Industrial process control systems - Methods of evaluating the performance of valve positioners with pneumatic outputs - Part 2: Test Methods for intelligent positioners mounted on an actuator valve assembly
Käsitlusala: IEC 61514-2:2026 specifies design reviews and tests intended to measure and determine the static and dynamic performance, the degree of intelligence and the communication capabilities of single-acting or double-acting intelligent valve positioners. The tests can be applied to positioners which receive standard analogue electrical input signals (as specified in IEC 60381-1 or IEC 60381-2) and/or digital signals via a data communication link (for example Fieldbus) and have a pneumatic output. An intelligent valve positioner as defined in Clause 3 is an instrument that uses for performing its functions digital techniques for data processing, decision-making and bi-directional communication. It can be equipped with additional sensors and additional functionality supporting the main function. The performance testing of an intelligent valve positioner is conducted with the positioner mounted on and connected to the actuator/valve assembly the positioner is used on. The specific characteristic parameters of the actuator/valve combination such as size, stroke, friction, type of packing, spring package and supply pressure for the pneumatic part has significant impact on the performance of a positioner. The methods of evaluation given in this document are intended for testing laboratories to verify equipment performance specifications. The manufacturers of intelligent positioners are urged to apply this document at an early stage of development.
This document is intended to provide guidance for designing evaluations of intelligent valve positioners by providing:
- a checklist for reviewing their hardware and software design in a structured way;
- test methods for measuring and qualifying their performance under various environmental and operational conditions;
- methods for reporting the data obtained.
When a full evaluation, in accordance with this document, is not required or possible, the tests which are required are performed and the results reported in accordance with the relevant clauses of this document. In such cases, the test report will state that it does not cover the full number of tests specified herein. Furthermore, the items omitted are mentioned, to give the reader of the report a clear overview. This document is also applicable for non-intelligent microprocessor-based valve positioners without means for bi-directional communication. In that case an evaluation will be reduced to a limited programme of performance testing and a review of the construction. This third edition cancels and replaces the second edition published in 2013. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) in 5.5.2, the standard for the measurements of influence quantities has been changed to IEC 62828-1:2026;
b) all references to IEC 61514 have been updated to IEC 61514:2026;
c) the aspect of cyber-security has been added in 4.2.7 and 4.2.9.
This document is to be used in conjunction with IEC 61514:2026.

Käsitlusala: IEC TS 63086-2-5:2026 specifies test methods for measuring the performance change of electrically powered household and similar air cleaners caused by the loading with particles.
The main intention of the document is to compare differences in the performance change between air cleaners exposed to the same loading with particles. The performance change is not necessarily representative for real-use applications since concentration, size, morphology and chemical composition of particles present in household or similar environments can strongly differ.

Käsitlusala: IEC 61514-2:2013 specifies design reviews and tests intended to measure and determine the static and dynamic performance, the degree of intelligence and the communication capabilities of single-acting or double-acting intelligent valve positioners. The tests may be applied to positioners which receive standard analogue electrical input signals (as specified in IEC 60381) and/or digital signals via a data communication link and have a pneumatic output. This second edition cancels and replaces the first edition published in 2004 and constitutes a technical revision. The significant changes with respect to the previous edition are: The standard has been optimized for usability and the test procedures have been reviewed regarding applicability for use in test facilities. Impractical test procedures were removed or modified.

Vacuum technology -- Vacuum gauges -- Evaluation of the uncertainties of results of calibrations by direct comparison with a reference gauge
Käsitlusala: ISO 27893:2011 gives guidelines for the determination and reporting of measurement uncertainties arising during vacuum gauge calibration by direct comparison with a reference gauge carried out in accordance with ISO/TS 3567.
ISO 27893:2011 describes methods for uniform reporting of uncertainties in vacuum gauge certificates. Uncertainties reported in accordance with the guidelines given in ISO 27893:2011 are transferable in the sense that the uncertainty evaluated for one result can be used as a component in the uncertainty evaluation of another measurement or calibration in which the first result is used.
ISO 27893:2011 defines two measurement models that are sufficient to cover most practical cases. However, it is possible that the models given cannot be applied to newly developed vacuum gauges.

Design of fans working in potentially explosive atmospheres
Käsitlusala: 1.1 This document specifies the constructional requirements for fans constructed to Group II G (of explosion groups IIA, IIB and hydrogen) categories 1, 2 and 3, and Group II D categories 2 and 3, intended for use in explosive atmospheres.
NOTE 1 Operation conditions for the different categories of fans used in this document are defined in Clause 4.
1.3 This document specifies requirements for design, construction, testing and marking of complete fan units intended for use in potentially explosive atmospheres in air containing gas, vapour, mist and/or dusts. Such atmospheres can exist inside (the conveyed atmosphere (flammable or not)), outside, or inside and outside of the fan.
This document covers mechanical equipment, in particular fans. The “type of protection” as specified in EN ISO 80079 37:2016 is constructional safety.
1.4 This document is applicable to fans working in ambient atmospheres and with normal atmospheric conditions at the inlet, having
— absolute pressures ranging from 0,8 bar to 1,1 bar,
— and temperatures ranging from −20 °C to +60 °C,
— and maximum volume fraction of 21 % oxygen content,
— and an aerodynamic energy increase of less than 25 kJ/kg.
NOTE 1 25 kJ/kg is equivalent to 30 kPa at inlet density of 1,2 kg/m3.
This document can also be helpful for the design, construction, testing and marking of fans intended for use in atmospheres outside the validity range stated above or in cases where other material pairings need to be used. In this case, the ignition risk assessment, ignition protection provided, additional testing (if necessary), manufacturer's marking, technical documentation and instructions to the user, clearly demonstrate and indicate the equipment's suitability for the conditions the fan can encounter.
NOTE 2 Temperatures below −20 °C can be considered. Material suitability can require specific evaluation for these temperatures. With lower temperature the explosion pressure increases, which leads to increased test pressures (see A.3) and can require specific testing. Although the standard atmospheric conditions in EN ISO 80079 36:2016 give a temperature range for the atmosphere of −20 °C to +60 °C the normal ambient temperature range for the equipment is −20 °C to +40 °C unless otherwise specified and marked.
1.5 This document does not apply to:
— group I fans (fans for mining);
— explosion group IIC (other than hydrogen);
— category 1D fans;
— cooling fans or impellers on rotating electrical machines;
— cooling fans or impellers on internal combustion engines, vehicles or electric motors.
