Ordinary Members can serve as Officers if duly elected, or serve in any capacity in the Society if requested. They shall receive all bulletins, announcements and information of the Society. 

With due consideration of the demand for professional quality there should be an international as well as a national spread of Ordinary Members in order that as many countries and as many institutions and laboratories as possible can benefit from the activities of the Society.

Except in case of resignation, Emeritus Membership is for life. 

Emeritus Members have the right to attend the meetings of the Society and they have all other rights enjoyed by Ordinary Members, but they may not serve as Officers. 

Emeritus Members will receive the minutes of the Business Meetings, which they may attend if they wish, but they will not be eligible to vote.
