Measurement of radioactivity in the environment — Bioindicators — Part 1: General guide for the samp...
This document describes the general principles pertaining to the sampling strategy, to the collection and conditioning of samples, to their transport to the laboratory and to the pre-treatment operations to be carried out prior to analysis.
Inlet air cleaning equipment for internal combustion engines and compressors — Performance testing
This document establishes and specifies uniform test procedures, conditions, equipment and a performance report to permit the direct laboratory performance comparison of air cleaners.
The basic performance characteristics of greatest interest are air flow restriction or differential pressure, dust collection efficiency, dust capacity and oil carry-over on oil bath air cleaners. This test code…
Railway infrastructure — Rail welding — Part 2: Aluminothermic welding
This document corresponds to the subsequent part of ISO 23300-1 "General requirements and test methods for rail welding" and specifies the requirements on rail aluminothermic welding, including the requirements for approval of an aluminothermic welding process, laboratory tests, contractor/welder, as well as the acceptance criteria of aluminothermic welds in track. In this document, 43…
Solar energy — Calibration of a pyranometer using a pyrheliometer
Its use is mandatory for the calibration of secondary standard pyranometers according to ISO 9060, and is recommended for the calibration of pyranometers which are used as reference instruments in comparisons. Is intended for use by test institutions or test laboratories equipped with well-maintained pyrheliometers and is applicable to all pyranometers. The object is to promote the uniform…
Paints and varnishes — Determination of resistance to humidity — Part 2: Condensation (in-cabinet ex...
ISO 6270-2:2017 specifies the general conditions and procedures which need to be observed when testing coated test specimens in constant condensation-water atmospheres or in alternating condensation-water atmospheres, in order to ensure that the results of tests carried out in different laboratories are reproducible.
NOTE The shape and preparation of the test specimens, the duration of the test…
ISO Guide 80 outlines the essential characteristics of reference materials for quality control (QC) purposes, and describes the processes by which they can be prepared by competent staff within the facility in which they will be used (i.e. where instability due to transportation conditions is avoided). The content of this Guide also applies to inherently stable materials, which can be transported…
Molecular in vitro diagnostic examinations — Specifications for pre-examination processes for urine ...
This document specifies requirements and provides recommendations for the pre-examination phase of cell free DNA (cfDNA) from body fluid specimens other than blood, including but not limited to the collection, handling, storage, transport, processing and documentation of human body fluids, such as urine, cerebrospinal fluid (CSF), pleural effusions and saliva, intended for cfDNA examination.…

This document gives general requirements for interpretation and reports of multiplex molecular tests using IVD medical devices and laboratory developed tests (LDTs), including qualitative/quantitative detection of nucleic acid targets.
This document is applicable to all the methods that are used for IVD medical devices and LDTs that measure two or more nucleic acid targets of interest. This…
Validation method for fire gas analysis — Part 3: Considerations related to interlaboratory trials
This document describes tools and gives guidance concerning interlaboratory trials related to fire effluent analyses. It explains the relative contributions from the physical fire model and analytical techniques to evaluate trueness and fidelity. It also explains the difficulties involved with the interpretation of round-robin data and with the evaluation of trueness in fire effluent analyses.…
