SAE推荐规程的范围和目的是为额定车辆总重超过4540 kg（10000 lb）的液压制动车辆提供停车制动器的控制和指示标准。本推荐规程适用于自动变速器应用，并补充了SAE J915推荐规程。此推荐做法不涉及驻车制动系统性能。驻车制动系统性能（静态和动态）由OEM车辆制造商或通过添加特殊职业要求设备（如但不限于支腿、起重机等）改装车辆的制造商负责。

The scope and purpose of the SAE Recommended Practice is to provide standards for the control and indication of parking brakes in hydraulic braked vehicles over 4540 kg (10000 lb) GVWR. This recommended practice pertains to automatic transmission applications and supplements the SAE J915 recommended practice. This recommended practice does not address parking brake system performance. Parking brake system performance, both static and dynamic conditions, is the responsibility of the OEM vehicle manufacturer or manufacturers that modify the vehicle by adding special vocational required equipment (such as but not limited to outriggers, cranes, etc.).
