26 Vibration and noise
Clause 26 of EN 60601-1:1990 + A1:1993 and A12:1993 shall be replaced by the following:
26.101 R The A-weighted sound pressure level caused by the device and to which the patient is exposed shall
be measured under the conditions given in 26.102.
NOTE By the test set-up it should be ensured that the sound presure level measurement of the device is not interfered by
the noise caused by the tubing system and the gas flow leaving the tubing resistance system at the patient connection port.
26.102 Place the device on the floor and fit with the breathing tube as provided or recommended by the
manufacturer. Connect a resistance with 4 mm internal, 40 mm length and outlet angle of 45° to the patient
connection port (see figure 101). Acoustically isolate the tubing system and the gas leaving the resistance at the
patient connection port by a suitable means out of the testing area so that the noise caused by the tubing system
and by the gas flow is not interfering with the sound pressure measurement of the device.
Set the device in order to achieve a continuous pressure of 1 kPa at the patient connection port.
Using a microphone of the sound level meter complying with the requirements of type 1 instruments specified in
IEC 60651:1979, measure the sound pressure levels at 10 positions with equal distances to each other in the area
specified for the patient position in the instructions for use at a distance of 1 meter of the device.
Calculate the average value of the measurements.

Ensure that the A-weighted background level of extraneous noise is at least 10 dB below that measured during the
test.
Take measurements using the frequency-weighting characteristic A and the time-weighting characteristic F on the
sound level meter in a free field over a reflecting plane as specified in ISO 3744.
