Hi,
1.Did anybody tell me what is the main difference between NAS Class & SAE AS 4059?.
2.If I use Automatic particle counter(APC) to measure particle as per SAE AS4059D Class6B-F.Is there is any specific calibration I have to go.Bcoz I was in the impression I have to calibrate APC as per ISO 11171 bcoz I have APC calibrated as per ISO 4406.
Anybody,pls clarify my questions-
