Set the recorder chart for approximately half the crosshead speed. Straps are cut from the cured pad in its long direction parallel to the cords, and the force to peel one fabric layer from the other is determined in a recording tensile test machine. Separate straps are prepared for warp and across-warp direction except in special cases see Your Alert Profile lists the documents that will be monitored.
The more usual and convenient method for acceptance testing of such single cords is to prepare from a shipment a test piece or article in the same manner as the commercial article to be produced and to test cord-adhesion characteristics in this piece in a manner that compares its adhesion characteristics against a previously established, acceptable control.

For steel cord, it may be required to use a backing fabric in place of the additional rubber or portion thereof in order to maintain integrity of the specimen during peeling on the tensile test machine. Combining values from ast two systems may result in non-conformance with the standard. Either system of units may be used in asym test method.
The force to peel one fabric layer from the other is determined in a recording tensile testing machine. With the specimen in the jaws of the tensile testing machine and under a tension less than that required to peel the specimen, stop the crosshead and cut through the rubber separating the two fabric layers to x4393 surface of one of the fabric layers.
The testing machine shall be equipped with an autographic recorder rectilinear coordinates preferred and? Remove the specimen from the hot mold as quickly as possible and air-cool the specimen.
