Question: In § 4 of IEC 61048 and in § 3 of IEC 61049 rules for sampling plan are provided.& z* W( x, Q7 ?4 X/ ~$ U
Beside the main rule, the following additional statement is given: “The capacitor with

, e* I! G. S- L/ R: K- [exceeds that of the maximum capacitance value in the range by 10% or greater.- E" S$ u) ~, ]1 K8 h$ b
Similarly, the capacitor with the minimum capacitance per unit area shall also be

/ A% [  S2 @, J; N+ Z+ {10% or greater”. Nevertheless, the sampling plan is not well specified when the  m# M8 o$ L% z8 P
above case occurs. How should be composed the final sampling for tests?/ Z" ?- z4 C% G% X. h3 W0 z
Decision: For the time being to apply the following proposed solution:
