This Section of BS 5131 describes a method for determining whether moulded-on rubber soles have been satisfactorily vulcanized. Because of the method of manufacture, the outer side of the sole adjacent to the heated metal mould is fully cured but the inner side, next to the insole, is usually not fully cured. Some undercure next to the insole is acceptable and even desirable to ensure good adhesion; the purpose of this test is to establish that the undercure is not excessive. The test is suitable for routine quality control work and is simple to carry out.

Any direct moulding compound which shows a significant difference in hardness between the cured and uncured state can be tested by this method.
