From Kishore Kumar K R of Nukote on October 23, 2013:
Trust your supplier. Conduct a thorough vendor qualification in the first place and FR-IR on every batch if features and properties are critical, or conduct these tests at random or periodically. COA/Batch certificate is a document you should have with every single batch.

From Aldrin Cordovez of Kuwait Oil Company on October 6, 2013:
The most effective way to assure the consistency of supplied coatings is by the use of FR-IR fingerprinting (ASTM D7588) of liquid paint in each batch of paint delivered.

From Frank Rea of GPI-Southeast on September 18, 2013:
In addition to a certificate of compliance or analysis, a few rather simple tests, performed by the purchaser's or a third-party laboratory, should be used as a screening tool. These tests may include density (wt/gal), % solids, viscosity, and color (if necessary). Any anomalies in the results from these tests would lead to further testing such as infrared spectroscopy.

From David Cerchie of Versaflex Inc. on September 18, 2013:
Another criteria would be to specify that the coatings manufacturer be currently certified as an ISO 9001:2008 Quality Manufacturer. Maintaining such quality standards is a further indication that consistency in products is part of the company objectives.

From trevor neale of TF Warren Group on September 16, 2013:
A simple way is to include in the PO a requirement for a signed certificate of compliance to the published technical specification for each batch. Include color if important. It will then be necessary for the issuer of the PO to verify that such certs are in compliance before committing the coating to production. Depending on the liabilities involved, there are many ways to insure even more stringent conformance to ensure the product matches the original samples upon which the buying or selection was based.
