5.1 The design of a controlled temperature bath will determine what thermometers can be calibrated and to what extent an isothermal condition is achieved. The lack of thermal stability and... View More
scope:
1.1 This guide is intended for use with controlled temperature comparison baths that contain test fluids and operate within the temperature range of -100°C to 550°C.
1.2 This guide describes the essential features of controlled temperature fluid baths used for the purpose of thermometer calibration by the comparison method.
1.3 This guide does not address the details on the design and construction of controlled-temperatu
1.4 This guide describes a method to define the working space of a bath and evaluate the temperature variations within this space. Ideally, the working space will be as close as possible to isothermal.
1.5 This guide does not address fixed point baths, ice point baths or vapor baths.
1.6 This guide does not address fluidized powder baths.
1.7 This guide does not address baths that are programmed to change temperature.
1.8 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.9 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
