Calibration and Verification of Temperature Recorders and Thermometers BS EN 12830 and BS EN 13486


Recording of temperatures throughout the cold chain is a regulatory requirement for many transported products for example QFF frozen foodstuffs.

Recent revision to ATP requires temperature recorders to be tested to EN12830 and for periodic verification EN 13486.

In the UK and Eire CRT is the designated test station approved by the Department for Transport, for certifying equipment in accordance to ATP and can therefore certify such equipment acceptable to all ATP contracting parties.
Requirements of EN 12830 1999:

The recorder shall be subjected to the tests listed in Table 4 of EN12830, reproduced below.
Table 4 - Tests and Applications
Tests  Storage  Transport  Subclause 
Determination of temperature measurement error + + 5.3
Determination of response time + + 5.4
Determination of time recording error + + 5.5
Variation in supply, voltage * + + 5.6.2

* if applicable

Requirements of EN 13486

Acceptance comprises comparing the results of measurements and calculating errors to verify that compliance to the relevant specification of limit of permissible errors ( at least class2 of EN 12830 and En 13484).
