Hi everybody,

Do you know which standard I must follow to calibrate thermobalances?

Any recommendation to calibrate?

Thanks a lot.

Thanks a lot.
From quality standpoint , first you should evaluation if you can calibrate in house or externally, in a lab with ad hoc accredidation ( for instance ISO 17025). In any case, you should understand if the calibration or not can affect the quality of your product.
If you are capable with competencies. adequate procedures and resources , you can do yourself.
As per ISO 9001 , you shall meet 7.6 clause, if you are ISO TS you shall comply with 7.6.2, 7.6.3.1 and 7.6.3.2.
Hope this helps:bigwave:

Does anyone here by chance have a thermobalance calibration procedure you can share here? Or any related information?

From the link that Marc provided:

Automatic external calibration using either 100 g or 200 g calibration weight (depending on the model) guarantees ongoing accurate results
There is a PDF instruction manual at the same link which gives the recommended calibration instructions.

The primary concern with this device is accurately measuring weight. The drying process (as I can see) appears to be an option. Saying, I'm not sure if I see any quality parameter performed by the drying process; it either works or it doesn't. It works, by drying the material.

Does the thermobalance in question display temperature/relative humidity? That may be another parameter which would need to be verified.

However, after looking around at the material on these devices, they can get quite complex:

So not sure what device you have. A couple of reference suggested the best place to find out is in the instruction manual for the instrument.:)
