The central competent authority, after having accepted the compliance certification application as set forth in the foregoing paragraph, shall complete the inspection and issuance of the compliance certification within 20 days. If the information in an application does not comply with regulations, said application shall have a limited period in which to make the necessary corrections; the number of days for making corrections shall not be calculated within the review period and the number of days for making corrections may not exceed 30 days.
The central competent authority may enter the applicant's inspection room, factory and sales office to inspect if the relevant records are consistent with the design specifications contained in the application while performing the examination of the preceding paragraph; and send personnel or designated professional organizations to jointly inspect their vehicles for vehicle examinations, inspection, maintenance or sales adjustment process.

Article 6
Noise inspection reports submitted in application for compliance certification pursuant to Appendix 1 shall, according to Article 5, choose a representative vehicle pursuant to Appendix 2 and shall be limited to those analysis and testing organizations designated by the central competent authority.

The items and expenses for processing of testing examination number, and examination of video record and transmission shall be submitted and approved by the central competent authority.

Article 7
An applicant who plans to continue manufacturing or importing in the following year a motor vehicle that has already obtained compliance certification shall apply to the central competent authority for continued use of the compliance certification in the following model year.
Applicants may be issued a renewed compliance certification after the following information has been verified and approved for compliance by the central competent authority:
I.  The vehicle model is identical to the previous vehicle model.
II. The impact of noise from the vehicle model is identical to that of the model from the previous year, or the next vehicle model year has already been issued compliance certification from a European Union member country or UK.

Article 8
Applicants making partial revisions to vehicle type configuration information and continuing to use the original vehicle type configuration shall apply with central competent authority to make the necessary revisions to the compliance certification.
Applicants may be issued a revised compliance certification after the following information has been reviewed and approved for compliance by the central competent authority:
