New GB 18352.6-2016 for light-duty vehicles

The Chinese certification authorities MEP and SAC have published the new GB Standard GB 18352.6-2016, also called China VI:

GB 18352.6-2016  Limits and measurement methods for emissions from light-duty vehicles (China 6)

However, manufacturers have time to change their CCC Certificates to the new standard until Juli 2020, when the new GB Standard GB 18352.6-2016 will be implemented. This GB Standard is part of China’s initiative to reduce emission and will supersede the current GB Standard GB 18352.5-2013 Limits and measurement methods for emissions from light-duty vehicles (China 5).

If there are no new tests items, no tests will be required for the new GB Standard and it can be directly re-issued a new version of CCC Certificate. In case of new test items, additional tests regarding the differences are mandatory for the renewal of the new version of the certificate.

Before the end of the transition period, the production and certificates must be in compliance with the relevant laws and regulations.

In comparison to China V remain the limit values of HC, NMHC, NOx and PM by China 6a unchanged, while the limit values of CO are reduced and furthermore the limit value of N2O will be introduced:
