CEN发布有助于空气更清洁的CEN研讨会协议--CWA 17379:2019

发布时间: 2019-03-13 14:27:07   审校:睿智  

CEN研讨协议CWA 17379:2019 编制可比排放数据真实驾驶试验方法通用指南是欧洲标准化组织为改进欧洲空气质量,特别是针对城市地区空气质量改进发挥作用的最新实例。这项标准首次提供了一种在欧洲各地得到认可的用于对汽车和货车进行道路测试的测试方法及指南,以获取城市氮氧化物(NOx)的排放数据。特别是,协议中描述的方法和要求确保了使用便携式排放测量系统(PEMS)进行的测试的统一性。这样收集的数据将使来自不同测试中心的不同车辆的排放性能得到公平的比较。

自2017年9月1日起,所有新推出的汽车的型式认可都要进行道路测试,作为最新排放标准的一部分,称为RDE(实地驾驶排放标准)。这项标准由欧洲认证程序开发和执行,以确保车辆在各种驾驶环境下正常气体排放不超过规定的限值。

CWA 17379:2019是基于RDE方法制定的,它规定了城市驾驶过程中车辆实际气体排放的记录过程,以正确比较不同车辆的道路排放性能。该项标准测试要求严格,需在三段独立的行程中对每个型号的车辆进行至少两次匹配测试,在公路上进行至少五次10千米的行程测试,测试速度平均需控制在20-40千米每小时之间。

使用这一方法有利于检测结果的透明度,能够有效监测市区驾驶期间车辆的氮氧化物(NOx)排放,从而使汽车的购买者、政策制定者和其他利益相关方能够就车辆的选购和城市空气质量的结果做出更明智的决策。

CEN CWA 17379:2019于2019年1月30日是由CEN / WS 090“收集实地驾驶中气体排放数据的测试方法”技术委员会发布。该项研讨会协议在排放分析(Emissions Analytics)创始人、独立道路测试(Allow Independent Road-testing,AIR)联合创始人尼克莫尔登(Nick Molden)的主持下,由40多位科学家同消费者团体、政策制定者、工程师,非政府组织和欧盟委员会通力合作,并最终完成。CEN / WS 090的秘书处是由意大利国家标准化组织(UNI)承担。想获悉更多的国内外标准信息,请访问中国标准信息服务网(<https://www.sacinfo.cn>)。

CWA 17379:2019: A new CEN Workshop Agreement helps make our air cleaner 

CEN Workshop Agreement CWA 17379:2019 ‘General guideline on real drive test methodology for compiling comparable emission data’ is the latest example of the active role of standardization in improving air quality for all Europeans, especially in urban areas. For the first time ever, the publication provides a testing methodology and guidelines recognised all over Europe to conduct on-road testing of cars and vans to capture data on emissions of urban nitrogen oxides (NOx). In particular, the methods and requirements described in the agreement ensure that the test procedure, conducted using Portable Emissions Measurement Systems (PEMS), is consistently applied. The data thus collected will enable emissions performance of different vehicles, across different test centres, to be fairly compared.

Since the 1st of September 2017, the type approval of all newly introduced cars includes on-road testing as part of the latest emissions standard known as RDE (Real Driving Emissions). This European certification process was developed and implemented to ensure modern vehicles do not exceed the prescribed emissions limits in normal use across a range of driving conditions.

CWA 17379:2019 builds upon the RDE methods and describes the process to test the actual emissions recorded during urban driving, with the aim of comparing the on-road emissions performance of different vehicles fairly. The stringent requirements introduced demand the testing of at least two matching examples of each model, during three separate journeys, including at least five 10km trips conducted on paved roads, at an average speed between 20km/h and 40 km/h.

The results produced using this methodology provide transparency regarding the on-road NOx emissions produced from vehicles during urban driving. This enables car buyers, policy makers and other stakeholders to take better informed decisions about vehicle choices and the consequences for urban air quality.

CEN CWA 17379:2019 was published on 30 January 2019 by CEN/WS 090 “Real drive test method for collecting emission”. The agreement is the result of a collective dialogue between more than 40 scientists, consumer groups, policy makers, engineers, NGOs and the European Commission, working together under the chairmanship of Nick Molden, founder of Emissions Analytics and co-founder of Allow Independent Road-testing (AIR). The Secretariat of CEN/WS 090 was held by UNI, the Italian National Standardization Body.
