Definition - What does Coating Specification mean?
A coating specification is a document that is used to govern how a coating is made and what materials are in the coating's composition. A coating specification is intended to remove any miscommunication between what the purchaser believes it is buying and what the seller believes it needs to sell.
Corrosionpedia explains Coating Specification
A coating specification is made with the intention of eliminating uncertainty in regards to the composition of a coating material. A coating specification is also made so that different suppliers know how to formulate a coating that conforms to the requirements. The specification therefore allows consumers and suppliers to know about the product with which they are engaged in business.
Coating specifications are generally created by a third party so that neither the seller nor the purchaser can be dishonest with one another. Furthermore, a third party allows proprietary coatings to be grouped into a bucket with other proprietary coatings from other companies. This eliminates confusion for the customer.
Third party organizations that are involved in coating specifications include the National Association of Corrosion Engineers (NACE) and the American Society for Testing and Materials (ASTM).
