IEC 61744:2023 provides standard procedures for the calibration of optical fibre chromatic dispersion (CD) test sets. This document is applicable to all types of CD test sets, with the exception that measurements on multimode optical fibres are excluded. The purpose of this document is to define a standard procedure for calibrating optical fibre chromatic dispersion (CD) test sets. The detailed…

This document specifies general requirements for proficiency tests that are offered to in vivo bioassay measurement facilities operating a whole-body counter (WBC) or partial body counter (PBC) for monitoring of persons. It specifies minimum requirements for proficiency testing applicable to dosimetry laboratories that have dedicated facilities for in vivo monitoring and where accreditation is…

IEC 62246-4:2023 gives additional requirements for the evaluation of functional characteristics on reed switching components operated by magnetic actuator and gives guidance for their implementation in selected applications. This document specifies test and measurement procedures for the application of reed switch (contact) based magnetic sensors. In case the application of a reed contact…

This document specifies an apparatus and the procedures for the laboratory wet disintegration of mechanical pulps that exhibit latency except when brightness is measured. This apparatus and procedure can be used for preparation of the test portion in other International Standards dealing with pulps. This document is applicable to all kind of mechanical pulps (i.e. mechanical, semi-chemical and…

IEC TS 63202-3:2023 describes procedures for the measurement of current-voltage (I-V) characteristics of crystalline silicon bifacial photovoltaic (PV) cells for both laboratory and mass production applications. This document is intended to be used for measurement of individual unencapsulated bifacial PV cells, in addition to the requirements described in IEC 60904-1 and differentiating from IEC…

This document specifies a method for determining the amount of material passing through a sieve with 3,15-mm-diameter round holes. It is intended for use in all applications (e.g. laboratories, production sites, field locations) where the measurement of fines is required.

This standard specifies the procedure to determine the relation between the water content and the dry density of soil and soil aggregates mixes when they are compacted in a standard mould by a 2.495 kg rammer dropped from a height of 305 mm. Three methods are used to determine this relation (see Chapter 5). NOTE — The laboratory compaction test methods described in this standard generally…

This standard specifies a procedure to determine the relation between the water content and the dry density of soil and soil aggregates mixes when they are compacted in a standard mould by a 4.536 kg rammer dropped from a height of 457 mm. Three methods are used to determine this relation (see Chapter 5). NOTE — The laboratory compaction test methods described in this standard generally provide…
