Coating gauges and their reference pieces
For a thickness gauge used on painted steel or aluminium, identify the base metal, probe type and coating thicknesses the inspection sheet calls for. List the reference foils and bare reference plates by marking. Ask the inspector which pieces belong to the job and which must stay at the workshop for other gauges.
Match the inspection record to the work package
If the finishing record also calls for relative humidity, give the hygrometer model and the humidity range the contractor records. Identify the person releasing it and when the next coating inspection is due. For work at the cluster, send the named gate and site contact supplied by the package manager.
A supplier in IMT Rohtak may retain its own reference pieces. Put the Rohtak assets on a separate line of the order so its inspector gets the correct results and return case.
Keep reference foils with their own records
A nominal thickness printed on a foil is an identification value. If the inspection method relies on a measured value from a certificate, keep that report with the foil's identifier. List the pieces you want checked and distinguish them from the gauge used to read a coating. Send clear markings or photographs when the original holder no longer identifies each piece.
For environmental readings taken during a coating job, specify whether temperature, relative humidity or both are required from the instrument. Include the sensor arrangement and the conditions used in the inspection procedure. A combined meter may offer additional calculated quantities; mark the particular readings your team needs reviewed instead of assuming every display function is included.
