Test equipment and measurement standards should be labeled to indicate the date of last calibration by whom it was calibrated and when the next calibration is due. When the size of the equipment limits the application of labels an identifying code should be applied to reflect the serviceability and due date for the next calibration. This provides a visual indication of the calibration serviceability status. Both the headquarters calibration organization and the instrument user should maintain a two-way check on calibration. A simple means of doing this is to have a small form for each instrument with a calendar of weeks or months depending on the interval required across the top which can be punched and noticed to indicate the calibration due date. Planning and Estimating Planning is the heart of good inspection and preventive maintenance. As described earlier the first thing to establish is what items must be maintained and what the best procedure is for performing that task. Establishing good procedures requires a good deal of time and talent. This can be a good activity for a new graduate engineer perhaps as part of a training process that rotates him or her through various disciplines in a plant or field organization. This experience can be excellent training for a future design engineer. Writing ability is an important qualification along with pragmatic experience in maintenance practices. The language used should be clear and concise using short sentences. Who what when where why and how should be clearly described. The following points should be noted from this typical procedure 1 Every procedure has an identifying number and title 2 The purpose is outlined 3 Tools reference documents and any parts are listed 4 Safety and .
