(IEC 60079-0:2004) EN ISO 8031, Rubber and plastics hoses and hose assemblies — Determination of electrical resistance (ISO 8031:1993) 3 Terms, definitions and pictograms For the purposes of this European Standard, the terms, definitions and pictograms given in EN 132:1998, EN 134:1998 and the following apply. 3.1 compressed air line breathing apparatus with a demand valve for use with a full face mask apparatus, which is not self-contained, in which the wearer is supplied with breathable air from a source of compressed air at a maximum pressure of 10 bar 3.2 facepiece full face mask conforming to EN 136 (Class 2 or Class 3) 3.3 mobile high pressure air supply system supply system that may include a compressor, filters, compressed air pressure vessels, for use as a mobile source of breathing air 3.4 switch over device device that ensures that in the event of a malfunction or disconnection of the airline, the air supply, when airline is used in conjunction with self contained breathing apparatus, automatically switches over to the self contained air supply, without interruption of supplied air to the wearer 4 Description This apparatus, with or without positive pressure, enables the wearer to be provided with breathable air, which shall be in accordance with EN 12021, which, on inhalation, flows through a lung governed demand valve operating at negative pressure (apparatus without positive pressure), or at positive pressure (apparatus with positive pressure) to a suitable facepiece, possibly via a breathing hose. A compressed air supply tube connects the wearer to a supply of compressed air. Exhaled air flows into the ambient atmosphere via an exhalation valve. NOTE Conformance to EN 12021 can be ensured by a breathable air supply system or an additional device such as a compressed air filter system.

EN 13274-2:2001. These answers shall be used by the test house to determine if the apparatus passes or fails. The test house shall provide full details of those parts of the practical performance tests which revealed these imperfections. NOTE This will enable other test houses to duplicate the tests and assess the results thereof. The testing shall be done in accordance with 6.4. 5.7 Connections 5.7.1 General Components of the apparatus shall be readily separated for cleaning, examining and testing. All demountable connections shall be readily connected and secured, where possible by hand. Any means of sealing used shall be retained in position when the joints and couplings are disconnected during normal use and maintenance. Testing shall be done in accordance with 6.3 and 6.4. 5.7.2 Couplings The apparatus shall be constructed so that any twisting of the hoses and tubes does not affect the fit or performance of the apparatus, or cause the hoses or tubes to become disconnected. At least one swivelling coupling shall be fitted to the compressed air supply tube adjacent to the wearer. The design of the couplings shall be such as to prevent unintentional interruption of the air supply. Testing shall be done in accordance with 6.3 and 6.4. 5.7.3 Strength of connections to full face mask, demand valve, medium pressure connecting tube and breathing hose Connections of the breathing hose at the full face mask and at the demand valve or between the full face mask connector and the demand valve shall withstand a force of 250 N. Testing shall be done in accordance with 6.5. 5.7.4 Connection between apparatus and full face mask The connection between the breathing apparatus and the full face mask may be achieved by a permanent, special or thread type connector. If a thread connector is used, either it shall conform to the requirements of one of the following standards:  EN 148-1, for breathing apparatus without positive pressure,  EN 148-3, for breathing apparatus with positive pressure

Apparatus without positive pressure shall be provided with a manually operated means of providing a supply of air at a flow rate of at least 60 I/min at the manufacturer's minimum stated compressed air supply conditions. Testing shall be done in accordance with 6.3, 6.4 and 6.15.3. NOTE Apparatus with positive pressure may also be provided with such a device.
