ISO 9117-9

Introducing ISO 9117-9- Industrial Physics

ISO 9117-9 is part of an international ISO testing standard to determine the surface-drying characteristics of a coating of a paint or varnish which dries by the action of air, or by chemical reaction of its components. 

The International Organization of Standards (ISO) produces a wide range of ISO standards to guide manufacturers, production lines and laboratories when checking the integrity of packaging, products, and materials across many industries.  

ISO 9117 surface drying testing terms and definitions

The ISO 9117 coating surface drying testing standard includes a number of commonly used terms and definitions to familiarize with:  

• Surface-drying state: condition of a surface of a coating of paint or varnish determining whether it is dry or not
• Surface-dry: state of a coating of paint or varnish when ballotini can be lightly brushed away without damaging the surface of the coating
• Surface-drying time: period of time between the application of a coating of paint or varnish to a prepared test panel and the assessment of the coating as just surface-dry by the test procedure specified.

Additional parts of the ISO 9117 coating testing standard

There are several additional parts to the ISO 9117 coating testing standard, including: 

• ISO 9117-1 – determination of through-dry state and through-dry time 
• ISO 9117-2 – pressure test for stackability 
• ISO 9117-4 – test using a mechanical recorder 
• ISO 9117-5 – modified Bandow-Wolff test 
• ISO 9117-6 – print-free test.
