Workplace Atmospheres - Part 1: Gas detectors - Performance requirements of detectors for toxic gases
EN IEC 62990-1:2022/A11:2022

This part of IEC 62990 specifies general requirements for design, function and performance, and describes the test methods that apply to portable, transportable, and fixed equipment for the detection and concentration measurement of toxic gases and vapours in workplace atmospheres and other industrial and commercial applications. This document is applicable to continuously sensing equipment whose primary purpose is to provide an indication, alarm and/or other output function the purpose of which is to indicate the presence of a toxic gas or vapour in the atmosphere and in some cases to initiate automatic or manual protective action(s). It is applicable to equipment in which the sensor generates an electrical signal when gas is present.
This document applies to two types of equipment:
• Type HM (Health Monitoring) ‘occupational exposure’ equipment: For occupational exposure measurement, the performance requirements are focused on uncertainty of measurement of gas concentrations in the region of Occupational Exposure Limit Values (OELV). The upper limit of measurement will be defined by the manufacturer in accordance with 4.2.1.
• Type SM (Safety Monitoring) ‘general gas detection’ equipment: For general gas detection applications (e.g. safety warning, leak detection), the performance requirements are focused on alarm signalling. The upper limit of measurement will be defined by the manufacturer according to the intended use of the equipment. In general, the requirements for accuracy will be higher for Type HM equipment than for Type SM equipment. The same equipment may meet the requirements of both Type HM and Type SM. For equipment used for sensing the presence of multiple gases this document applies only to the detection of toxic gas or vapour.
This document is not applicable to equipment:
- with samplers and concentrators such as sorbents or paper tape having an irreversible indication;
- used for the measurement of gases and vapours related to the risk of explosion;
- used for the measurement of oxygen; – used only in laboratories for analysis or measurement;
- used only for process measurement purposes;
- used in the domestic environment;
- used in environmental air pollution monitoring;
- used for open-path (line of sight) area gas measurement;
- used for ventilation control in car parks or tunnels.

Electrical apparatus for the detection and measurement of oxygen - Performance requirements and test methods
EN 50104:2019

This European Standard specifies general requirements for construction, testing and performance, and describes the test methods that apply to portable, transportable and fixed apparatus for the measurement of the oxygen concentration in gas mixtures indicating up to 25 % (v/v). The apparatus, or parts thereof, may be intended for use in potentially explosive atmospheres (see 4.1) and in mines susceptible to firedamp. In the case of inert gas purging (inertization), it applies also to apparatus with an oxygen measuring function for explosion protection. NOTE Commonly used oxygen sensors in commercial equipment for industrial application are: a) paramagnetic sensors; b) electrochemical sensors (aqueous and solid electrolytes); c) tunable diode laser absorption spectroscopy sensors (TDLAS). This standard is also applicable when an apparatus manufacturer makes any claims regarding any special features of construction or superior performance that exceed the minimum requirements of this standard. All such claims shall be verified and the test procedures shall be extended or supplemented, where necessary, to verify the claimed performance. The additional tests shall be agreed between the manufacturer and test laboratory and identified and described in the test report. This European Standard is applicable to oxygen alarm apparatus intended to measure reliably the oxygen concentration, to provide an indication, alarm or other output function, the purpose of which is to give a warning of a potential hazard and, in some cases, to initiate automatic or manual protective action(s), whenever the level exceeds or falls below a preselected alarm concentration. This standard is applicable to apparatus, including integral sampling systems of aspirated apparatus, intended to be used for commercial, industrial and non-residential safety applications. This standard does not apply to external sampling systems, or to apparatus of laboratory or scientific type, or to medical equipment, or to apparatus used only for process control purposes. For apparatus used for sensing the presence of multiple gases, this standard applies only to the measurement of oxygen. This standard is also applicable to apparatus using optical principles (e.g. TDLAS), where the optical transmitter and receiver or the optical transceiver (i.e. combined transmitter and receiver) and a suitable reflector are not located in a common enclosure. However, in this case it will be necessary to modify the test conditions described in Clause 5 and to introduce supplementary tests to Clause 6 of this standard. Such supplementary tests will include alignment, beam block fault, long range operation. Guidance to appropriate modification of the test conditions and supplementary tests may be taken from EN 60079 29 4. Modifications of the test conditions as well as modified and supplementary tests shall be agreed between the manufacturer and test laboratory and identified and described in the test report.

