Preparation of test sheets and pieces from manufactured soles or soling materials or from mouldable or vulcanizable materials. Time intervals between preparation of sheets and cutting of test pieces.

This Section describes the general procedures for the preparation of the test piece from shoe soles or soling materials, required for the physical tests of solings covered by other Sections of this British Standard and for the tests relevant to solings in BS 903 and BS 2782. It does not describe the preparation of the special test pieces that are required for certain Sections of this British Standard. These are either described in the Sections concerned or, in the case of the preparation of test pieces for adhesion tests, in Part 1.

This Section describes methods for the reduction of moulded soles or soling in sheet form to a uniform sheet of the thickness required for testing, the production of test slabs from injection mouldable or vulcanizable materials, the cutting of test pieces from the sheet or slab, and the time intervals that need to be allowed between sheet preparation and test piece cutting.
