This document provides methods for the testing, calibration and use of volumetric instruments made from glass and plastic in order to obtain the best accuracy in use. NOTE      Testing is the process by which the conformity of the individual volumetric instrument with the appropriate standard is determined, resulting in the determination of its error of measurement at one or more points. This…

This document specifies the neutron reference radiation fields, in the energy range from thermal up to 20 MeV, for calibrating neutron-measuring devices used for radiation protection purposes and for determining their response as a function of neutron energy. This document is concerned only with the methods of producing and characterizing the neutron reference radiation fields. The procedures for…

1 Scope 1.1 General This Standard applies to the reporting of information regarding the conducting of eDNA biological surveys or assessments. This Standard provides a) definitions for terms that are routinely used in the description of eDNA studies; and b) minimum reporting requirements for eDNA studies in a quality assurance/quality control context, including the following: i) survey…

This document specifies requirements and recommendations on the handling, storage, processing and documentation of saliva specimens intended for human DNA examination during the pre-examination phase before a molecular examination is performed. This document is applicable to molecular in vitro diagnostic examination including laboratory developed tests performed by medical laboratories. It can…

IEC 62885-2:2021 is applicable for measurements of the performance of mains-operated dry vacuum cleaners, including water filter vacuum cleaners for household or similar use. The purpose of this document is to specify essential performance characteristics of dry vacuum cleaners which are of interest to users and to describe methods for measuring these characteristics. Due to the influence of…

This document introduces five statistical methods for evaluating the precision of binary measurement methods and their results. The five methods can be divided into two types. Both types are based on measured values provided by each laboratory participating in a collaborative study. In the first type, each laboratory repeatedly measures a single sample. The samples measured by the laboratories…

This document deals with principles of sampling of soil, rock and groundwater as part of the programme of geotechnical investigation and testing. NOTE 1    This document fulfils the requirements for sampling of soil, rock and groundwater, and groundwater measurements as part of the programme of geotechnical investigation and testing according to EN 1997-1 and EN 1997-2. The aims of such ground…

IEC 61753-111-09:2021 contains the minimum tests, test severities and measurement requirements which a sealed fibre optic closure need to meet in order to be categorised as meeting the IEC standard for category S – Subterannean, as defined in Table A.15 of IEC 61753‑1:2018. This first edition cancels and replaces IEC 61753-111-9 published in 2009. This edition constitutes a technical revision.…

IEC 61753-111-07:2021 contains the minimum tests, test severities and measurement requirements which a sealed fibre optic closure need to meet in order to be categorised as meeting the IEC standard for category A – Aerial, as defined in Table A.13 of IEC 61753‑1:2018. Free breathing closures are not covered in this document. This first edition cancels and replaces IEC 61753-111-7 published in…

This document specifies the laboratory test procedure for determining the clamping force exerted by the fastening system on the foot of the rail by measuring the force to separate the rail foot from its immediate support. When required, the procedure is also used to determine the uplift stiffness of the fastening system. It is applicable to systems with and without baseplates on all types of…
