Thermometers, Direct Reading and Remote Reading
|Publication Date:||13 April 2001|
ASME B40 Standard Committee is comprised of a balanced cross-section of manufacturers of pressure and temperature instruments, users, and interested individuals representing government agencies, testing laboratories, and other standards producing bodies.
This Standard has been prepared not only to provide performance, configuration, and interchangeability guidelines, but also to inform and update the specifier and user, regarding product types, application, and use. The Standard is a vehicle by which the Committee can transmit to users the benefits of their combined knowledge and experience regarding the proper and safe use of temperature instruments and accessories.
Use of this advisory standard is a voluntary matter and shall in no way preclude the manufacture or use of products that do not conform. Neither ASME nor the B40 Committee assumes responsibility for the effect of observance or nonobservance of recommendations made herein.
This document supersedes SAMA Standard RC-6-10-1963, RC-4-1-1962, and is intended to supersede Military Specifications MIL-I-17244, MIL-T-19646, and MIL-T-24272.
Suggestions for the improvement of this Standard are welcome. They should be addressed to The American Society of Mechanical Engineers, Secretary, B40 Main Committee, Three Park Avenue, New York, NY 10016-5990.
