Introduction

JJF 1071-2010 "Rules for Writing National Measurement Calibration Specifications", JJF 1059:1-2012 "Measurement Uncertainty Assessment and Expression" together constitute the basic series of standards that support the formulation and revision of this standard: This specification replaces JJF 1030-2010 "Technical Performance Test Specification for Constant Temperature Baths": Compared with JJF 1030-2010, in addition to editorial modifications, the main technical changes in this specification are as follows: ---According to the current temperature measurement regulations and specification requirements, add -80℃~300℃ to the range; ---According to the current temperature measurement regulations and specification requirements, increase the technical performance indicators of the constant temperature bath; ---Add the term "immersion depth"; ---Based on the technical index requirements of the constant temperature bath, it is clear that the minimum immersion depth of the standard platinum resistance thermometer is 100mm; ---Add test items for temperature rise and cooling rate deviation of constant temperature bath: The previous releases of this specification are as follows: ---JJF 1030-2010; ---JJF 1030-1998: Thermostatic bath for temperature calibration Technical Performance Test Specifications
