This document applies to the performance testing of compressor driven refrigerating systems (hereafter referred to as refrigerating systems) that operate according to the principle of vapour compression and consist of the circuit parts for compression, condensation, and evaporation as well as the connecting pipes and any necessary associated ancillaries required for a complete refrigeration…

This document specifies the metrological and technical requirements for flowmeters intended to be used for the dynamic measurement of liquefied natural gas (LNG) and other refrigerated hydrocarbon fluids. For LNG static volume measurement used in custody transfer, see ISO 10976. This document sets the best practice for the proper selection and installation of flowmeters in cryogenic applications…

IEC 63164-1:2020(E) provides guidance on the assurance of reliability data of automation devices. If the source of this data is calculation, guidance is given on how to specify the methods used for this calculation. If the source is from observation of devices in the field, guidance is given on how to describe these observations and their evaluations. If the source is the outcome of laboratory…

This document describes tools and gives guidance concerning interlaboratory trials related to fire effluent analyses. It explains the relative contributions from the physical fire model and analytical techniques to evaluate trueness and fidelity. It also explains the difficulties involved with the interpretation of round-robin data and with the evaluation of trueness in fire effluent analyses.…

This document establishes requirements for the use of the glass designations "clear glass" and "ultra-clear glass" for non-coloured glass items according to their clarity and iron content. It specifies a procedure for measuring the clarity of glass items by means of a spectrophotometer. This document is applicable to — mineral glasses, and — glass items where a part is…

This document defines a global approach for the validation of a quantitative analytical method, based on the construction and interpretation of an accuracy profile, and specifies its characterization procedure. This procedure is particularly applicable for internal validation in a cosmetic testing laboratory, but its scope can be extended to the interpretation of data collected for an…

This document provides principles for characterizing the measured production of toxic gases from a laboratory fire test and provides bases for comparing the results between different types and scales of such tests. It also includes consideration of the uncertainties in the gas determinations. The combined uncertainty is a key factor in the ability to establish similarity or difference of test…

This document specifies a framework for the identification, and if necessary, quantification of constituents of a medical device, allowing the identification of biological hazards and the estimation and control of biological risks from material constituents, using a generally stepwise approach to the chemical characterization which can include one or more of the following: — the…

IEC 61322:2020 applies to installed dose equivalent rate meters, warning assemblies and monitors, as defined below. It covers equipment intended to measure neutron radiation in dose equivalent rates in the energy region between thermal and 20 MeV for the purposes of radiation protection. Assemblies of this type are commonly defined as area radiation monitors. They are normally employed to…

This document establishes rules and conventions for particular use with technical drawings on glassware, for example, laboratory glassware or glassware used in other technical fields. Optical parts are not, however, included herein.
