ANNEX V U.K. GENERAL HYGIENE REQUIREMENTS FOR THE PROCESSING OF CATEGORY 1, 2 AND 3 MATERIAL

CHAPTER V U.K. Validation procedures

2. In the case of a batch pressure system: U.K.

(a)

the temperature must be monitored with a permanent thermocouple and it must be plotted against real time;

(b)

the pressure stage must be monitored with a permanent pressure gauge. Pressure must be plotted against real time;

(c)

the processing time must be shown by time/temperature and time/pressure diagrams.

At least once a year the thermocouple and the pressure gauge must be calibrated.
