【国外标准】 Standard Specification for Gravity-Convection and Forced-Circulation Water Baths

This specification covers the performance requirements for four types (Types IA, IB, IIA, and IIB) of unloaded and covered general-purpose gravity-convection and forced-circulation water baths ordinarily used in testing operations. The temperature within the bath chamber shall be controllable by an automatic device and, when examined by appropriate test methods, shall be uniform within the tolerances as to uniformity and time constant specified for the particular type of bath.1.1 This specification covers the performance requirements for general-purpose water baths ordinarily used in testing operations. It is applicable to gravity-convection and forced-circulation water baths operating in the range from 5 °C above ambient to 100 °C and having a water volume up to 100 L.1.2 This specification covers unloaded, covered water baths.1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
