What is limit of 5 micron particle size in iso class 5 as per updated iso guideline (2015)
2nd is ISo 2015 first is 1999.Amendments are made in 1999
What is meaning of d,e,f in table for iso class 5
unalbe to find.if you know kindly let me know
d=Sampling and statistical limitations for particles in low concentrations make classification inappropriate.
e =Sample collection limitations for both particles in low concentrations and sizes greater than 1 μm make classification
at this particle size inappropriate, due to potential particle losses in the sampling system.
f =In order to specify this particle size in association with ISO Class 5, the macroparticle descriptor M may be adapted and
used in conjunction with at least one other particle size.
great job to find this
