18、rnational Standard is one of a series, which deals with pressure-sensitive adhesive tapes, intended primarily for electrical purposes. This series consists of three parts: Part 1: General requirements (IEC 60454-1). Part 2: Methods of test (IEC 60454-2). Part 3: Specifications for individual materia
19、ls (IEC 60454-3). This standard contains one of the sheets comprising Part 3 as follows: Sheet 4: Cellulose paper, creped and non-creped, with rubber thermosetting adhesive SAFETY WARNING It is the responsibility of the user of the methods contained or referred to in this standard to ensure that the
20、y are used in a safe manner. EN 60454-3-4:2007 4 PRESSURE-SENSITIVE ADHESIVE TAPES FOR ELECTRICAL PURPOSES Part 3: Specifications for individual materials Sheet 4: Cellulose paper, creped and non-creped, with rubber thermosetting adhesive 1 Scope This sheet of IEC 60454-3 contains the requirements f
21、or 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
22、 on the actual requirements necessary for adequate performance in that application, and not based on this specification alone. 2 Normative references The following referenced documents are indispensable for the application of this document.
