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…

Plastics — Determination of changes in colour and variations in properties after exposure to glass-f...
ISO 4582:2017 specifies methods to determine changes in colour and other appearance properties, and variations in mechanical or other properties, of plastics that have been exposed to glass-filtered solar radiation, to natural weathering or to simulated solar radiation from a laboratory source. The procedure used to analyse data depends on whether the test used to characterize the materials being…
Geotechnical investigation and testing — Laboratory testing of rock — Part 1: Determination of water...
This document will specify methods for the determination of the water content of rock.
This document is applicable to the laboratory determination of water content of rock samples
ISO 28079:2009 specifies a method for measuring the Palmqvist toughness of hardmetals and cermets at room temperature by an indentation method. ISO 28079:2009 applies to a measurement of toughness, called Palmqvist toughness, calculated from the total length of cracks emanating from the corners of a Vickers hardness indentation, and it is intended for use with metal-bonded carbides and…
Molecular biomarkers — Detection of DNA in cotton used for textile production — Part 1: Extraction o...
This document provides requirements and recommendations to laboratories that perform PCR analyses of
cottonseed, leaf, cotton fibre and cotton fibre-derived materials. The following are within the scope of this
document:a) identifying the materials to be assessed, based on the probability of obtaining good quality, fit for
purpose DNA from the materials in subsequent steps in the cotton cloth…
Flexible and rigid cellular polymeric materials — Accelerated ageing tests
This document specifies, for flexible and rigid cellular polymeric materials, laboratory procedures which are intended to imitate the effects of naturally occurring reactions such as oxidation or hydrolysis by humidity. The physical properties of interest are measured before and after the application of the specified treatments.
Test conditions are only given for open cellular latex, both open-…
