Formerly under the jurisdiction of Committee E41 on Laboratory Apparatus, this specification was withdrawn in January 2022. This standard is being withdrawn without replacement due to its limited use by industry.
РефератThis specification covers the basic and design forms, lead, classification, and nominal size of 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.

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.
1.2 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.
