IEC 62828-3:2018 establishes specific procedures for testing temperature transmitters used in measuring and control systems for industrial process and for machinery control systems. When the process measurement transmitter features the temperature transmitter separated from the sensing element, the standard applies only to the temperature transmitter without the sensing element. In the case of a device where the sensing element is fully integrated with the temperature transmitter, the standard applies to the complete device. For general test procedures, reference is made to IEC 62828-1, which is applicable to all types of industrial and process measurement transmitters (PMT). The sensing element itself as well as radiation thermometers are excluded from the scope of this document. The IEC 62828 series cancels and replaces the IEC 60770 series and proposes revisions for the IEC 61298 series. NOTE In industrial and process applications to indicate the process measurement transmitters, it is common also to use the terms “industrial transmitters”, or “process transmitters”.

ISO 80601-2-56:2017 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 applies to all electrical clinical thermometers that are used for measuring the body temperature of patients.
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 a body temperature is inside the scope of this document.
ISO 80601-2-56:2017 does not specify the requirements for screening thermographs intended to be used for the individual non-invasive human febrile temperature screening of groups of individual humans under indoor environmental conditions, which are given 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+A1:2012, 7.2.13 and 8.4.1.
NOTE Additional information can be found in IEC 60601?1:2005+A1:2012, 4.2.
