BS 903 Part A4858 is identical to ISO 4647 and Part A 5659 identical to ISO 5603. It is significant that the equivalent ASTM standards are not produced under the auspices of the committee for rubber but in a subcommittee of the textiles committee specifically covering tyre cord and fabrics. The H-test is in D477660 and the method for steel cord in D222961. There is also a method for strap peel adhesion test of reinforcing cords or fabric in D439362.

Other Materials. The acrylic D, Hypalon E, and Butyl F caulking compounds were too weak and tacky for the tensile testing technqiues employed and thus were not evaluated in these tests. (Peel adhesion tests, a topic of a future paper, were employed in monitoring the hydrolytic stability of these soft caulking compounds).

Most of the testing we did early on was pretty simple. There are three basic properties of all pressure-sensitive adhesives peel, tack and shear. Most of the testing we did was pretty limited to peel adhesion tests, tack tests and shear tests. We weren t doing a lot of application-related testing. Testing was done in lab conditions on stainless steel test panels, and customers were trying to translate that information into whether the adhesive would actually perform on their specific substrate.

It should be emphasized that peel adhesion test is only an indirect indicator of actual plate adhesion the correlation between peel adhesion values and pass/fail in thermal cycle and/or thermal shock is quite weak. The lower limit of 5 Ib/in is based on empirical data. Values greater than 10 Ib/in are routinely seen for ABS or ABS-rich...
