Mobile hard disk mainly refers to the use of USB or IEEE1394 interface, which can be plugged in or unplugged at any time, compact and portable hard disk storage, which can transmit data with the system at a higher speed. However, in general, these products need to apply for SRRC certification if they want to be sold on the Chinese market. However, in order to avoid detours in the process of applying for SRRC certification, general merchants will conduct SRRC pre-test before doing SRRC certification.

What is SRRC certification?

SRRC certification is a mandatory wireless certification in China. Name: China Radio Transmission Equipment Type Approval Certificate. It is a compulsory certification for electronic products with wireless, Bluetooth, and transmitting frequency. It is tested by a national designated laboratory and certified by the national laboratory.

SRRC is a mandatory certification requirement of the National Radio Regulatory Commission. Since June 1, 1999, the Ministry of Information Industry (MII) of China has mandated that all radio component products sold and used in China must obtain a radio model Radio Type Approval Certification (Radio Type Approval Certification). Domestically produced, sold and used radio transmission equipment must be type approved, and the approval certificate and type approval code must be issued, and the type approval code must be indicated on the label of the factory equipment.

The main content of the mobile hard disk SRRC pre-test

Since the radio transmission power supported by different products is different, the required detection content also needs to be developed in a targeted manner.

Test items: transmit power, spectrum range, frequency tolerance, bandwidth, spurious radiation, etc.

Certified product types: public mobile communication equipment, wireless access systems, private network equipment, microwave equipment, satellite equipment, radio and television equipment, 2.4GHz/5.8 GHz wireless access equipment, radar and other radio transmission equipment.

If there are individual types that are not included, the test can also be prepared with reference to the above similar equipment.

Materials to be prepared for mobile hard disk SRRC pre-test application

1. "Application Form for Approval of Radio Transmission Equipment Models"; if there is an agency applying unit, a "Power of Attorney for Approval of Radio Transmission Equipment Models" shall also be submitted;

2. Test protocol in triplicate;

3. Test sampling in duplicate;

4. Antenna gain and line loss statement;

5. Submit a copy of the "Corporate Legal Person Business License" of the applying unit (including the agency applying unit);

6. Equipment photos and nameplate diagrams; the final materials need to be submitted:

7. Submit the technical specification (including the software and hardware version number) and user manual of the bid equipment model;

8. Submit the circuit diagram and block diagram of the tested equipment;

9. The manufacturer’s ISO9001 certificate, if the ISO certificate of the factory OEM is provided, the manufacturer’s commissioned OEM certificate shall be issued.

Mobile hard disk SRRC pre-test application process

1. After the "Radio Transmission Equipment Type Approval Inspection Report", submit the application materials for the "Radio Transmission Equipment Type Approval Certificate".

2. Download the "Application Form for Radio Transmission Equipment Model Approval" from the radio transmission equipment model approval website; the agency applying unit needs to download the "Authorization Letter for Radio Transmission Equipment Model Approval" at the same time.

3. The application materials for type approval of radio transmission equipment must be provided in Chinese or English, and materials in other languages must be translated into Chinese or English (the translation unit/department should affix the official seal).

4. The applicant unit or agency application unit applies online, and waits patiently for the certificate after the submission of the documents is accepted. If the submitted information is unqualified, it will usually be returned soon, and it will take time to pay attention.

5. The administrative licensing decision shall be made within 20 working days from the date of accepting the application for model approval.

6. After the applicant unit has obtained the "Radio Transmission Equipment Type Approval Certificate" and its approval code, the manufacturer should indicate the radio transmission equipment type approval code (clearly visible during normal installation) on the approved equipment label. It is true that the equipment is too small. If the approval code cannot be marked on it, the model approval code of the device shall be posted in the product manual or user manual.
