IEC 60454-3-4:2007 contains the requirements for pressure-sensitive adhesive tapes made with cellulose paper, creped and non-creped, with rubber thermosetting adhesive. Materials, which conform to this specification, meet established levels of performance. However, the selection of a material by a user for a specific application should be based on the actual requirements necessary for adequate performance in that application, and not based on this specification alone. This third edition of IEC 60454-3-4 replaces the second edition, published in 1998, as well as IEC 60454-3-5, published in 1998. It constitutes a technical revision. The main changes with regard to the second edition is the consolidation of this part with IEC 60454-3-5. All requirements were confirmed. IEC 60454-3-5 is to be withdrawn at the time of this publication. Keywords: pressure-sensitive adhesive tapes made with cellulose paper, creped and non-creped, with rubber thermosetting adhesive
