13 Sensor verification
A company maintaining quality system according to ISO 9000 quality standards
must have defined procedures for controlling and calibrating its measuring equip-
ment. Such procedures are needed to demonstrate the conformance of the final
product to specified requirements. The company should
− Identify the required accuracy and select appropriate equipment for measure-
ments.
− Establish calibration procedures including a check method and acceptance cri-
teria.
− calibrate the equipment at prescribed intervals against certified equipment
having a known valid relationship to nationally recognized standards. In cases
where no such standards exist, the basis used for calibration must be docu-
mented.
K-Patents verifies the calibration of all delivered instruments according to a pro-
cedure similar to the one described Section 13.1. K-Patents quality system is
ISO 9001 certified by Det Norske Veritas.
