 Latex has outstanding elastic properties : Its tensile strength exceeds 30 MPa , and latex condoms may be stretched in excess of 800 % before breaking . In 1990 the <unk> set standards for condom production ( <unk> <unk> , Natural latex rubber condoms ) , and the EU followed suit with its <unk> standard ( Directive 93 / 42 / EEC concerning medical devices ) . Every latex condom is tested for holes with an electric current . If the condom passes , it is rolled and packaged . In addition , a portion of each batch of condoms is subject to water leak and air burst testing .
