SOP for Cyclic Stability Chamber calibration

1.0 OBJECTIVE : To set up procedure for the calibration of Cyclic Temperature Stability Chamber-V (Instrument ID: QC/137).

2.0 SCOPE : This SOP is applicable for calibration of Cyclic Temperature Stability Chamber-V (Instrument ID: QC/137).

3.0 RESPONSIBILITY
3.1 Calibration of Cyclic Temperature Stability Chamber-V will be carried out externally.
3.2 Overall responsibility for implementation and follow-up with the QC Manager or his/her nominee.

4.0 ACCOUNTABILITY
4.1 Head of Quality.

5.0 PRECAUTIONS
5.1 Stability chamber should be calibrated by trained person.
5.2 Calibrated ‘Data Logger’ should be used.

6.0 PROCEDURE
6.1 Calibration of Cyclic Temperature Stability Chamber-V is performed by checking the uniformity of the temperature in the chamber.
6.2 Uniformity of the temperature in the unit is to be checked by using at least 8 point temperature probes indicator for at least 1 hour.
6.3 The temperature mapping is to be done by placing the 8 point temperature probes in different positions in the chamber.
6.4 The permissible limit of temperature is within ± 2°C.
6.5 The calibration may be performed by the Supplier’s certified Engineer of the equipment. In that case the calibration and documentation should be performed as per the protocol of the equipment supplier.
6.6 Frequency of calibration: Yearly ± 10 days.
