This document specifies calibration methods for a pyranometer using a pyrheliometer as a reference instrument. Three methods are specified in this document. a)       Alternating sun and shade method. This method uses a shading disc to alternately shade and unshade a pyranometer to compare with the tracking pyrheliometer. The test pyranometer can be horizontal, on a fixed tilt or tracking…

This document specifies a method for the gas chromatographic determination of menthol in the total particulate matter (TPM) of mentholated cigarette mainstream smoke with a smoking regime according to ISO 3308 (standard smoking regime). The smoking of cigarettes and the collection of TPM from the mainstream smoke are carried out in accordance with ISO 4387 with some exceptions (see Annex A).…

This document specifies a method of determining the characteristic fusion temperatures of ash from hard coal. NOTE            Descriptors: fossil fuels, ash, ashes, tests, high temperature tests, determination, and fusibility.

This document specifies ways in which rare earths can be traced as they move through the supply chain between the separated products to rare earth permanent magnets, or otherwise to be further processed. The documented traceability information is applicable to purchasers, suppliers, and users of rare earth permanent magnets to identify parties in the supply chain who have processed a given…

This document specifies: — How to uniquely identify Digital Items (and parts thereof); — How to uniquely identify IP related to the Digital Items (and parts thereof), for example abstractions; — How to express the relationship between the two above identifiers; — How to deal with varying levels of functional granularity for Digital Item identifiers; — How to uniquely identify…

IEC TR 62839-1:2025 describes the product specific rules (PSR) for wires and cables used for communication, data, control and command. These PSR are applicable in case the life cycle assessment (LCA) results are intended to be used in external communication in the form of an environmental product declaration (EPD), as laid out in ISO 14021, ISO 14025, ISO 14026 and ISO 14067. These PSR are…

IEC TS 62586-3:2025 Describes a procedure used for maintenance tests of individual power quality instruments. Users of these instruments need to ensure the conformity of the individual power quality instrument for stationary use with the requirements of IEC 62586‑1. This is achieved by periodic maintenance tests as defined in this document.

IEC TS 63263:2025 describes a test method for evaluating the lifetime of winding wires under electrical high frequency voltage impulses (with partial discharges) at elevated temperatures. This method is only applicable as a comparative examination under a given sample preparation and testing environment. The comparative nature of this document lies in the fact that the lifetime under partial…
