This document specifies experimental procedures and statistical analysis for the determination of measurement uncertainty in situations where the following conditions are fulfilled: Condition 1: The level of the measurand is non-negative, e.g. concentration level of a contaminant in a sample. Condition 2: Measurement error consists of two independent components: for one of these components the…

The purpose of this document is to give an overview of the minimum requirements for performing the dicentric assay with quality control measures using mitogen stimulated peripheral blood lymphocytes for initial assessment of individuals involved in a mass casualty scenario. The dicentric assay is the use of chromosome damage to quickly estimate approximate radiation doses received by individuals…

IEC 62052-41:2022 applies only to newly manufactured multi-energy and/or multi-rate static meters and it applies to their type tests only. This document applies to electricity metering equipment designed to: • measure and control electrical energy on networks with voltage up to 1 000 V AC, or 1 500 V DC; • have all functional elements, including add-on modules, enclosed in, or forming a single…

This document specifies the determination of nickel-59 and nickel-63 (59Ni and 63Ni) activity concentration in samples of all types of water using liquid scintillation counting (LSC). Using currently available liquid scintillation counters, this test method can measure 59Ni activity concentrations of 50 mBq·l−1 and 63Ni activity concentrations of 20 mBq·l−1 with a counting time of 200 min and a…

This document specifies the determination of nickel-59 and nickel-63 (59Ni and 63Ni) activity concentration in samples of all types of water using inductively coupled plasma mass spectrometry (ICP-MS). Using currently available ICP-MS, this test method can measure 59Ni activity concentrations of 300 mBq⋅l−1 and 63Ni activity concentrations of 200 Bq⋅l−1. These values can be achieved with a sample…

This document is focused on the management of the round robin study (RRS) and can provide guidance for the scope development, planning, and execution of the RRS study. It can provide guidance to identify the feedstock, machine operations, process controls, and post-processing operations prior to running the study. RR organizers can identify controlled and free parameters in the study. This…

This document provides detailed descriptions of statistical methods for proficiency testing providers to use to design proficiency testing schemes and to analyse the data obtained from those schemes. This document provides recommendations on the interpretation of proficiency testing data by participants in such proficiency testing schemes and by accreditation bodies. The procedures in this…

IEC TR 61904-10:2022 - is applicable to laboratory standard microphones meeting the requirements of IEC 61094-1 and other types of measurement microphones, - describes one possible absolute method for determining the complex pressure sensitivity, based on a device capable of generating a known sound pressure, especially at low frequencies, and - provides a reproducible and accurate basis for…

1 Scope 1.1 This Standard covers plumbing fixtures made of stainless steel alloys and specifies requirements for materials, construction, performance, testing, and markings. Note: The term “corrosion-resisting steel” is also applied to stainless steel. 1.2 This Standard covers the following plumbing fixtures: a) bathtubs; b) bidets; c) drinking fountains and water coolers; d)…
