4.1 This test method describes a procedure for evaluating rubberized fabrics that are used to manufacture pneumatic articles (that is, those that must retain air in order to perform satisfactorily in an intended application). Examples of such articles are emergency rafts, life preservers, marine recreational equipment, floats, pontons, and warning or detection devices, such as buoys or weather balloons.

1.1 This test method describes the determination of the retention of air by fabrics coated on one or both sides with rubber.

1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

1.3 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.4 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.
