Dr Dümmler informed that the Japanese ISO delegation asked whether the reference values can be reproduced over the years. As an answer, the German delegation undertook a round robin with 3 companies. Japan was keen that an alternative supplier (alternative to Eurogard) could be available and their products be used.

Intermediate results of the German ound robin campaign:

• Depends on the size of the equipment
• Similar coating machines commercially available can produce reproducible results.
