ASTM 2170-11

[rapidrhrep]

Keep in mind the what the changes to the ASTM standard are:

1) All products have to have edundancy rings at the bottom to isolate air space (Rapid RH has always had)
2) All products have to have their sensor's isolated, below the redundancy rings, to alleviate any infiltration of ambient air. (Rapid RH has always had)

Then while we are on the subject of trying to make pertinent specifications of manufaturer's products standardized, lets have sleeves go all the way to the top. Does that make a difference, no evidence it does, but now everyone is "equal". Think about how much the Rapid RH has to change vs the other products??
