(Note: The CCS number in the standard is based on the "Chinese Standard Document Classification Number" used in the regulatory authority system. The classification number used in this platform's database is the 2017 edition of the National Economic Industry Classification Number. The two systems use different classification numbers. When uploading the standard text to this platform, the classification number is selected according to the platform's classification number, so after downloading the standard text, you may notice that the CCS number does not match the one selected in this system.)
