This Standard is confined to analog, liquid-in-glass Industrial type thermometers for Industrial Applications that sensc process temperature by means of the expan- sion of the liquid within the glass thermometer bulb. The liquid fll, based on the temperature to be measured, may be mercury or organic liquid. This Standard does not include laboratory type ASTM thermometers (Speci- fication Designation: ASTM E 1-86). NOTE: Thermowell Siandard ASME B40.9 docs not include dimen- sional information or drawings for the intemally lapered thermowell described in this Standard. This intemally tuapered thermnowell has been in continuous use since 1927. The dimensional information listed is to be considered critical to insure interchangeability within the industry, for both new and existing thermometers. 2 HISTORY Since 1900 the introduction of the liquid-in-glass thermometer for pipe line, tankage, and other tempera- ture measuring applications became a reality. In such equipment, if the ftting attaching the thermometer to the equipment is not dimensionally standardized, extreme dificulty in replacing a thermometer is encountered. Over the years manufacturers have standardized the product. To accommodate the interchangeability, this endeavor has been helped by the introduction of Mili- tary, Federal, and Trade Association Standards. Dimen- sional and other information from the followving Liquid- in-Glass Industrial Thermometer specifcations have been incorporated into this publication. (a) F.S.B.

OF THE ABOVE STANDARDS HAVE BEEN CANCELLED. THIS STANDARD RETAINS THE CRITICAL DIMENSIONS AND TERMINOLOGY OF THE CANCELLED STANDARDS. ASME has been granted authorization by SAMA to assume responsibility for the cancelled RC7-1 Standard, and replace it with this B40.8 Standard. 3 STYLE 3.1 Industrial The thermometers described have a nominal case size of 7 in., 9 in., or 12 in. See Fig. 4B. 3.2 Compact 6 in. The thermormeters described are of a different dcsign and are not interchangeable with Industrial Style of para.3.1. The primary use for 6 in. nominal case size thermometer is for small diameter pipe lines, wherein shorter immersion length of thermowells is required, or mounting space for the thermometer is restricted.ASME B40.200 pdf download.