SIST EN 50402:2017(Main)
Electrical apparatus for the detection and measurement of combustible or toxic gases or vapours or of oxygen - Requirements on the functional safety of gas detection systems
EN 50402:2017

This European Standard is applicable to apparatus and systems for the detection and measurement of flammable or toxic gases or vapours or oxygen.
This European Standard is a product standard which is based on EN 61508 (all parts) and for gas detection systems covers both low and high demand mode at SIL capabilities of 1, 2 or 3 only. Gas detection apparatus and gas detection systems are developed as generic products. This standard covers part of the phase 10 “realisation” of the overall safety lifecycle defined in Figure 2 of EN 61508-1:2010. Configuration and integration into specific applications is not covered by this standard.
In the event of conflict between the requirements of this standard and those of EN 61508, EN 50402 will take precedence.
NOTE 1   Applications requiring a SIL capability of 4 for a gas detection system are not practicable.
NOTE 2   This European Standard is dedicated mainly to fixed apparatus. For portable gas detectors claiming a SIL higher than 1, this European Standard may be applied.
This European Standard supplements the requirements of the European Standards for electrical apparatus for the detection and measurement of flammable gases, vapours (e.g. EN 60079-29-1 or EN 60079-29-4), toxic gases (e.g. EN 45544) or oxygen (e.g. EN 50104).
NOTE 3   These European Standards are called in the text "metrological standards".
The examples above show the state of the standardisation for industrial applications at the time of publishing this European Standard. There may be other metrological standards covering other application fields, for which this European Standard is also applicable.
EN 50271 specifies minimum requirements for apparatus using software and/or digital components. It also defines additional optional requirements for compliance with SIL 1 in low demand mode operation. EN 50402 includes all requirements of EN 50271.
EN 50402 is also dedicated to apparatus and gas detection systems and/or components and should be used instead of EN 50271 in the following cases:
-   At SIL 1 when the system contains components not covered by EN 50271;
-   At SIL 2 and SIL 3;
-   At all SILs when non-digital based apparatus is used.
Applying the above-mentioned metrological standards will ensure the measuring performance is adequate in normal operation of a gas detection system. Additionally the requirements of this European Standard address the functional safety of gas detection systems and encompass criteria for reliability, fault tolerance and avoidance of systematic failures. The avoidance and control of systematic failures will be covered by the requirements for the development processes and techniques and diagnostic measures chosen in the design. This European Standard will lead to the characterisation of the gas detection system by a SIL-capability and related hardware failure rate representing a hierarchical order of safety levels. This will allow the user to incorporate the gas detection system into an overall safety system according to the safety integrity levels of EN 61508 (all parts).
This European Standard is applicable for gas detection systems, which may consist of the following functional units:
-   gas-sampling;
-   sensor;
-   signal transmission;
-   input to control unit;
-   signal processing in control unit;
-   output from control unit.
This European Standard does not specify requirements for the installation and maintenance of gas detection systems. It also does not specify the physical positioning of measuring points / locations.
This European Standard does not specify which SIL-capability is sufficient for which application.
NOTE 4   The SIL-capability required for an application will be specified by the user (see Clause 9 and Annex A ).

Explosive atmospheres - Part 29-1: Gas detectors - Performance requirements of detectors for flammable gases (IEC 60079-29-1:2016 , modified)
EN 60079-29-1:2016

