This international standard is intended to provide a protocol for the interlab validation of methods for the characterization of sludge/biosolids physical properties considered that in most cases fresh sludge samples cannot be circulated to several laboratories in different countries for validation purposes as uncontrolled variations of their characteristics would occur.

This international standard specifies a chemical conditioning procedure for sludge/biosolids thus allowing results obtained in different places and laboratories, and on different times to be compared when selecting type and dosage of a conditioning product at laboratory scale.

This document specifies general requirements and guidance for metagenomics-dedicated sample preparation, generating and analyzing metagenomics sequence data obtained from massive parallel sequencing platforms. The specified metagenomics process includes the following stages: a) Sampling strategy and process, including type, storage, transportation, extraction, quality; b) Nucleic acid library…

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…

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…

This International Standard specifies the techniques for calibration and usage of pressurised, well-type ionisation chambers for the assay of radionuclides. Such instruments are used to determine the activity, expressed in becquerel (Bq), of photon and some medium to high-energy beta emitting radionuclides. This document provides the methods and tests for establishing and maintaining acceptable…

This document specifies requirements and test methods for powered polymerization activators in the 380 nm to 515 nm wavelength region intended for chairside use in polymerization of dental polymer-based materials. This document applies to quartz-tungsten-halogen lamps and light-emitting diode (LED) lamps. Powered polymerization activators could have internal power supply (rechargeable battery…

This document specifies a process for a medical laboratory to identify and manage the risks to patients, laboratory workers and service providers that are associated with medical laboratory examinations. The process includes identifying, estimating, evaluating, controlling and monitoring the risks. The requirements of this document are applicable to all aspects of the examinations and services of…

This standard would provide general requirements and guidance for the development and application of LAMP-based methods for the detection of microorganisms and associated genetic markers sampled along the food chain (e.g., ingredients, human food, animal food, and the production environment), and includes sample preparation, isothermal amplification, signal detection, data interpretation, and…

This document provides guidance and considerations for healthcare organizations to deliver diagnostic tests timely and accurately in a pandemic by leveraging innovative approaches to overcome the limitations of laboratory capacity as follows: – mitigating threats encountered in providing diagnostic services during a pandemic; – consideration for quality assurance of diagnostic service provision…
