1.1 本规程旨在提供选择、集成和验证主动式车辆护栏安全装置的方法，以便在运行时可靠、安全地控制车辆护栏系统。 1.2 主动车辆安全栅系统（AVB）的操作和使用存在许多风险。其中一个风险是主动车辆护栏（AVB）与授权车辆之间发生意外碰撞。通过适当的设计、施工、安装、操作和使用此类系统的培训，可以将此类风险降至最低。 1.3 正确选择、安装和使用安全装置，以防止授权车辆在通过障碍物时激活或部署AVB，或当车辆的一部分位于障碍物的路径上或不安全的接近障碍物时，此类授权车辆停止，可以最大限度地减少障碍物和授权车辆之间发生意外碰撞的可能性。 1.4 在本实践中，安全性是指当授权车辆通过障碍物时，障碍物在操作或部署时不会对车辆造成意外损坏或对人员造成伤害的能力。安全性是指操作或部署障碍物的能力，以达到阻止未经授权的车辆通过障碍物位置的预期目的。 1.5 行人不在本惯例范围内。就本实践而言，假设行人不在AVBS移动部件附近的潜在危险位置。人们认识到，出于必要的目的，授权行人可能出现在可移动AVB区域，例如检查停车的车辆。 “临时”行人应远离AVB的可移动元件。 1.6 本规程无意解决以下任何问题: 1.6.1 车辆屏障系统的整体性能或作为任何车辆屏障的有效性（见试验方法 F2656/F2656M ). 1.6.2 车辆护栏系统能够承受的冲击能量。 1.6.3 屏障系统的可用性。 1.6.4 为任何特定用途选择车辆屏障系统。 1.6.5 行人检测安全装置- 该实践认为，行人被排除在车辆护栏系统附近的危险区之外；当主动障碍物运行时，只有经过培训和授权的人员，如执行必要功能的维护人员和安保人员，才会出现在危险区域。 1.6.6 车辆屏障系统的设计和安装，而不是相关车辆检测安全装置的性能，以及验证安全装置是否能够在指定的紧急情况下根据车主的要求被超越。 1.6.7 一旦安装并投入使用，主动车辆护栏系统的操作程序或操作说明。尽管此类操作程序对于AVB在实践中的安全操作至关重要，但此类程序的制定和实施超出了本实践的范围。 1.7 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。 1.8 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====== 4.1 过去曾发生过授权车辆与AVB之间发生意外碰撞的情况。正确选择、设计和安装的安全装置能够在授权车辆位于危险检测空间且直接靠近障碍物时抑制主动障碍物的部署，可以将此类事故发生的可能性降至最低。 4.2 意外障碍物/车辆碰撞可能非常危险，经常会导致重大财产损失，也可能导致人身伤害或死亡，具体取决于事件周围的情况。 4.3 人们认识到，某些车型可能无法通过单个检测设备进行可靠检测，即使并非所有车型都可以可靠检测，车主也可能希望将AVB投入使用。在确定使用时，业主应仔细考虑此类系统性能限制和安全风险、将安全危害降至最低的适当替代控制措施，以及在将设备投入使用之前能够接受的风险。本规程旨在向业主、设计师、安装商、集成商和设备供应商提供对此类决策可能重要的信息，但其目的不是确定哪些风险/危害是可接受的。 4.4 人们还认识到，在某些特殊情况下，业主可能会确定在AVB中安装安全装置是不可接受的。例如，在某些情况下，对所有者而言，安全风险可能比可能的安全隐患更为重要。在这种情况下，业主应接受与确定不使用安全装置相关的安全风险和可能后果。 4.5 如果业主确定不使用安全装置，则业主可能会选择实施一些替代方法来缓解或减少部分安全风险。

1.1 This practice is intended to provide methods for selecting, integrating, and verification of active vehicle barrier safety devices so that vehicle barrier systems are reliably and safely controlled when in operation. 1.2 There are a number of risks associated with the operation and use of active vehicle barrier systems (AVBS). One of the risks is that of undesired collision between an active vehicle barrier (AVB) and an authorized vehicle. Such risks can be minimized through proper design, construction, installation, operation, and training in the use of such systems. 1.3 The proper selection, installation, and use of safety devices that will prevent an AVBS from activating or deploying while an authorized vehicle is transiting the barrier, or when such an authorized vehicle is stopped while a portion of the vehicle is located in the path of or in an unsafe proximity to a barrier, can minimize the likelihood of unintended collision between a barrier and authorized vehicle. 1.4 For this practice, safety refers to the ability of the barrier to operate without causing unintended damage to vehicles or injury to people via operation or deployment of the barrier, when an authorized vehicle is transiting the barrier. Security refers to the ability to operate or deploy the barrier to serve its intended purpose of stopping an unauthorized vehicle from passing through the barrier location. 1.5 Pedestrians are excluded from the scope of this practice. It is assumed, for the purposes of this practice, that pedestrians are excluded from potentially hazardous locations in the immediate vicinity of AVBS moving components. It is recognized that authorized pedestrians may be present in the area of the movable AVBS for required purposes, such as inspection of vehicles that are stopped. The presence of “casual” pedestrians shall be kept away from the movable elements of the AVBS. 1.6 This practice is not intended to address any of the following: 1.6.1 Overall performance of vehicle barrier systems or effectiveness as a barrier against any vehicles (see Test Method F2656/F2656M ). 