P-members are kindly invited to nominate experts to JWG 25, and the appointed experts should be entered
into the IEC Expert Management System (see documents AC/21/2004 and AC/24/2008) by 2019-10-11.

IEC national committees are invited to consult both IEC TC 88 and IEC TC 57 delegates when developing
their national positions. Work on the Condition Monitoring update will be initiated in a one-day workshop in
