关于gb7258 2004 机动车运行安全技术条件 国家标准第1号修改通知单 经国家标准化管理委员会批准已正式发布 于2006年11月1日起实施 修改内容如下 一 删除第8 4 3条 前照灯的远 近光灯上下并列设置时 近光灯应位于上侧 其它情况下近光灯应位于外侧 的内容 二 第8 4 7 3条中的 在检验前照灯远光光束及远光单光束灯照射位置时 改为 在检验前照灯远光照射位置时 对于能单独调整远光光束的前照灯 gb4599update 本标准代替gb4599 94 汽车前照灯配光性能 与前者相比主要变化如下 增加了hs1 hb3 hb4 h7 h8 h9 h11 hir1和hir2类型灯泡 半封闭式前照灯应使用符合gb15766 1或ecer37规定的灯丝灯泡 对于半封闭式前照灯 近光暗区增加了八个测试点 增加弯道照明的内容 增加了反射镜可调节的半封闭式前照灯配光性能试验方法 增加了附录a 前照灯的配光性能稳定性试验 增加了附录b 塑料配光镜前照灯的要求 配光镜或材料试样和整灯试验 增加了附录c 试验程序 增加了附录d 漫射光和透射光的测量方法 增加了附录e 机械磨损试验方法 增加了附录f 粘胶带附着力试验 lightingfunction lightingtechnologies parabola
