IEC 62828-4:2020 establishes specific procedures for testing level transmitters used in measuring and control systems for industrial process and machinery control systems. For general test procedures, reference is to be made to IEC 62828-1:2017, applicable to all types of transmitters.
Throughout this document, the term "industrial transmitters" covers all types of transmitters used in measuring and control systems for industrial processes and for machinery.
The requirements of this document are applicable to all level measurement principles.
Detailed description of transmitters is given for two main principles for improved clarity.

IEC 62828-5:2020 establishes specific procedures for testing flow transmitters used in measuring and control systems for industrial process and for machinery control systems.

This document – together with IEC 62828-1:2017 – is the reference standard for testing every type of flow transmitter, not only for liquids but also for gases and for steam.
In this document, "industrial flow transmitters" consistently covers all types of flow transmitters used in measuring and control systems for industrial process and for machinery.

IEC TR 62967:2018(E) provides guidance on the assurance of reliability data of automation devices. If the source of this data is through calculation, guidance is given on how to specify the methods used for this calculation. If the source is through observations, guidance is given on how to describe these observations and their evaluations. If the source is the outcome of laboratory tests, guidance is given on how to specify these tests and the conditions under which they have been carried out. This document defines the form to present the data.

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”.

IEC 62828-1:2017 establishes a general framework for defining reference conditions and test procedures applicable to all types of industrial and process measurement transmitters (PMTs) used in measuring and control systems for industrial process and machinery. These reference test conditions are divided into “standard reference conditions”, which apply when determining the accuracy of measurement, and “ambient and process reference conditions”, which are used to assess the influence of external quantities on the measurement. The IEC 62828 series cancels and replaces the IEC 60770 series and proposes revisions for the IEC 61298 series.

IEC 62828-2:2017 establishes specific procedures for testing pressure process measurement transmitters (PMT) used in measuring and control systems for industrial processes and for machinery control systems. A pressure PMT can feature a remote seal to bring the process variable to the sensing element in the PMT. When the remote seal cannot be separated from the PMT, the complete device is tested.

This second edition cancels and replaces the first edition published in 2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- use of the term "two- or multi-position output" instead of "two- or multi-state instrument" (see Scope);

This Technical Specification aims at providing background information for developing evaluation methods for microprocessor-based instruments. An evaluation starts with analysis of the instrument in terms of the external and internal information flows from and to the process, the human operator and external systems. Main function blocks in the instrument are then identified. By using the checklists given in 4.2 and 4.3, the functions and properties that may be embedded in the function blocks of the instrument to be evaluated can be identified.
