The National Members are crystallographic associations of countries or regions which have been accepted by the Council and have paid their current subscription; the National Members have the right of representation and voting in the Council via an appointed delegate.
The Adhering Body is normally the National Crystallographic Association. If such an association does not exist, a body may be approved by the Council to represent the practising crystallographers of that country.
Countries which are not part of Europe geographically may be admitted at the discretion of the Council.
Any number of countries may agree to form a group in order to name or establish a single Adhering Body. This body shall form a joint national or regional committee for crystallography.
If you are interested in join the ECA as a National Member, please contact the ECA NM Officer. Find general instructions for becoming a National Member of the European Crystallographic Association on this link.
