WTO.美国通报重型发动机和车辆试验程序的改进及其他技术修订
编号：G/TBT/N/USA/1620
拟议规则-环境保护署（EPA）正在提议修改重型发动机和车辆的测试程序，以提高准确性和减少测试负担。环保署还提议对轻型车辆、重型车辆、公路摩托车、机车、船用发动机、其他非公路发动机和车辆、固定发动机进行其他法规修订。这将影响废气排放标准的认证程序和相关要求。美国环保署正在对非道路设备和便携式燃料容器的蒸发排放标准提出类似的修正案。这些修正案将增加合规灵活性，与其他要求协调一致，增加透明度，纠正错误，并精简条例。鉴于拟议的变化的性质，这些变化对任何部门既不会产生重大的环境影响，也不会产生重大的经济影响。
涵盖的产品：重型发动机和车辆；火花点火往复式或旋转式内燃机（HS 8407）；压燃式内燃机（柴油机或半柴油机）（HS 8408）；运输10人或10人以上的机动车，包括驾驶员（HS 8702）；主要设计用于运送人的汽车和其他汽车（87.02除外），包括旅行车和赛车（HS 8703）；用于运送货物的汽车（HS 8704）；主要设计用于运送人或货物的特殊用途汽车（例如，故障卡车（粉碎机）、起重机卡车（移动式起重机）、消防车、混凝土搅拌车（混凝土搅拌车）、道路清扫车（道路清扫车）、喷洒车（喷洒车）、移动车间、移动辐射装置（HS 8705）；质量（ICS 03.120）、空气质量（ICS 13.040）、一般试验条件和程序（ICS 19.020）、一般道路车辆（ICS 43.020）、商用车辆（ICS 43.080）、乘用车。大篷车和轻型拖车（ICS 43.100）
英文原文：
Proposed rule - The Environmental Protection Agency (EPA) is proposing changes to the test procedures for heavy-duty engines and vehicles to improve accuracy and reduce testing burden. EPA is also proposing other regulatory amendments concerning light-duty vehicles, heavy-duty vehicles, highway motorcycles, locomotives, marine engines, other nonroad engines and vehicles, stationary engines. These would affect the certification procedures for exhaust emission standards, and related requirements. EPA is proposing similar amendments for evaporative emission standards for nonroad equipment and portable fuel containers. These amendments would increase compliance flexibility, harmonize with other requirements, add clarity, correct errors, and streamline the regulations. Given the nature of the proposed changes, they would have neither significant environmental impacts nor significant economic impacts for any sector.
