Scope

This Standard specifies test principle, instruments and equipment, preparation
of test piece, test steps and result calculation for water penetration rate of
pressure-sensitive tape.
This Standard includes test methods for water penetration rate on vertical
direction and on cross section direction of pressure-sensitive tape. The test
method for water penetration rate on vertical direction of pressure-sensitive
tape is applicable to single-sided or double-sided pressure-sensitive tape. The
test method for water penetration rate on cross section direction of pressure-
sensitive tape is applicable to double-sided pressure-sensitive tape.
