    This specification covers splices in vulcanized rubber-seal material of any size, type, or cross-sectional shape having applications in services of all degrees of severity. The splices under this specification are divided into three classes based on splice strength and the appearance of the seal. Under Class 1 are splices in seals having an irregular cross section or are made of polymers not conducive to a high-strength splice, and hence are appropriate for applications with moderate service requirements. Splices under Class 2 are those found in solid seals having a shape and composition conducive to a high-strength splice, and hence are appropriate for applications with high service requirements. Class 3 is comprised of splices in round solid seals conducive to extra-high-strength splices. Splices under this class are appropriate for applications with difficult service requirements; that is, applications requiring splices of extra-high tensile and bend strength. Quantitative destructive and qualitative nondestructive tests shall be performed on the spliced area of the seal and shall conform to the physical requirements specified, in particular the ultimate elongation for the seal area.

    Significance and Use

    6.1 These tests are used quantitatively, for evaluation, approval, and as a referee method. Also these tests are used qualitatively for quality control purposes.

    1. Scope

    1.1 This specification covers the strength and appearance of the splice in vulcanized rubber-seal material of any size, type, or cross-sectional shape.

    1.2 Many types and varieties of seals are used in services of all degrees of severity. In some instances, hollow tubing is spliced and used as a seal. It is also possible to have seals of irregular cross sections, or made of polymers which, due to their nature, or not conducive to a high-strength splice, although they will perform satisfactorily in their intended application.

    1.3 Seals are exposed in service to a wide variety of media at various temperatures. The effect of such media on the spliced area must be considered. Details of the test procedures to evaluate the effect of the media shall be agreed upon by the purchaser and seller as part of the purchase contract.

    1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

    1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

    1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
