What is BS EN 50104-Electrical equipment for detection of oxygen about?
BS EN 50104 is a European Standard that discusses gas detectors.
BS EN 50104 specifies general requirements for design, testing, and performance, and describes the test methods that apply to portable, transportable, and fixed equipment for the measurement of the oxygen concentration in gas mixtures indicating up to 25 % (v/v). The equipment, or parts thereof, may be intended for use in explosive atmospheres (see 4.1) and in mines susceptible to firedamp.
BS EN 50104 applies to equipment with an oxygen measuring function for explosion protection in the case of monitoring inertisation.
Commonly used oxygen sensors in commercial equipment for industrial application are:
- Electrochemical sensors (aqueous and solid electrolytes)
- Paramagnetic sensors
- Zirconium dioxide sensors
- Tunable diode laser absorption spectroscopy sensors
BS EN 50104 is applicable to equipment 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 an alarm setpoint.
Note: BS EN 50104 does not apply to external sampling systems, or to equipment of laboratory or scientific type, or to medical equipment, or to equipment used only for process monitoring and/or control purposes. For equipment used for sensing the presence of multiple gases, this BS EN 50104 applies only to the measurement of oxygen.
Who is BS EN 50104- Electrical equipment for detection of oxygen for?
BS EN 50104 on detection and measurement of oxygen are relevant to:
- Manufacturers of gas detection equipment
- Manufacturers of alarms and warning systems
- Manufacturers of sensors
- Quality control and safety personnel
- Mining industry
Why should you use BS EN 50104- Electrical equipment for detection of oxygen?
BS EN 50104 applies to equipment intended for monitoring oxygen deficiency and enrichment. It is applicable to equipment, including integral sampling systems of aspirated equipment, intended to be used for commercial, industrial and non-residential safety applications.
The test methods and procedures described are intended as a basis for establishing whether the equipment conforms to the performance requirements given in BS EN 50104.
BS EN 50104 provides you with best industry guidance on design considerations for indicating devices, alarm signals, fault signals, adjustment functions, gas detection transmitter and gas detection control units. Compliance with these requirements and test methods can ensure timely and efficient mitigation of potential hazards. Moreover, dangerous situations arising from incidents of delayed response, false alarm and improper functioning of fault signals can be prevented with optimal functioning of oxygen-detecting equipment.
