Measurement of radioactivity — Gamma emitting radionuclides — Rapid screening method using scintilla...
ISO 19581 specifies a screening test method to quantify rapidly the activity concentration of gamma-emitting radionuclides, such as 131I, 132Te, 134Cs and 137Cs, in solid or liquid test samples using gamma-ray spectrometry with lower resolution scintillation detectors as compared with the HPGe detectors (see IEC 61563).
This test method can be used for the measurement of any potentially…

Fans — Laboratory methods of testing air circulating fans
This standard shall be used as the basis for testing electrically powered air circulating fan heads and ceiling fans when air is used as the test gas. The scope is limited to air circulating fans with an input power greater than or equal to 125 W—except for ceiling fans that are larger than 1800 mm, which do not have a lower input power limit. The diameter of the fan being tested shall be limited…
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.…
In vitro diagnostic medical devices — Multiplex molecular testing for nucleic acids — Part 3: Interp...
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…
Measurement of radioactivity — Gamma ray and beta emitting radionuclides — Test method to assess the...
This document applies to the testing of surfaces that may become contaminated by radioactive materials.
The ease of decontamination is a property of a surface and an important criterion for selecting surface materials used in the nuclear industry, interim storage or disposal facilities from which contamination can be removed easily and rapidly without damaging the surface. The test described in…
