1.1 本试验方法旨在提供一种评估船只护栏性能的方法，并通过该评估以ASTM国际冲击评级的形式提供用于船只护栏设计和规范的船只护栏性能认证。除冲击额定值外，本标准下的测试要求在测试期间确定和报告屏障的最大变形，以进一步帮助选择适当的屏障。 1.2 该测试方法提供了一系列小型水面机动船碰撞条件水平和穿透性能水平，以选择适合在潜在威胁的陆上港口设施、海上设施和浮动资产中使用的船只屏障。 1.3 本试验方法旨在测试和评估小型水面机动船碰撞点和碰撞后力矩处船只障碍物的停止能力。 1.4 本试验方法不适用于浮动“分界线”或类似项目或技术的试验标准，这些项目或技术不声称具有“船或小型水面机动船”的停止能力。 1.5 管理机构可在本试验方法中采用满足其特定需求的性能水平，并根据本试验方法中所述的试验和试验方法，为小型表面摩托艇停止障碍物指定认证等级。 1.6 许多测试参数被标准化，以获得常见的小型水面机动船类型和质量，增强测试的真实性和重复性，并产生统一的额定值。 1.6.1 遵守这些额定值设定了性能指标，但不会使任何船只障碍物免受摩托艇渗透的影响。在解释测试结果和将结果投影到其他假设条件时应谨慎。 1.7 本试验方法中的产品设计/认证仅涉及屏障承受试验摩托艇冲击的能力。 它不代表对产品/设计的认可，也不表示其操作适用性。 1.8 单位- 以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 1.9 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.10 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 政府和私人设施可使用ASTM国际冲击评级的“摩托艇护栏”。每个机构/组织可能有自己的或使用其他认证列表。 5.2 当需要进行动态测试时，本测试方法中的程序允许对船只屏障进行性能评估，以证明其对摩托艇攻击的防护水平。 5.3 除非经过本文所述的一个或多个动态试验，否则不得使用ASTM船护栏的故意冲击额定值。 5.4 小型和大型船只与各种安全设备的交互方式不同。此外，如果担心乘员风险，可以收集信息，以评估乘员受伤的可能性。

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. ====== 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.
