CALIBTATION OF THE ANALYTICAL INSTRUMENTS

1 INTRODUCTION

1.1 Each analyser used for the measurement of an engine's parameters shall be calibrated as necessary in accordance with the requirements of this appendix.

2.2 Except as otherwise specified, all results of measurements, test data or calculations required by this appendix shall be recorded inthe engines's test report in accordance with section 5.10 of this Code.

1.3 Accuracy of analytical instruments

1.3.1 Permissible deviation of instruments shall be traceable to national (international) standards and shall comply with the requirements as set out in tables 1 and 2.
