I've just been reviewing notes I made during our recent external audit. The use of calibration equipment was noted in respect of test charts used to assess the output of devices (we service photocopiers) and multi meters that are used to ensure that remanufactured devices are electrically safe. My initial understanding of this line of audit was related to 7.6 - Control of Monitoring and Measuring Equipment. We maintain the calibration of the multi meters and maintain records in respect of 7.6. However, we had never considered test charts under this requirement. I have since reviewed and re-read the requirements of 7.6 and have started to wonder if we have this all wrong as the requirements refer to "determine the monitoring and measurements to be undertaken and the monitoring and measuring equipment needed to provide evidence of conformity of product to determined requirements"... does this requirement relate to the requirements determined by the customer or all requirements of the product including those not specified by the customer but necessary for the specified or intended used.
