Take two 0-rings of the same size, as specified in 8.1.2, prepared as specified in 10.2, and two metal strips of dimensions 50 mm by 100 mm, prepared as specified in 10.4. Place the 0-rings between the prepared surfaces of the metal strips so that they are approximately 40 mm apart and approximately equidistant from the ends of the metal strips. Align the metal/rubber sandwich so formed in the support jig and apply a load L in accordance with Table 2 to the test piece sandwich. Tighten the two screw clamps, one at each end of the sandwich, with just sufficient force to maintain the clamping force when the load is removed. Remove the load from the jig, place the sandwich in the test chamber (5.3) and maintain it at the test temperature for the test period (see Clause 9).
At the end of the test period, remove the sandwich from the test chamber, allow to cool, if appropriate, to standard laboratory temperature and maintain it at this temperature for at least 1 h. Release the screw clamps and carefully separate the metal strips from the rubber O-rings. Examine the surface of the metal previously in contact with the rubber for signs of adhesion and corrosion. Use a magnifying glass (5.5) in examining for corrosion.
