(Test Method)Standard Test Method for Boat Barriers
Standard Test Method for Boat Barriers
SIGNIFICANCE AND USE
5.1 Governmental and private facilities may use “motor boat barriers” with an ASTM International impact rating. Each agency/organization may have their own, or use other, certification lists.
5.2 When dynamic testing is required, procedures in this test method permit performance evaluation of a boat barrier to certify its level of protection against motor boat attack.
5.3 ASTM Intentional Impact Ratings for Boat Barriers shall not be used unless subjected to one or more of the dynamic tests presented herein.
5.4 Small and large boats interact differently with various security devices. Additionally, if occupant risk is of concern, information may be gathered that allows assessment of the likelihood of occupant injury.
SCOPE
1.1 This test method is intended to provide a means of evaluating the performance of Boat Barriers and through that evaluation provide a certification of performance in the form of an ASTM International Impact Rating for Boat Barriers to be used in the design and specification of Boat Barriers. In addition to the Impact Rating, testing under this standard requires the determination and reporting of the maximum deformation of the barrier during testing to further aid in appropriate barrier selection.
1.2 This test method provides a range of small surface motor boat impact condition levels and penetration performance levels to select boat barriers appropriate for use at potentially threatened onshore port facilities, offshore facilities, and floating assets.
1.3 This test method is designed to test and evaluate the stopping capabilities of boat barriers at the point of impact and the moments subsequent to impact of a small surface motor boat.
1.4 This test method is not intended to be used for the testing criteria of floating “lines of demarcation” or similar items or technologies that do not make claims of “boat or small surface motor boat” stopping capabilities.
1.5 Governing agencies may adopt those performance levels in this test method that satisfy their specific needs and assign certification ratings for small surface motor boat stopping barriers based on the tests and test methodologies described in this test method.
1.6 Many test parameters are standardized to arrive at common small surface motor boat types and masses, enhance test realism and replications, and produce uniform rating designations.
1.6.1 Compliance with these rating designations establishes a measure of performance but does not render any boat barrier invulnerable to motor boat penetration. Caution should be exercised in interpreting test findings and projecting results to other hypothetical conditions.
1.7 Product design/certification in this test method only addresses the ability of the barrier to withstand the impact of the test motor boat. It does not represent an endorsement of the product/design or address its operational suitability.
1.8 Units—The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.9 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.
1.10 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.
