It shows the cleanness of oil as available minimum particle /100 ml oil sample. size of 5 to 10 micron particle is commended as less as possible. We are using fuel in aeroplane jet engine under 5-10 micron particle available 2 or less means fuel has cleanliness class NAS 2 or less. National Aerospace Standard (NAS)

Nas, no contest.
Neither, Nas is in the 5% Nation.
NAS is Network Attached Storage, Look on Wikipedia for more.there's also a New York rapper "Nasir Jones" a.k.a. NaS.
The NAS value of hydraulic oil is in reference to the contamination level of the hydraulic oil. The NAS value is a standard within the aerospace industry.
The value of Gas Turbine Oil should be 6.
NAS value is a standard adopted worldwide to grade the oil contamination, based on particle size. The standard tells how many particles of a particular size are present in that sample. Higher the NAS value higher is the contamination (bigger particles). Hence the delicate sophisticated type of application like control valves allow oil of NAS value of 5 - 6.
5
6~7
ANS is 6 to 7
Please rephrase your question as it makes absolutely no sense.
Well, it depends on the lube oil you use. The basics for determination is usually common sense, to be honest. It will also depend on how big the boiler feed pumps are too.
