This test standard shall be used to determine the resistance to peel of tapes and foils consisting of pressure sensitive adhesive coated fabrics,

4、plastics, paper etc. intended for applications involving adherence to painted automobile body panels. 1.2 Applicability. This test method shall apply to the time of measuring self adhesive tapes and foils that applied to the automobile. 2 References Note: Only the latest approved standards are appli

The resistance to peel shall be calculated as the average of the separating force recorded on the force extension diagram, ignoring the first 25 mm and last 25 mm of separation, expressed in N/cm widt

10、h of test piece. 5.2 Expression of Results. With reference to this test method the resistance to peel shall be expressed as the arithmetic average of three test results or as the individual result (single test) in N/cm width rounded to the nearest 0.1 N/cm width. 6 Safety This standard may involve h

11、azardous materials, operations, and equipment. This standard does not propose to address all the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitatio

Resistance to Peel: As determined by this test method, shall be defined as the force, acting at approx. 180 and parallel to a test piece of standard dimensions adhered to a painted steel panel, necessary to “peel“ the test piece from the panel. 7.2 Acronyms, Ab