This part of IEC 60079-29 specifies general requirements for construction, testing and
performance, and describes the test methods that apply to portable, transportable and fixed
equipment for the detection and measurement of flammable gas or vapour concentrations with
air. The equipment, or parts thereof, is intended for use in explosive atmospheres and in
mines susceptible to firedamp.
This part of IEC 60079-29 is applicable to flammable gas detection equipment with a
measuring range up to any volume fraction as declared by the manufacturer, and which is
intended to provide an indication, alarm or other output function; the purpose of which is to
indicate a potential explosion hazard and in some cases, to initiate automatic or manual
protective action(s).
For the purposes of this part of IEC 60079-29, the term “indicating up to a volume fraction of
X % or X %LFL” includes equipment with an upper limit of the measuring range equal to or
less than X % or X %LFL.
This part of IEC 60079-29 is applicable to equipment, including the integral sampling systems
of aspirated equipment, intended to be used for commercial, industrial and non-residential
safety applications.
This part of IEC 60079-29 does not apply to external sampling systems, or to equipment of
laboratory or scientific type, or to equipment used only for process monitoring and/or control
purposes. It also does not apply to open path (line of sight) detectors which are within the
scope of IEC 60079-29-4. Only equipment with very short optical paths intended for use
where the concentration is uniform over the optical path are within the scope of this standard.
For equipment used for sensing the presence of multiple gases, this part of IEC 60079-29
applies only to the detection of flammable gas or vapour.
This part of IEC 60079-29 supplements and modifies the general requirements of
IEC 60079-0. Where a requirement of this standard conflicts with a requirement of
IEC 60079-0, the requirement of IEC 60079-29-1 takes precedence.
NOTE 1 IEC 60079-29-1 is intended to provide for the supply of equipment giving a level of safety and
performance suitable for general purpose applications. However, for specific applications, a prospective purchaser
(or an appropriate authority) can additionally require the equipment to be submitted to particular tests or approval.
For example, Group I equipment (i.e. equipment to be used in mines susceptible to firedamp) might not be
permitted to be used without the additional, prior approval of the relevant authority in mines under its jurisdiction.
Such particular tests/approval are to be regarded as additional to and separate from the provisions of the
standards referred to above and do not preclude certification to or compliance with these standards.
NOTE 2 All equipment calibrated on specific gases or vapours can not be expected to correctly indicate on other
gases or vapours.
For the purposes of this standard, the terms "lower flammable limit (LFL)" and "lower
explosive limit (LEL)" are deemed to be synonymous, and likewise the terms "upper
flammable limit (UFL)" and "upper explosive limit (UEL)" are deemed to be synonymous. For
ease of reference, the two abbreviations LFL and UFL may be used hereinafter to denote
these two sets of terms. It should be recognized that particular authorities having jurisdiction
may have overriding requirements that dictate the use of one of these sets of terms and not
the other.

Explosive atmospheres - Part 29-2: Gas detectors - Selection, installation, use and maintenance of detectors for flammable gases and oxygen (IEC 60079-29-2:2015)
EN 60079-29-2:2015

This part of IEC 60079-29 gives guidance on, and recommended practice for, the selection,
installation, safe use and maintenance of electrically operated Group II equipment intended
for use in industrial and commercial safety applications and Group I equipment in
underground coal mines for the detection and measurement of flammable gases complying
with the requirements of IEC 60079-29-1 or IEC 60079-29-4.
This standard is applicable for oxygen measurement for the purpose of inertisation where
explosion protection is provided by the exclusion of oxygen instead of measuring the
flammable gases or vapours present. A similar application is measuring oxygen when
inertising a goaf (mined out) area in an underground coal mine.
This standard is a compilation of practical knowledge to assist the user, and applies to
equipment, instruments and systems that indicate the presence of a flammable or potentially
explosive mixture of gas or vapour with air by using an electrical signal from a gas sensor to
produce a meter reading, to activate a visual or audible pre-set alarm or other device, or any
combination of these.
Such equipment may be used as a means of reducing the risk whenever there is the
possibility of a risk to life or property specifically due to the accumulation of a flammable gasair
mixture, by providing such warnings. It may also be used to initiate specific safety
precautions (e.g. plant shutdown, evacuation, fire extinguishing procedures).
This standard is applicable to fixed installations and transportable equipment. Similarly it is
applicable to the safe use of portable equipment. Since much modern equipment of this type
also includes oxygen deficiency detection and/or specific toxic gas sensors, some additional
guidance is given for these topics.
For the purposes of this standard, except where specifically stated otherwise, flammable
gases include flammable vapours.
Mists are not covered by this standard due to measurement techniques currently used.
This standard applies to Group II equipment (i.e. equipment intended for use in industrial and
commercial safety applications, involving areas classified in accordance with IEC 60079-10-1)
and Group I equipment.
For the purposes of this standard, equipment includes
a) fixed equipment including equipment mounted on a vehicle;
b) transportable equipment; and
c) portable equipment.
This standard is not intended to cover, but may provide useful information, for the following:
a) equipment intended only for the detection of non-flammable toxic gases;
b) equipment of laboratory or scientific type intended only for analysis or measurement
purposes;
c) equipment intended only for process control applications;
d) equipment intended for applications in explosives processing and manufacture;
e) equipment intended for the detection of a explosive atmosphere resulting from dust or
mist in air.

