Start with the identifier and status
Chinese lubricant requirements can appear in national standards and sector standards. Prefix, number, year and status matter. The official National Public Service Platform for Standards provides the primary status record for national standards.
A useful database entry therefore stores the exact Chinese and English title where available, document number, publication and implementation dates, responsible technical committee, adoption relationship to an international standard and current review conclusion.
Product scope comes before comparison
Two documents may use similar category language while applying to different engines, fuels, duty cycles, emissions hardware or test methods. A cross-reference should describe overlap and difference, not announce equivalence.
China VI is an emissions regime. It can influence engine and aftertreatment design, but it does not by itself give a universal finished-lubricant specification. The applicable vehicle-maker and oil requirements must be verified separately.
A defensible comparison method
Compare application, viscosity system, chemical limits, bench tests, engine tests, licensing or filing mechanism and OEM acceptance. Identify missing evidence explicitly.
Where an official English translation is unavailable, preserve the Chinese title and avoid translating technical requirements from secondary summaries as if they were authoritative text.
