7.3.2 Test results on permeable materials will be affected by
the impermeable material used in the test.
7.4 Test three replicate specimens on each sample unless
otherwise noted.
8. Procedure
8.1 Cut the test specimen to the requirements of the test
vessel to ensure a good seal. Place specimen across the opening
of the vessel. Be sure the specimen is not sagging.
8.2 Be sure the specimen remains flat while the edge of the
specimen is being securely clamped into place.
