NOTE Further information is given in EN 60812.
If the manufacturer claims that the RPD may be used in potentially explosive atmospheres it shall
comply with the appropriate requirements.
Test in accordance with EN ISO 80079-36:2016, EN ISO 80079-37:2016 or IEC TS 60079-32-1.
If the RPD is intended to provide additional protection, e.g. head protection, eye protection, face
protection, or including protective clothing, it shall additionally comply with the relevant requirements
of the standards covering those related PPE.
Check in accordance with 7.3.
It shall not be possible to connect any part of the RPD to a thread conforming to EN 148-2 or EN 148-3.
Check in accordance with 7.3.
When the RPD manufacturer states that an accessory is intended for use with the RPD, the RPD
including the accessory shall be tested.
Check in accordance with 7.3 and the appropriate test method.
6.2 Nominal values and tolerances
Unless otherwise specified, the values stated in this document are expressed as nominal values. Except
for temperature limits, values which describe test conditions and that 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.
For each of the required measurements performed in accordance with this document, a corresponding
estimate of the uncertainty of measurement should be evaluated. This estimate of uncertainty should be
applied and stated when reporting test results, in order to enable the user of the test report to assess
the reliability of the result.
6.3 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 6.5, 6.11 and 6.12.
