This document specifies a method to determine the refractive index of optical glass with the accuracy within 3 × 10-5 at the wavelength range from 365 nm to 2 400 nm by using the V-block refractometer method. While this document can be used for non-glass materials, the user is informed that only optical glass has been considered in the development of this document, and other materials can have…

IEC TR 63362-1:2022(E) establishes guidelines for the application and use of aluminium electrolytic capacitors in electronic equipment. The information given in this document applies to capacitors with non-solid electrolyte but can, in its appropriate clauses, apply to capacitors with solid electrolyte as well. Electrolytic capacitors in general – and aluminium electrolytic capacitors in…

This document specifies a uniform, reproducible testing process for various drive units, chassis, constructions and lifting devices for the refuse collection vehicles described in EN 1501 (all parts, excluding EN 1501-4), with which a comparison for energy consumption can be performed. This specification defines criteria for a reference area with regard to a synthesized tour (test circuit). This…

This document provides guidance to potential users for the specification of the global distribution of ionosphere densities and temperatures, as well as the total content of electrons in the height interval from 50 km to 1 500 km. It includes and explains several options for a plasmaspheric extension of the model, embracing the geographical area between latitudes of 80°S and 80°N and longitudes…

This document specifies an unambiguous scheme to list official organizational roles by jurisdiction in a standard way. It is not the purpose of this document to compare or align official organizational roles across different countries or jurisdictions, so as not to limit the usage or relevance of this document. To understand the powers associated with each official organizational role, users of…

IEC TR 61850-10-3:2022(E), which is a technical report, is applicable to testing of applications within substations. It is intended to give practical guidelines to perform the stages of quality assurance defined in IEC 61850-4:2011. However, while the quality assurance in that document begins with the IED manufacturer development stage and focuses on the role of the system integrator this…

IEC TS 63349-2:2022 defines operation modes of photovoltaic direct-driven appliance (PVDDA) controllers and describes one example of a graphic display. The graphic display is an interface to PVDDA users, which uses easily understood graphics to show a real-time operation mode, such as what equipment is installed, controlled and monitored in the system, which equipment is generating power and how…

1.1 Scope This International Standard is applicable to devices for surge protection of telecommunications and signalling networks against indirect and direct effects of lightning or other transient overvoltages. The purpose of these SPDs is to protect modern electronic equipment connected to telecommunications and signalling networks with nominal system voltages up to 1 000 V (r.m.s.) a.c…

1 Scope 1.1 This Standard specifies the chassis and body requirements and safety equipment requirements for school buses. It is a manufacturing standard intended to apply to original equipment supplied by the bus manufacturer. Note: The main purpose of this Standard is to provide the safest possible vehicle for students using school buses. It needs to be stressed, however, that standards are…

1 Scope 1.1 General This Standard applies to occupational diving, hyperbaric facility, and remotely operated vehicle (ROV) operations conducted in connection with all types of work and employment and describes the requirements for minimum competency levels for all personnel directly associated with the identified techniques of diving or ROV operations. Canadian safety and health legislation…
