Scope
GB 14622-2026 is the English-translated version of 摩托车污染物排放限值及测量方法（中国第五阶段）.
GB 14622-2026 is the China V motorcycle emission standard, and at 89,500 words it is the largest document in this part of the catalogue. It replaces both GB 14622-2016 and GB 18176-2016, folding motorcycles and mopeds into one regime, and adds what the previous stage lacked: requirements for hybrid powertrains, a reinforced on-board diagnostic system, in-service conformity and an end-of-line inspection. The long lead time is deliberate — issued on 27 February 2026, it does not take effect until 1 January 2029, which is the runway manufacturers have to recertify their ranges. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the edition it replaces are taken from there. The clause text, the tables and the numeric limits are not reproduced on this page — they are in the document itself, which is delivered in full in English translation.
