Abstract
A method of testing an elastomeric personal barrier which involves positioning the barrier over a mold in the shape of the barrier, the mold being translucent or of a contrasting color to the barrier, exposing the personal barrier to a non-corrosive solvent so that the solvent comes into contact with the exterior of the personal barrier only except where a flaw exists in the barrier, removing the personal barrier from contact with the solvent, and inspecting the exterior of the personal barrier for the appearance of one or more stains which indicate the presence of a flaw in the structural integrity of the barrier.
Claims17
A method for testing the integrity of a personal barrier, which comprises:
- (a) positioning a personal barrier over a mold, the mold being in the shape of the personal barrier;
- (b) exposing the personal barrier to a non-corrosive solvent, wherein the solvent comprises a liquid with a surface tension less than or equal to 50 dyn/cm at 20.degree. C., such that the solvent comes into contact with the exterior surface of the personal barrier only and is free to penetrate into or through any flaws thereon;
- (c) removing the personal barrier from contact with the solvent;
- and
- (d) inspecting the exterior surface of the personal barrier for one or more stains at location(s) through which the solvent had penetrated which indicate the presence of a flaw or flaws in the structural integrity of the barrier.
A method for testing the integrity of a personal barrier, which comprises the steps of:
- (a) positioning a personal barrier over a mold shaped as the personal barrier;
- (b) exposing the personal barrier and mold to a non-toxic and non-corrosive solvent having a surface tension less than or equal to 50 dyn/cm at 20.degree. C., such that the solvent comes into contact with the exterior surface of the personal barrier only and is free to penetrate into or through any flaws thereon;
- (c) removing the personal barrier from contact with the solvent;
- and
- (d) inspecting the exterior surface of the personal barrier for one or more stains at location(s) through which the solvent has penetrated which indicate the presence of the flaw or flaws in the structural integrity of the personal barrier.
