5 B! ?1 C' y1 G3 A# e1 OQuestion:
It is not clear at what ambient temperature the limit of 41 °C should be applied. The
% i( n' {8 `7 h( x5 ]. ]7 V) |temperature range of 10 °C to 40 °C stated in Sub-clause 10.2 applies to Table Xa and would
; l( P4 a6 \& \, V) _& F; |+ `appear to apply in this instance. Is a 1 °C temperature difference correct or realistic?
Decision:
( J2 ]" Y7 \& K( r6 mWhen not otherwise specified by the manufacturer, the limit of 41 °C at an ambient

CONDITION except were there is a medical justification for a higher limit/temperature rise.
This requirement should be addressed in Particular Standards.
