Special requirements for construction, test and marking of electrical apparatus of equipment group II, Category 1 G

Special requirements for construction, test and marking of electrical apparatus of equipment group II, Category 1 G

This European Standard specifies the particular requirements for construction, testing and marking of electrical apparatus of equipment group II, conformity Category 1 G as defined in EN 50014:1997. Such apparatus comprises equipment designed to be capable of functioning in conformity with the operational parameters established by the manufacturer and ensuring a very high level of protection. Category 1 G apparatus is intended for use in hazardous areas, in which potentially explosive atmospheres caused by mixtures of air and gases, vapours or mists under normal atmospheric conditions (temperature = -20 °C to +60 °C, pressure = 0,8 bar to 1,1 bar) are present continuously, for long periods or frequently. This standard also applies to apparatus mounted across the boundary between hazardous and less hazardous areas where Category 1 and Category 2 equipment may normally be installed, respectively, for example in the wall of a storage vessel. This standard also makes provision for apparatus installed outside the hazardous area, but electrically connected to apparatus of Category 1 within the hazardous area (associated apparatus).This standard supplements the requirements of EN 50014 to EN 50020 and EN 50028 to adapt the level of safety provided by those standards to the very high level of risk. NOTE: In designing apparatus for operation in a potentially explosive atmosphere under conditions other than the atmospheric conditions given above, this standard may be used as a guide. However, additional testing is recommended related specifically to the intended conditions of use. This is particularly important when the types of protection Flameproof enclosure (EN 50018) and Intrinsic safety (EN 50020) are applied

Explosive atmospheres - Part 17: Electrical installations inspection and maintenance
SIST EN IEC 60079-17:2024

This part of the IEC 60079 series applies to users and covers only those factors directly related to the inspection and maintenance of electrical installations specifically designed for hazardous areas, where the hazard may be caused by explosive gas or explosive dust atmospheres. It does not include: - other fundamental installation and inspection requirements for electrical installations; - the verification of electrical equipment; - protection or ventilation of rooms; - gas detection systems; - the repair and overhaul of explosion protected equipment (see IEC 60079-19). While this standard does not include inspection of safety devices such as used in ventilated rooms (see 60079-13), this standard does include the requirements for inspection and maintenance of individual items of equipment that will be part of such systems, for example motors or sensors. This standard supplements the requirements for inspection and testing in non-hazardous areas in IEC 60364-6. NOTE 1 Standards applied at the date of installation might not have been IEC standards. This standard is intended to be applied where there can be a risk due to the presence of explosive gas or dust mixtures with air or combustible dust layers under normal atmospheric conditions. It does not apply to: - underground mining areas, - dusts of explosives, - pyrophoric substances.

Workplace atmospheres - Part 1: Gas detectors - Performance requirements of detectors for toxic gases
SIST EN IEC 62990-1:2023/A11:2023

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.
