Electrical relays - Tests and measurements - Part 48: Contact failure rate test
IEC 63522-48:2024 is used for for testing electromechanical elementary relays (electromechanical relays, reed relays, reed contacts, reed switches and technology combinations of these) and for evaluating their ability to perform under expected conditions of transportation, storage and all aspects of operational use.
This document defines a standard test method for contact failure rate test of…
Plastics — Methods of exposure to laboratory light sources — Part 4: Open-flame carbon-arc lamps
This document specifies methods for exposing specimens to open-flame carbon-arc lamps in the presence of moisture to reproduce the weathering effects that occur when materials are exposed in actual end-use environments to global solar radiation, or to window-glass filtered solar radiation.
The specimens are exposed to filtered open-flame carbon-arc light under controlled environmental conditions…

Test methods for fibre-reinforced cementitious composites — Load-displacement curve using notched sp...
This document specifies the test method for the load-displacement curves of fibre-reinforced cementitious composites (FRCC) by three-point loading of notched prisms. The main purpose of this test is to evaluate the tension softening curve of FRCC.
NOTE 1       Both crack mouth opening displacement (CMOD) and load point displacement (LPD) are specified as the displacement in load-displacement…
Biotechnology — Biobanking — Requirements for human neural stem cells derived from pluripotent stem ...
This document specifies requirements for the biobanking of human neural stem cells (hPSC-NSCs) derived from human pluripotent stem cells (hPSCs), including the requirements for the differentiaton, culture, characterization, quality control (QC), storage, thawing and transport of hPSC-NSCs.
Requirements for the collection of biological source material, the transport to and reception of biological…
Water quality — Radium-226 — Part 3: Test method using coprecipitation and gamma-ray spectrometry
This document specifies a method to determine radium-226 (226Ra) activity concentration in all types of water by coprecipitation followed by gamma-ray spectrometry (see ISO 20042[7]).
The method covers the measurement of soluble 226Ra activity concentrations greater than 0,002 Bq·l−1 using a sample volume of up to 100 l of any water type.
For water samples with a volume of less than a volume of 1…
