The definition of the coating is the final part of the “Process Painting” where as a result of the above analysis, all the requirements of the specifications, geometry and specifications of the product, the products used, where all the technical information to define the mode of application of the coating and methods of tests and inspections to verify the result.

The definition of the painting process involves many functions of the company, starting from the technical service quality, production and safety in the service of your service provider, if the activity is carried out in application outsourcing.

The painting is usually played in a technical document which will be annexed to the specification or other documents such as the technical and security of the coating.

The document “painting cycle” normally contains:

The scope and applicability of the same;

The normative references applicable in the various stages of the process:

Normally shows the standards mentioned in the contract. These normally cover both the characteristics of the product of the process is that of the methods of control and test to be used.

Brief description of the artefacts object of the coating system;

Normally we report the descriptions of artifacts.
