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:
