2. Testing body: a test laboratory approved by a domestic accreditation body approved by the competent authority to comply with CNS 17025 or ISO/IEC 17025.
3. Certification body: the competent authority or an institute delegated by the competent authority for the CTRFD approval.
4. Series product: a CTRFD or non-plug-and-play radio-frequency module（component）that is qualified in review without any change to the product in the original application and meets either of the following:
（1）No change to techniques used, such as power output, modulation technique, working frequency, number of channels and layout of circuit board containing major elements, with change（s）only to antenna, appearance, color, material, associated non-RF functions, power supply, accessory, brand or model;
（2）No change to RF hardware with change（s）only to modulation technique by firmware or software, reduction of power output, frequency range, bandwidth or number of channels.
5. Non-plug-and-play radio-frequency module（component）: a transmitter or transceiver that is provided with complete RF functionality but unable to operate independently; a transmitter or transceiver that is only installed on a specific platform for use is a restricted RF module（component）and one that can be installed on various platforms is a complete RF module（component）.
6. Platform: a device that that is fully functional even without a non-plug-and-play radio-frequency module（component）.
7. Final product: a CTRFD assembled from a non-plug-and-play radio-frequency module（component）and a platform; a restricted CTRFD assembled from a restricted RF module（component）and a platform is a restricted final product and a CTRFD assembled from a complete RF module（component）and a platform is a complete final product.
8. Approval certificate: a type approval certificate, declaration of compliance certificate, simplified declaration of compliance certificate or compliance approval certificate issued according to these Regulations.
9. Accessory: a signal cable or device connected to CTRFD or non-plug-and-play radio-frequency module（component）for normal use.
10. Peripheral: a piece of equipment connected to CTRFD or non-plug-and-play radio-frequency module（component）for normal use.
11. Test cable: a cable connected to CTRFD or non-plug-and-play radio-frequency module（component）for the purpose of testing.
12. Test fixture: a device attached to CTRFD or non-plug-and-play radio-frequency module（component）for the purpose of testing.

The review of a CTRFD shall be performed according to these Regulations, unless otherwise specified by law.
For radio station approval items specified in the administrative regulations for the management of radio stations promulgated according to Paragraph 9, Article 37, administrative regulations for dedicated telecommunication networks promulgated according to Paragraph 7, Article 50, and administrative regulations for amateur radio operators and stations according to Paragraph 2, Article 51 of the Telecommunications Management Act that include CTRFD approval or station approval that is replaceable for CTRFD approval, the requirements of respective regulations shall apply.

CTRFDs shall comply with the technical specifications established by the competent authority; for those for which the competent authority has not yet established the technical specifications, the following shall apply in the following order of priority:
1. Chinese National Standards（CNS）;
2. Standards established by an international standardization organization;
3. Standards established by a regional standardization organization.
For the criteria of electromagnetic compatibility or electrical safety in the technical specifications mentioned above, the requirements specified in other laws and regulations shall apply.
