This part of IEC 62477 applies to power electronic converter systems (PECS) and equipment, their components for electronic power conversion and electronic power switching, including the means for their control, protection, monitoring and measurement, such as with the main purpose of converting electric power, with rated system voltages up to 36 kV AC or 54 kV DC

This document also applies to PECS which intentionally emit or receive radio waves for the purpose of radio communication.

This document can also be used as a reference standard for product committees producing product standards for

adjustable speed electric power drive systems (PDS),

standalone uninterruptible power systems (UPS), and

stabilized DC power supplies.

For PECS for which no product standard exists, this document provides minimum requirements for safety aspects.

This document has the status of a group safety publication in accordance with IEC Guide 104 for power electronic converter systems and equipment for solar, wind, tidal, wave, fuel cell or similar energy sources.

According to IEC Guide 104, one of the responsibilities of technical committees is, wherever applicable, to make use of basic safety publications and/or group safety publications in the preparation of their product standards.

IEC 62477-1 is applicable within this document unless specifically stated. References to IEC 62477-1 regarding applicability at the clause level do not supersede the requirements specifically highlighted within this document. E.g. a reference to a clause in IEC 62477-1 which references a table in IEC 62477-1, which has been modified for usage within IEC 62477-2, the table in IEC 62477-2 is the superseding table.

This document

establishes a common terminology for safety aspects relating to PECS and equipment,

establishes minimum requirements for the coordination of safety aspects of interrelated parts within a PECS,

establishes a common basis for minimum safety requirements for the PEC portion of products that contain PEC,

specifies requirements to reduce risks of fire, electric shock, thermal, energy and mechanical hazards, during use and operation and, where specifically stated, during service and maintenance,

specifies minimum requirements to reduce risks with respect to pluggable and permanently connected equipment, whether it consists of a system of interconnected units or independent units, subject to installing, operating and maintaining the equipment in the manner prescribed by the manufacturer,

establishes an arc fault rating label requirement with testing instructions for PEC and PECS, and

covers power electronic converters and systems in open type design, which are catalog (pre-defined commercially available) power electronic converters and systems or engineered solutions from same.

This document does not cover

LV PEC and PECS covered solely by IEC 62477-1:2022

telecommunications apparatus other than power supplies to such apparatus,

functional safety aspects as covered by, for example, IEC 61508 (Series),

electrical equipment and systems for railways applications and electric vehicles, and

power electronic converters and systems in open type design, which are – in their major part – dimensioned, designed and constructed according to the user’s individual requirements and specifications and follow power installation standards, for example IEC 61936-1:2021 and IEC 61936-2:2023.

This part of IEC 63567-1 proposes a method of measuring the transmittance of extreme ultraviolet (EUV) pellicle used for extreme ultraviolet lithography (EUVL) and provides guidelines on the conditions of the transmittance measurement instrument using EUV with a short wavelength and methods for calculating EUV transmittance.

The scope of this document applies to all types of membranes attached to the front side of a reflective mask (or reflective reticle) used in EUVL to physically protect the reflective mask from contaminant particles generated inside the chamber during EUV exposure.

IEC 60601-1:2005+AMD1:2012, 1.1 is replaced by:

This document applies to the basic safety and essential performance of a clinical thermometer in combination with its accessories, hereafter referred to as ME equipment. This document specifies the general and technical requirements for electrical clinical thermometers. This document only applies to all electrical clinical thermometers that are used for measuring the temperature of patients.

This document is also applicable to those accessories intended by their manufacturer to be connected to the clinical thermometer, where the characteristics of those accessories can affect the basic safety or essential performance of the clinical thermometer.

EXAMPLE 1         Probes, probe cable extenders and probe covers.

Clinical thermometers can be equipped with interfaces to accommodate secondary indicators, printing equipment, and other auxiliary equipment to create ME systems. This document does not apply to auxiliary equipment.

ME equipment that measures the temperature of a patient is within the scope of this document.

EXAMPLE 2        ME equipment using accessories such as a pulmonary artery catheter for the determination of cardiac output by thermodilution is in the scope of this document if it displays a temperature.

EXAMPLE 3        ME equipment using accessories such as a Foley catheter that includes a temperature probe is in the scope of this document.

This document does not specify requirements for screening thermographs intended to be used for the individual non-invasive human febrile temperature screening of humans under indoor environmental conditions, whose laboratory accuracy requirements are described in IEC 80601‑2‑59[4].

If a clause or subclause is specifically intended to be applicable to ME equipment only, or to ME systems only, the title and content of that clause or subclause will say so. If that is not the case, the clause or subclause applies both to ME equipment and to ME systems, as relevant.

Hazards inherent in the intended physiological function of ME equipment or ME systems within the scope of this document are not covered by specific requirements in this document except in IEC 60601‑1:2005+AMD1:2012, 7.2.13 and 8.4.1.

NOTE              Additional information can be found in IEC 60601–1:2005+AMD1:2012, 4.2.
