Methods for calculating the main static performance indicators of transducers and transmitters
IEC TR 62967:2018(E) provides guidance on the assurance of reliability data of automation devices. If the source of this data is through calculation, guidance is given on how to specify the methods used for this calculation. If the source is through observations, guidance is given on how to describe these observations and their evaluations. If the source is the outcome of laboratory tests,…
This document specifies requirements and test methods for powered polymerization activators in the 380 nm to 515 nm wavelength region intended for chairside use in polymerization of dental polymer-based materials.
This document applies to quartz-tungsten-halogen lamps and light-emitting diode (LED) lamps. Powered polymerization activators could have internal power supply (rechargeable battery…
Determination of the ultimate aerobic biodegradability of plastic materials in an aqueous medium — M...
This document specifies a method, by measuring the amount of carbon dioxide evolved, for the determination of the degree of aerobic biodegradability of plastic materials, including those containing formulation additives. The test material is exposed in a synthetic medium under standardized laboratory conditions to an inoculum from activated sludge, mature compost or soil under aerobic, mesophilic…
Sterilization of health care products — Biological and chemical indicators — Test equipment

Rubber — Framework for assessing the environmental fate of tyre and road wear particles (TRWP)
This document establishes a general framework and considerations for assessing the environmental fate of tyre tread chemical additives in cured polymer and tyre and road wear particles (TRWP) throughout a tyre lifecycle. This document is applicable to laboratory-generated TRWP from cured tread polymer of known composition.
Testing strategies are described for assessing the environmental fate and…
Implants for surgery — Partial and total hip-joint prostheses — Part 10: Determination of resistance...
This document specifies methods of determining the compressive (fracture) or the tension (disassembly) loads required, under specific laboratory conditions, to cause failure of a modular head system.
This document applies to components made of metallic and non-metallic materials, such as femoral heads of partial or total hip-joint replacements of modular construction (i.e. a head/neck conical…
Biotechnology — Biobanking — General requirements for biobanking
This document specifies general requirements for the competence, impartiality and consistent operation of biobanks including quality control requirements to ensure biological material and data collections of appropriate quality.
This document is applicable to all organizations performing biobanking, including biobanking of biological material from multicellular organisms (e.g. human, animal,…
This document defines performance criteria for an optical data channel used in impact tests on road vehicles, when numerical time and space data are taken from images to analyse impact test results.
The objective of this document is to facilitate comparison between results obtained by different laboratories by specifying minimum quality criteria.
Annexes A, B, C and D present a method of…
