本SAE推荐规程建立了评估车辆发动机罩锁扣系统的统一试验程序。它特别适用于发动机罩上的闩锁系统，当发动机罩完全打开时（假设没有发动机罩挡块），该闩锁系统在水平面上方的任何点延伸，穿过直行驾驶位置的方向盘最上边缘，车辆处于水平位置。本推荐规程中概述的测试程序基于当前的工程测试方法。随着有关动态条件下车辆发动机罩锁扣系统性能的更多知识的开发，将定期审查和修订本报告的所有部分。

This SAE Recommended Practice establishes uniform test procedures for evaluating vehicle hood latch systems. It specifically pertains to those latch systems on hoods, which when the hood is fully opened (assuming the absence of hood stops) extend at any point above a horizontal plane through the uppermost edge of the steering wheel in the straight ahead driving position with the vehicle in a horizontal position. The test procedures outlined in this recommended practice are based on current engineering test methods. It is intended that all portions of this report will be periodically reviewed and revised as additional knowledge regarding vehicle hood latch system performance under dynamic conditions is developed.
