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…

This document specifies three procedures to test the service life of a blast-cleaning abrasive under laboratory conditions. The performance of an abrasive is also measured by its ability to clean, via transmission of kinetic energy to the substrate in the blasting process. This document also specifies the procedures that can be performed in the same testing machines to help evaluate abrasive…

This document specifies requirements and gives recommendations for the collection, handling, documentation, transport, storage and processing during the pre-examination phase of formalin-fixed and paraffin-embedded (FFPE) tissue specimens intended for qualitative and/or (semi-)quantitative in situ examination of the morphology and of biomolecules, such as metabolites, proteins, DNA and/or RNA, on…

Scope Replacement: This part of IEC 80601 applies to the BASIC SAFETY and ESSENTIAL PERFORMANCE of SCREENING THERMOGRAPHS intended to be used for the individual non-invasive febrile temperature screening of a human under controlled environmental conditions, hereafter referred to as ME EQUIPMENT. This document sets laboratory characterization test limits for the SCREENING THERMOGRAPH. NOTE…

This document specifies two methods for measuring the stiffness and one method for the determination of the flexibility of rubber and plastics hoses and tubing when they are bent to a specific radius at sub-ambient temperatures. Method A is suitable for non-collapsible rubber and plastics hoses and tubing with a bore of up to and including 25 mm. This method provides a means of measuring the…
