NOTE Throughout this standard, the abbreviation ACS (ASSEMBLY for construction site, see 3.1.101) is used for a low-voltage switchgear and controlgear assembly intended for use on construction and similar sites. This part of 61439 defines the specific requirements of ACS as follows: - ASSEMBLIES for which the rated voltage does not exceed 1 000 V in case of AC or 1 500 V in case of DC; - ASSEMBLIES where the nominal primary voltage and the nominal secondary voltage of transformers incorporated in ACS are within the limits specified above; - ASSEMBLIES intended for use on construction sites, both indoors and outdoors, i.e. temporary places of work to which the public do not generally have access and where building construction, installation, repairs, alteration or demolition of property (buildings) or civil engineering (public works) or excavation or any other similar operations are carried out; - transportable (semi-fixed) or mobile ASSEMBLIES with enclosure. The manufacture and/or assembly may be carried out other than by the original manufacturer. This standard does not apply to individual devices and self-contained components, such as motor starters, fuse switches, electronic equipment, etc. which will comply with the relevant product standards. This standard does not apply to ASSEMBLIES for use in the administrative centres of construction sites (offices, cloakrooms, ASSEMBLY rooms, canteens, restaurants, dormitories, toilets, etc.). Requirements for electrical protection provided by equipment manufactured according to this International Standard are given in IEC 60364-7-704.

This document specifies a common technical specification for RFID devices that can be used to develop standards for applications using this radio identification (RAIN) air interface. This document is intended to improve compatibility and encourage inter-operability of products for the growing RFID market in the international marketplace. This document establishes the forward and return link parameters for technical attributes including, but not limited to, operating frequency, operating channel accuracy, occupied channel bandwidth, maximum effective isotropic radiated power (EIRP), spurious emissions, modulation, duty cycle, data coding, bit rate, bit rate accuracy, bit transmission order, and, where appropriate, operating channels, frequency hop rate, hop sequence, spreading sequence, and chip rate. This document further specifies the communications protocol used in the air interface. This document describes the physical and logical requirements for a passive backscatter, Interrogator-talks-first (ITF), radio frequency identification system operating in the 860 MHz to 930 MHz frequency range. This document specifies: physical interactions (the signalling layer of the communication link) between Interrogators and Tags; logical operating procedures and commands between Interrogators and Tags; the collision arbitration scheme used to identify a specific tag in a multiple-tag environment; optional security commands that allow the use of crypto suites of ISO/IEC 29167-1:2014.

IEC 60115-8-10:2026 is applicable to the drafting of detail specifications for surface mount (SMD) low-power film resistors, classified to level G, based on the definition of the product classification levels in IEC 60115‑1:2020, 3.4. This edition includes the following significant technical changes with respect to the previous edition IEC 60115‑8‑1:2014: a) it supports solderability testing for both traditional lead-bearing soldering and up-to-date lead-free soldering, as required; b) it supports the provision of detailed visual acceptance criteria; c) it includes the requirement for a visual examination of the primary and proximity packaging; d) it provides for the inclusion of specific visual acceptance criteria, to be applied in addition to those given in Annex B of the sectional specification IEC 60115‑8:2023.

This document establishes general principles for the measurement and evaluation of vibration using measurements made on rotating or non-rotating parts of complete machines. It is applicable to vibration measurements on non-rotating parts and to both absolute and relative radial shaft vibration with regard to the monitoring of radial clearances, but does not apply to axial shaft vibration, unless otherwise stated. The evaluation criteria, which are presented in terms of both vibration magnitude and change in vibration, relate to both operational monitoring and acceptance tests. They have been provided primarily with regard to securing reliable, safe, long-term operation of the machine while minimizing any adverse effects on associated equipment. This document also gives guidance on setting operating limits. NOTE 1 The evaluation criteria for different machine types are included in other parts of the ISO 10816 series and the ISO 20816 series. NOTE 2 The term “shaft vibration” is used throughout the ISO 10816 series and the ISO 20816 series because, in most cases, vibration measurements are made on machine shafts. However, the ISO 10816 series and the ISO 20816 series are also applicable to measurements made on other rotating elements of the machine if such elements are found or known to be more suitable, provided that the guidelines set in this document are met. The evaluation criteria are only applicable to the vibration produced by the machine itself and not the vibration transmitted to it from outside. This document does not apply to torsional vibration. NOTE 3 For information regarding the evaluation of torsional vibration, see e.g. ISO 3046-5, ISO 22266-1 or VDI 2039.
