Testing for SRRC (State
Radio Regulatory Commission) certification must be carried out in an accredited lab
in China. After the testing is done, the SRRC will review the report and
proceed with approval/ rejection.
In order to increase the chances of
application success, your product must meet all the required technical
specifications. It includes stray radiation, transmitting power, bandwidth and
frequency.
Frequency is one of the most
important features. Make sure your products fulfill all these requirements.
As such, devices are classified into
7 categories, according to the mentioned technical specifications. Here’s a
short review of these product categories; magnetic field strengths are described
as quasi-peaks.
- Type A - They have a frequency ranging from 9kHz to 190kHz and magnetic field strength is in following ranges:
- 9kHz to 50kHz: 72dBμA/m in 10 meters distance
- 50kHz to 190kHz: 72dBμA/m in 10 meters distance with 3dB decrease per octave
- Type B - Frequency ranges from 1.7MHz to 9.9Mhz. Magnetic strength is 9dBμA/m in 10 meters distance.
- Type C - In this group, frequency of products falls in the range of 6.765 to 6.795MHz, 13.553 to 13.567MHz, and 26.957 to 27.283MHz. Magnetic field should not exceed 42dBμA/m in 10 meters distance.
- Type D - Frequency must be between 315 KHz and 30MHz, except equipment falling into any of the three categories mentioned above. Magnetic field strength must be as follows:
- 315kHz to 1MHz: -5dBμA/m in 10 meters distance
- 1MHz to 30MHz: -15dBμA/m in 10 meters distance
- Type E - This category is for equipment with a frequency between 40.66 and 40.70MHz, and a transmitting power of 10mW (e.r.p.).
- Type F - Equipment with frequency between 2400MHz and 2483.50MHz fall in this category. The transmitting power is same as above, that is, 10mW (e.r.p.).
- Type G - Frequency for these products is between 24.00 GHz and 24.25GHz with transmitting power of 20mW (e.r.p.).
If you require modular approval, keep in mind that different
regulations apply for full and limited non-independent operations.
For full modules, you must apply for SRRC certification separately. However,
the end product doesn’t have to be certified. The manual must clearly state if
the end product has not been certified.
For limited modules manufacturers may apply for separate SRRC, but end
products must also carry the certification. The latter will only require to
undergo emission testing for approval.
