Hi, Mac,
I responded to your "virus" thread, but hit delete before posting! By accident, and really could'nt face re-typing another detailed post, sorry!
The recent ATP test that you have gone through is gaining some momentum in the industry, as its a very precise measurment, and does not rely on a subjective measurement from any assessor.
Bics, and others have tried to inform the industry of acceptable standards in the past,but the ATP tests is probably about the best at the moment, with the provisio, that any surface tested should be free fom visible debris and cleaning marks (smears etc).
Regards,
Rob
