BS 1464:2010 pdf download – Adhesives — Determination of peel resistance of adhesive bonds — Floating roller method 1Scope This European Standard specifies a floating roller method for the determination of the peel resistance ofadhesive bonds between one rigid adherend and one flexible adherend when tested under specifiedconditions of preparation and testing. NOTE The use the floating roller produces more constant numerical data than other peel methods, but it should notbe expected that the flexible adherend will conform to the surface of the roller. SAFETY STATEMENT—Persons using this document should be familiar with the normal laboratory practice,if applicable. This document does not purport to address all of the safety problems, if any, associated with itsuse. lt is the responsibility of the user to establish appropriate safety and health practices and to ensurecompliance with any regulatory conditions. ENVIRONMENTAL STATEMENT — lt is understood that some of the material permitted in this standard mayhave negative environmental impact.As technological advantages lead to acceptable alternatives for thesematerials, they will be eliminated from this standard to the extent possible. At the end of the test, the user of the standard should take care to carry out an appropriate disposal of thewastes, according to local regulation.
