Some Areas may Practice “National Sixth” Standards ahead of Time
National Sixth Standards, acting as upgraded standards for National Fifth Standards, are set based on global technical regulations and have a stricter testing procedure than European standards.
Liu Bingjiang, Director of Atmospheric Environmental Management Department of the Ministry of Environmental Protection, said that l National Sixth A Standards are stricter than European standards but lower than American Tier 3 emission limit level. National Sixth B standards have almost the same level with average limits from American Tier 3 standards. Considering the different testing procedure and the introduction of RDE regulation and PN limits, National Sixth Standards are one of the strictest emission standards across the world.
Only less than four years are left for the implementation of National Sixth standards, which displays a great challenge. Besides, the tight schedule and long system development cycle accumulates more risks. It’s known that most auto companies are actively addressing with such problems by investing funds and human resources to develop new products. Besides, some cities or areas may implement the National Sixth standards ahead of time.
