ASTM E210
1. Scope
1.1 This standard covers the screw thread used for mounting the objective assembly to the body or lens turret of microscopes. It is based on, and intended to be interchangeable with, the screw thread introduced and adopted many years ago by the Royal Microscopical Society of Great Britain, generally known as the 'RMS thread' and now almost universally accepted as the basic standard for microscope objective mountings. Formal recognition, however, has been extremely limited.
