Instruments calibration

[patsand99]

Maybe somebody knows what is the recommended ambient temperature to perform calibration of pressure instruments , differential pressure transmitters, RTD, thermometers? is there any applicable standards for this?

When calibrating a temperature device your control temperature should compensate or override the ambient effect. For pressure instruments, I would check with the manufacturer, their cells and circuitry are probably slightly different and it would be best to contact them for their recommendation.
Intuitively, I would suggest calibrating them at the same ambient temperature which they operate.
