5.1.2 A control shall be provided to adjust the vapour concentration (volume fraction) calibrated for
each intended anaesthetic agent and
a) undernorrnal operating conditions, it shall not be possible to set the control above the calibrated range,
b) the control can have a separate OFF position in addition to a or”zero” posit,on, and
C) a means shall be provided to reduce the nsk of unintended change of the control from its set position. Check compliance by visual inspection and functional testing.
5.1.3 When operated in accordance with the manufacturers instructions, it shall not be possible to overfill the draw-over vaporizer such that
a) its pertormance is allected, or
b) the fluid level is no longervisible orindicated, Check compliance by visual inspection and functional testing.
5.1.4 The draw-over vaporizer shall either
a) be provided with mounting fittings suitable to enable It to be rigidly supported, or
b) have a base designed to provide stability when freestanding.
Check compliance by visual inspection and functional testing.
5.2 Performance
5.2.1 The output In the O”, “OFF”, or”zero” position shall be less than 0,1 %. Check compliance by the test given in 8.2.
5.2.2 • The accuracy of output shall be within ±20 % of set value for concentrations (volume traction) greater than 1 % and ±50 % of set value for concenlrations oil or below under the following conditions.
