I am curious, why is brightness important? The most significant index is hardness and there are testing techniques that have been accepted by the industry for many years.
Best regards

Subject: [TN] Criteria for brightness of Hard Gold plating
Hi Technetters
We did discussion for brightness of Hard gold plating surface with customer They have machine to check the brightness of Gold plating surface..
They're just curious for definition of brightness of hard gold plating.
How can we determine the level of brightness for gold plating status such as bright hard gold, semi bright? Is there any number or judgement to determine level of brightness?
Your wisdom will help a lot. THanks
