Lasers and laser-related equipment — Test methods for laser-induced damage threshold — Part 1: Defin...
ISO 21254-1:2011 defines terms used in conjunction with, and the general principles of, test methods for determining the laser-induced damage threshold and for the assurance of optical laser components subjected to laser radiation.
ISO 1953:2015 specifies reference methods for the size analysis of coal by manual sieving (wet or dry), using test sieves of aperture sizes between 125 mm and 45 μm. A guide to sampling is given in Annex A.
This International Standard is applicable to all hard coals. It is not applicable to coke or other manufactured fuels.
In the case of pulverized coal which has been ground so that a high…

Soil quality — Sampling — Part 105: Packaging, transport, storage and preservation of samples
ISO 18400-105:2017 establishes general principles for packing, preservation, transport and delivery of samples of soil and related materials with an emphasis on requirements for when chemical analysis of the samples is required, but with the intention that the general procedures are to be adapted as appropriate when other forms of testing are required (e.g. biological testing, physical tests on…
Water quality — Determination of the toxicity of water samples on the embryo-larval development of t...
This document specifies a method for determining the effects of chemical and aqueous samples on the embryo-larval development of marine bivalves. It allows the determination of the concentration levels that result in an abnormality in embryo-larval development. This test is suitable for salinity ranges between 20 and 40 for mussels and between 25 and 35 for oysters. This method applies to

Water quality — Estimation of measurement uncertainty based on validation and quality control data
This International Standard specifies methods for the estimation of measurement uncertainty of chemical and
physicochemical methods in single laboratories based on validation data and analytical quality control results
obtained within the field of water analysis.
NOTE 1 The principles of the estimation of uncertainty specified in this International Standard are consistent with the
principles…