Explosive atmospheres - Part 29-3: Gas detectors - Guidance on functional safety of fixed gas detection systems ( IEC 60079-29-3:2014)
EN 60079-29-3:2014

EN IEC 60079-29-3 gives guidance for the design and implementation of a fixed gas detection system, including associated and/or peripheral gas detection equipment, for the detection of flammable gases/vapours and Oxygen when used in a safety-related application in accordance with IEC 61508 and IEC 61511. This International standard also applies to the detection of toxic gases. Other parts of this international standard and pertinent local, national and international standards separately specify the performance requirements of a gas detector and a gas detection control unit (logic solver). These standards are commonly known as Metrological Performance Standards and are concerned with the accuracy of the measured value, the overall system performance, but not the device or system integrity with respect to the safety function. This international standard applies to the integrity of the safety function. This international standard sets out safety-related considerations of fixed gas detection systems, including associated and/or peripheral gas detection equipment in terms of the framework and philosophy of IEC 61508, and introduces the particular requirements demanded by a fixed gas detection system as shown in Figure 2. This international standard does not consider the Safety Integrity Level SIL 4. SIL 4 is assumed to be unrealistic to be achieved for gas detection systems. This international standard is applicable for fixed gas detection systems, which might consist of the following hardware functional units - Gas sensor/transmitter - Gas detection control unit (logic solver) - Gas sampling (single and multiplexed streams) - Gas conditioning - Automatic gas calibration and adjustment - Output module (if not part of the control unit).

Explosive atmospheres -- Part 29-1: Gas detectors - Performance requirements of detectors for flammable gases
EN 60079-29-1:2007

This part of IEC 60079-29 specifies general requirements for construction, testing and performance, and describes the test methods that apply to portable, transportable and fixed apparatus for the detection and measurement of flammable gas or vapour concentrations with air. The apparatus, or parts thereof, are intended for use in potentially explosive atmospheres (see 3.1.8) and in mines susceptible to firedamp. This standard is also applicable when an apparatus manufacturer makes any claims regarding any special features of construction or superior performance that exceed these minimum requirements. In these cases, all such claims should be verified and the test procedures should be extended or supplemented, where necessary, to verify the performance claimed by the manufacturer. When verifying the superior performance of one criterion, other performance criteria are not required to meet the standards minimum requirements, however, these reduced claimed performance criteria (as confirmed in the manufactures Installation Manual) should also be verified. (e.g. temperature range of 0 °C to 60 °C; 0 °C to 40 °C at ±10 % accuracy and 40 °C to 60 °C at ±15 % (manufacturers claimed accuracy). The additional tests should be agreed between the manufacturer and test laboratory and identified and described in the test report. This standard is applicable to flammable gas detection apparatus intended to provide an indication, alarm or other output function; the purpose of which is to give a warning of a potential explosion hazard and in some cases, to initiate automatic or manual protective action(s). This standard is applicable to apparatus, including the integral sampling systems of aspirated apparatus, intended to be used for commercial, industrial and non-residential safety applications. This standard does not apply to external sampling systems, or to apparatus of laboratory or scientific type, or to apparatus used only for process control purposes. It also does not apply to open path (line of sight) area monitors. For apparatus used for sensing the presence of multiple gases, this standard applies only to the detection of flammable gas or vapour. This standard supplements and modifies the general requirements of IEC 60079-0. Where a requirement of this standard conflicts with a requirement of IEC 60079-0, the requirement of IEC 60079-29-1 will take precedence.
