A new ASTM (American Society for Testing and Materials) International standard has been approved that covers the more precise ruggedized optical interference (ROI) based coating thickness measurement technology incorporated into all SpecMetrix measurement solutions being supplied globally by Sensory Analytics. ASTM D8331 establishes performance requirements and test methods for the measurement of film thickness of applied coatings by non-destructive and non-hazardous means using ROI technologies. 

The new standard is significant since the correct amount of applied coating thickness plays a critical role in the performance of the final product including its physical, chemical, and long-term durability properties. 

The precise measurement of coating thickness is key to applying the correct amount of each coated layer. 

Non-destructive thickness measurement tests using ROI technology generate immediate coating thickness data that has proven to be highly repeatable and reproducible from one SpecMetrix system to another. 

The test method covers the use of these advanced systems for both in-process and off-line coil coating thickness measurement and coating process control applications.

ASTM and its International standards serve many industries and are recognized globally as the leading developer of voluntary consensus technical standards. 

Companies and consumers can have confidence in the products they buy or use when the systems or services adhere to ASTM standards since they know these purchases are proven to be reliable. ASTM standards enhance product performance by making sure products are long-lasting, high quality, safe for use, and perform as expected.
