Standard Test Methods for Tensile Strength Characteristics of Oil Spill Response Boom
SCOPE
1.1 These test methods cover static laboratory tests of the strength of oil spill response boom under tensile loading.
1.2 This standard does not purport to address all of the safety problems 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. For a specific hazard statement, see Section 8.
