This document describes a test method for the determination of radon-222 (222Rn) activity concentration in non-saline waters by extraction and liquid scintillation counting. The 222Rn activity concentrations, which can be measured by this test method utilizing currently available instruments, are above 0,5 Bq·l−1 which is the typical detection limit for a 10 ml test sample and a measuring time of…

This document specifies a method for determining the total content (solvent extractible) of the following bisphenols in leather: —     bisphenol A; —     bisphenol B; —     bisphenol F; —     bisphenol S. This method requires the use of liquid chromatography (LC) with either a single quadrupole mass spectrometer (MS), a triple quadrupole mass spectrometer (MS/MS), an ultraviolet (UV) detector, a…

IEC 61010-2-034:2023 specifies safety requirements to equipment for measuring insulation resistance and to equipment for testing electric strength which have an output voltage exceeding 50 V a.c. or 120 V d.c. This document also applies to combined measuring equipment which has an insulation resistance measurement function or an electric strength test measurement function. This document has the…

This document provides guidelines for the laboratory refining of various pulps intended for paper production including: —    Harmonization of terms and parameters for the simulation of industrial refining processes by laboratory refiners; —    Treatment of pulp samples in a (semi) continuous operation in contrast to the batch operation of laboratory beating equipment such as the PFI mill; —   …

This document specifies requirements and recommendations for the design and execution of an interlaboratory comparison for validation of new standardized analytical methods in the field of water analysis, e.g. the number of participating laboratories and time schedules. This document is based on ISO 5725-1 and ISO 5725-2. NOTE            The scope of other standards in the field of…

These international guidelines are based on the assumption that monitoring of environmental components (atmosphere, water, soil and biota) as well as food quality is performed to ensure the protection of human health[5][7][8][9][10][11][12]. The guidelines constitute a basis for the setting of national regulations, standards, and inter alia, for monitoring air, water and food in support of public…

This document specifies light emitting diodes (LED) for light source and radiometers used in the performance evaluation of semiconducting photocatalytic materials under indoor LED lighting environments in a laboratory. Light sources for indoor lighting environments do not include sunlight passing through window glass. This document does not replace ISO 14605.[1] Either document can apply…

This document provides a)    a discussion of alternative experimental designs for the determination of trueness and precision measures including reproducibility, repeatability and selected measures of intermediate precision of a standard measurement method, including a review of the circumstances in which their use is necessary or beneficial, and guidance as to the interpretation and application…

This document specifies the common conventions required for the interchange of specific patient data (demographic, recording conditions ...), ECG signal data and metadata, ECG measurements and ECG annotations, and ECG interpretation results. This document specifies the content and structure of the information which may be interchanged between digital ECG electrocardiographs/devices and computer…
