Accessories refer to parts or components of assembly machinery, and also refer to parts or components that are reinstalled after being damaged. Accessories can be divided into standard accessories and optional accessories. The service life of cars is very long, so both car companies and countries have this consideration.
In 2005, the General Administration of Quality Supervision, Inspection and Quarantine issued the "Three Guarantees Policy for Automobile", which requires that the after-sales service of automobile must meet the needs of users 10 years after the production of the whole vehicle stops. That is to say, within 10 years after the whole vehicle stops, the car enterprise must ensure that the car can be repaired with accessories if it is broken, so that it will not be repaired. Car companies will also sign relevant EOP(EndofProduction) spare parts agreements with spare parts suppliers, which is generally longer than the relevant national regulations.
