4.17 Tearability. The tape shall be designated as ʺtearable by handʺ if its tensile strength (see 4.4) does not
exceed 90 N/cm, and the tape after manual tearing has an even edge without fraying.
4.18 Hot-water Jet Test (Exterior Tape Only) .Adhesive tapes used in wet zones shall withstand loads as they
may occur in cleaning operations with hot water devices.