1.6.2 Impact energy able to be withstood by vehicle barrier systems. 1.6.3 Serviceability of barrier systems. 1.6.4 Selection of vehicle barrier systems for any particular use. 1.6.5 Pedestrian Detection Safety Devices— This practice considers that pedestrians are excluded from hazard zones in the vicinity of vehicle barrier systems; and that only trained and authorized people, such as maintenance staff and security officers performing necessary functions, will be present in the hazard areas when the active barriers are in operation. 1.6.6 Design and installation of vehicle barrier systems, other than performance of associated vehicle detection safety devices, and the verification that safety devices are able to be overridden under designated emergency conditions, as required by owners. 1.6.7 Operating procedures or instructions for operational use of active vehicle barrier systems once they are installed and placed into service. Although such operating procedures are essential for the safe operation of AVBS in practice, development and implementation of such procedures is beyond the scope of this practice. 1.7 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. 1.8 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 ====== 4.1 There have been instances in the past in which undesired collisions between authorized vehicles and AVBS have occurred. Properly selected, designed, and installed safety devices that are able to inhibit deployment of active barriers when authorized vehicles are in the hazard detection space, in direct proximity to the barrier, can minimize the likelihood that such accidents occur. 4.2 Unintended barrier/vehicle collisions can be very hazardous, will frequently result in significant damage to property, and can also result in personal injury or death, depending on conditions surrounding an incident. 4.3 It is recognized that some vehicle types may not be reliably detected by an individual detection device and an owner may desire placing AVBS in service even though not all vehicle types may be reliably detected. In such determination of use, an owner shall carefully consider such system performance limitations and safety risks, appropriate alternative controls that will minimize safety hazards, and what risks are able to be accepted before placing equipment into service. This practice is intended to provide the owners, designers, installers, integrators, and equipment providers with information that may be important to such decisions, but it is not intended to determine what risks/hazards are acceptable. 4.4 It is also recognized that there may be particular conditions in which an owner may determine that it is not acceptable to have safety devices installed in AVBS. For example, there may be conditions under which the security risks are determined to be more important to an owner than the possible safety hazards. In such circumstances, the owner shall accept the safety risks and possible consequences that are associated with such a determination that safety devices will not be used. 4.5 If an owner determines that safety devices are not to be used, then it is possible that the owner may choose to implement some alternate means to mitigate or reduce a portion of the safety risks.
