Leland,
I would not use that number with any confidence. The standard is not
written for mortar and the reported precision and bias may not apply. To my
knowledge, there has been no interlaboratory testing using E 96 for mortar
or brick.

Mike,
Is it true that ASTM E-96 allows for a 76% acceptable variance for testing
moisture vapor transmission?
Best,
Leland
