Checklist: quality control of layer thickness and adhesion
The measurements you take before you deliver the task
Use this checklist each time a task approaches delivery. It gathers the inspections that show whether the coating meets the agreed requirement.
§Before measurement
- 01Is the coating cured/dry enough that measurement gives a representative result?
- 02Is the measuring equipment calibrated?
- 03Do you know the agreed requirement for layer thickness and adhesion for this specific task?
§Layer thickness (DFT)
- 01Have measurements been taken at several places on each surface, not just one place?
- 02Have minimum, maximum and average been noted?
- 03Has the result been approved before series production really gets going?
§Adhesion (cross-section)
- 01Has a cross-section test been performed on a test piece or less visible location?
- 02Has the result been assessed against the acceptance limits in the maintenance manual?
- 03Has the test been repeated if the result was in doubt?
§Handover
- 01Are all dimensions checked against the original measurement or size table?
- 02Have any certificates or batch numbers been collected?
- 03Has the customer been informed of the inspection result?
When all points are checked off the task is ready for handover with documentation that stands up.
