It was agreed that although manufacturer 's declaration may well be taken into consideration,3 f+ i6 w" n I9 b* D+ Z% f$ n
however testing must be performed to ensure that requirements of IEC61010-1 is met.% M, Y7 \8 K! q7 Z
Explanatory Notes: [9 o- l) [% \: n- }5 A: F, T
In IEC61010-1, there is no requirement to simulate the ageing process of critical components

It should be noted that after each single fault condition test, where necessary, the required

Note that under compliance criteria there is no reference to 'Declaration by manufacturer'.
