The latter can operate at negative pressure or at positive pressure and is connected to a suitable full face mask, 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.

EN 14593-1:2018 (E) 8 4 Requirements 4.1 General All test samples specified in the related test clauses shall meet the relevant requirements. Where it is required in a specific clause, the manufacturer shall declare that a risk assessment e.g. a Failure Modes and Effect Analysis (FMEA) concerning these specific requirements has been conducted. NOTE Further information is given in EN 60812 [3]. If the manufacturer claims that the RPD may be used in potentially explosive atmospheres it shall comply with the appropriate requirements. 4.2 Nominal values and tolerances Unless otherwise specified, the values stated in this document are expressed as nominal values. Except for temperature limits, values which are not stated as maxima or minima shall be subject to a tolerance of ± 5 %. Unless otherwise specified, the ambient conditions for testing shall be between 16 °C and 32 °C and (50 ± 30) % relative humidity. Any temperature limits specified shall be subject to an accuracy of ± 1°C. 4.3 Ergonomics The requirements of this document are intended to take account of the interaction between the wearer, the RPD, and where possible the working environment in which the RPD is likely to be used. The RPD shall satisfy 4.4 and 4.8 . Testing shall be performed accordance with 5.3. 4.4 Materials 4.4.1 All materials used in the construction shall have adequate resistance to deterioration by heat and adequate mechanical strength. After any pre-conditioning according to 5.7, testing shall be performed in accordance with 5.3. The manufacturer shall supply a declaration that this was addressed by a risk assessment, e.g. a FMEA. Check in accordance with 5.2. 4.4.2 If the manufacturer claims that the RPD may be used in potentially explosive atmospheres, exposed parts, i.e. those which can be subjected to impact during use of the RPD shall not be made of aluminium, magnesium, titanium or their alloys. The manufacturer shall supply a declaration that this was addressed by a risk assessment, e.g. a FMEA. Check in accordance with 5.2. 4.4.3 Materials that can come into direct contact with the wearer's skin or that can affect the quality of the breathed air shall not be known to be likely to cause skin irritation or any other adverse effects to health.

EN 14593-1:2018 (E) 9 4.5 Practical performance The complete RPD shall undergo practical performance tests under realistic conditions. These general tests serve the purpose of checking the RPD for imperfections that cannot be determined by the tests specified elsewhere in this document. If during any activity, by any test subject, the test subject fails to finalise the selected activity due to the RPD being not fit for the purpose for which it has been designed, the RPD shall be deemed to have failed. After completion of the activities the test subjects are asked to answer the questions in EN 13274-2:2001, 6.6. Testing shall be performed in accordance with 5.3. 4.6 Connections 4.6.1 General Components of the RPD 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. Check in accordance with 5.2 and test in accordance with 5.3. 4.6.2 Couplings The RPD shall be constructed so that any twisting of the hoses and tubes does not affect the fit or performance of the RPD, 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. Check in accordance with 5.2 and test in accordance with 5.3. 4.6.3 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 performed in accordance with 5.4. 4.6.4 Connection between RPD and full face mask The connection between the RPD and the full face mask can 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 RPD without positive pressure, — EN 148-3, for RPD with posit
