ISO 29864-2018 自粘膠帶--斷裂強度和斷裂伸長(cháng)率的測量 Self adhesive tapes — Measurement of breaking strength and elongation at break

This document specifies methods to measure the breaking strength and elongation at break of a self adhesive tape when it is subjected to a tensile force sufficient to cause it to break.
These test methods describe a procedure for testing 12 mm or 24 mm wide samples cut from supplied rolls of self adhesive tapes. Alternatively rolls of self adhesive tape up to 50 mm wide can be directly tested in their original width. In these circumstances the practical breaking strength and elongation will be typical of the manufacturer’s cut edges. When newly cut sample pieces are tested, because of the better cutting of the edges, the results can be higher than would be found on commercial tape.nd edition 2018-05 Self adhesive tapes — Measurement of breaking strength and elongation at break Rubans auto-adhésifs — Mesure de la résistance à la rupture et de l'allongement à la rupture Reference number ISO 29864:2018(E) ？ ISO 2018 ISO 29864:2018(E) COPYRIGHT PROTECTED DOCUMENT ？ ISO 2018 All rights reserved.
