The principles currently followed by the bureau and the CIPM in making elections are as follows:
- Persons proposed for election are always of a high scientific standing and have experience which qualifies them to take part in the work of the CIPM.
- In accordance with the discussion at the 17th CGPM, the CIPM should in general take all possible steps to assure itself that each of its members is acceptable to his/her government at the time of provisional election. The bureau encourages the members of the CIPM to continue to maintain this relationship throughout their membership of the CIPM.
- Care is taken to ensure an appropriate spread of scientific disciplines.
- Members should be prepared to make a significant contribution of time and effort to the work of the Metre Convention.
- Efforts are made to maintain a reasonable balance between regions and also to ensure the presence of a small number of members from those States paying the minimum contribution.
- Candidates from Member States three of more years in arrears with their payments to the BIPM are not considered for election.
- One member of the CIPM is always of French nationality. This recognizes the role of France as the originator of the metric system and the depository of the Metre Convention.
- One member comes from each State paying the maximum contribution.
- Particular consideration is given to candidates from States which pay a contribution of 2 % or above.
