Safety of toys — Part 1: Safety aspects related to mechanical and physical properties
The requirements in this document apply to all toys, i.e. any product designed or clearly intended for use in play by children under 14 years of age. They are applicable to a toy as it is initially received by the consumer and, in addition, they apply after a toy is subjected to reasonably foreseeable conditions of normal use and abuse unless specifically noted otherwise.
The requirements of this…
Connectors for electrical and electronic equipment - Part 5: Detail specification for 2-way M8 and M...
IEC 63171-5:2022 refers to International Standards for test and measurement, environmental testing as well as solderless connections. This part of IEC 63171 describes 2-way shielded or unshielded circular connectors with IP65/IP67 M8 or M12 locking, typically used for balanced single-pair data transmission with frequencies up to 600 MHz and with current-carrying capacity up to 4 A, for use in…
Fibre optic interconnecting devices and passive components - Connector optical interfaces for single...
IEC 61755-1:2022 covers dispersion unshifted single-mode fibre optic connection interfaces. It includes references, document structure details, definitions, and standardised optical connection grades. The grades are based on random mated connections between two optical connector populations according to required characteristics including fibre mode field diameter (MFD) mismatch. It also defines…
Fibre optic interconnecting devices and passive components - Connector optical interfaces for single...
IEC 61755-2-2:2022 defines a set of prescribed conditions for a single-mode fibre optic connection that is maintained in order to satisfy the requirements of attenuation and return loss (RL) performance in a randomly mated pair of angled polished physically contacting (APC) fibres. The model uses a Gaussian distribution of light intensity over the specified mode field diameter (MFD) for…
Intelligent transport systems — Guided transportation service planning data exchange
This document specifies an open, XML-based data format which enables an efficient and unambiguous exchange of static information concerning the operational functionality of the infrastructure, rolling stock and timetable of a track-bound transportation system. The main objective is to enable heterogeneous railway applications to communicate with each other.
The purpose of the data format is to…
Intelligent transport systems — Roadside modules SNMP data interface — Part 6: Commands
Field devices are a key component in intelligent transport systems (ITS). Field devices include traffic signals, message signs, weather stations, traffic sensors, roadside equipment for connected ITS (C-ITS) environments, etc.
Field devices often need to exchange information with other external entities (managers). Field devices can be quite complex, necessitating the standardization of many data…
Stationary source emissions — Determination of the mass concentration of nitrogen oxides in flue gas...
This document specifies a method for the determination of nitrogen oxides (NOx) in flue gas of stationary sources and describes the fundamental structure and the key performance characteristics of automated measuring systems.
The method allows continuous monitoring with permanently installed measuring systems of NOx emissions.
This document describes extractive systems and in situ (non-extractive…
Dentistry — Mobile dental units and dental patient chairs — Part 2: Air, water, suction and wastewat...
This document specifies the requirements and test methods for mobile dental units concerning:
a) the properties of mobile dental unit connections to the compressed air supply, water supply, suction supply, and wastewater drain plumbing,
b) the materials, design, and construction of the compressed air and water system within the mobile dental unit,
c) the quality for incoming water and air,
d) the…
Fire detection and alarm systems — Part 31: Resettable line-type heat detectors
This document applies to resettable line-type heat detectors consisting of a sensing element distributed either continuously or discretely at close intervals along its length and connected to a sensor control unit, either directly or through an interface module, intended for use in fire detection and fire alarm systems installed in and around buildings and other civil engineering works. Examples…
Wind energy generation systems - Part 12-1: Power performance measurements of electricity producing ...
IEC 61400-12-1:2022 specifies a procedure for measuring the power performance characteristics of a single wind turbine and applies to the testing of wind turbines of all types and sizes connected to the electrical power network. In addition, this document defines a procedure to be used to determine the power performance characteristics of small wind turbines (as defined in IEC 61400-2) when…
