, from heat and/or flame. For protection of the wearer's head and feet, the only items of protective clothing falling within the scope of ISO 11612:2015 are gaiters, hoods, and overboots. However, concerning hoods,…

Sludge and solid environmental matrices — Determination of dry residue or water content and calculat...
The method specified can be applied to all types of soil samples. Different procedures are specified for air-dried soil samples, e.g. samples pretreated according to ISO 11464, and for field-moist soil samples. Its principle is drying soil samples to constant mass at 105 °C and using the difference in mass of an amount of soil before and after the drying procedure to calculate the dry matter and…
Qualité de l'eau — Estimation de l'incertitude de mesure basée sur des données de validati...
La présente Norme internationale spécifie des méthodes pour l'estimation de l'incertitude de mesure des
méthodes chimiques et physicochimiques dans des laboratoires individuels, basée sur des données de
validation et sur les résultats du contrôle qualité analytique obtenus dans le domaine de l'analyse de l'eau.
NOTE 1 Les principes de l'estimation de l'incertitude de…
