Vat Thermometer Calibration Check Sample Clauses

Vat Thermometer Calibration Check. Twice a year, the milk haulage contractors compare the farm vat temperature gauge / digital readout with a calibrated hand-held thermometer. Norco Milk Supply issues a letter to each Supplier advising of the vat(s) thermometer and the standard thermometer reading(s). Where the difference in thermometer readings is more than +/- 1.0°C, the Supplier must take action to rectify. Checks will follow until the discrepancy is recorded at less than +/- 1.0°C. If the thermometer on the vat cannot be adjusted, the Supplier must notify Norco Milk Supply and attach a notice to the vat beside the gauge / digital readout showing how much the reading is out by. It is a quality assurance requirement that at least once per year Suppliers calibrate their hand-held food grade thermometers using the “ice water” method. CHAPTER BULK MILK COLLECTION
