Dear Reader

Can anyone explain that the change of electrode clasification under same SFA e.g. change of
electrode from E7018 to E7018-1 or VICE VERSA requires qualification of
new PQR .

Best regards

It is a supplementary essential variable
If there is no low temperature service (No KVc) requalification is not required from E7018 to E7018-1 or VICE VERSA
In low temperature service E7018 qualifies also for to E7018-1 but not VICE VERSA
