IEC 63093-4:2019 specifies the dimensions that are of importance for mechanical interchangeability for a preferred range of RM-cores and low-profile RM-cores made of ferrite, and the locations of their terminal pins on a 2,54 mm printed wiring grid in relation to the base outlines of the cores. It also gives guidance on allowable limits of surface irregularities applicable to RM-cores in…

This document provides a list of all ISO geometrical product specification (GPS) and technical product documentation (TPD) standards for technical product specifications (TPS) in the mechanical engineering field. The document operates as an index to the many ISO standards applicable to a TPS by means of cross-reference, and, where appropriate, the subject references are supplemented by commentary…

The purpose of ISO/TS 18864:2017 is to define objective, reliable and reproducible quality metrics for detailed clinical models (DCM). ISO/TS 18864:2017 specifies the principal metrics which are necessary and sufficient to evaluate DCMs. The intended audiences of this document are: - DCM developers, all users of information represented using DCMs, and evaluators of DCM quality; -…

CISPR TR 18-2:2017 which is a Technical Report, applies to radio noise from overhead power lines and high-voltage equipment which may cause interference to radio reception. The frequency range covered by this publication is 0,15 MHz to 3 GHz. A general procedure for establishing the limits of the radio noise field from the power lines and equipment is recommended, together with typical values as…

1.1 General This part of the IEC 62443 series is a technical specification which defines the terminology, concepts and models for Industrial Automation and Control Systems (IACS) security. It establishes the basis for the remaining standards in the IEC 62443 series. To fully articulate the systems and components the IEC 62443 series address, the range of coverage may be defined and understood…

ISO 9836:2017 specifies the definition and calculation of surface area and volume indicators. In defining area measurement, ISO 9836:2017 uses three measurement concepts: a) the intra-muros and extra-muros concept used in many parts of the world; b) the wall centre method of measurement used in many parts of the world; c) variations on these methods to comply with certain national laws…
