In the customer day event held on 16 May 2025, DJID officially announced their plan to enforce mandatory of EMC immunity test for certain groups of devices such as switches, routers, etc. The EMC immunity test is performed based on the international standard of CISPR 35. The mandatory of EMC immunity test is implemented by considering the current capabilities of local labs for performing the EMC immunity CISPR 35. This step is part of the efforts of the Ministry of Communication and Digital to improve the safety and compatibility standards of telecommunications devices marketed and used in Indonesia.
In this article we will discuss all about new requirement of EMC immunity test and its affect to DJID certification process in Indonesia.
What is EMC immunity?
Electromagnetic compatibility or EMC test is the process of evaluating ability of telecommunication devices to function properly in the presence of electromagnetic fields and to ensure that it does not produce harmful electromagnetic emissions. EMC testing typically involves the two types of testing requirements below.
- EMC emissions test: it used to measure the amount of electromagnetic interference emitted by a telecommunication device.
- EMC immunity test: it used to measure the ability of telecommunication devices to continue their function properly even when exposed to electromagnetic interference from other devices or the environment.
The standard of CISPR 35 applies to multimedia equipment (MME) with a rated AC or DC supply voltage not exceeding 600 V. This standard applies to all types of multimedia equipment, including audio and video equipment, information technology equipment, and broadcasting equipment. The requirements in CISPR 35 cover a wide frequency range from 9 kHz to 400 GHz.
The immunity requirements outlined in CISPR 35 are designed to ensure that multimedia equipment can function properly even when exposed to electromagnetic interference that may be present in the environment. This interference can come from a variety of sources, including radio transmitters, power lines, and other electronic devices.
Current EMC requirement for DJID certification
Currently, the mandatory EMC test for DJID certification is only EMC emission test. The testing parameters for EMC emission test consist of EMC radiated emission and EMC conducted emission.
The EMC radiated emission is performed in the frequency range of 30 – 1000 MHz for low frequency and 1000 – 6000 MHz for high frequency. Meanwhile, the EMC conducted emission test is performed in the frequency range of 150 kHz – 30 MHz. The applicable international standard for EMC emission test used in DJID certification should be performed under CISPR 32.
If EMC immunity test will be mandatory, then an additional type of EMC test for DJID certification will be required soon. The number of testing parameters for EMC immunity is more than the EMC emission test. So, the price for doing EMC immunity will be higher than EMC emission test. The EMC immunity test used for DJID certification should be performed based on the international standard of CISPR 35.
Telecommunication devices mandatory to do EMC immunity test
The obligation of EMC immunity test does not apply to all types of telecommunication devices. EMC immunity test is planned to be mandatory for devices that fall under certain technical regulations only.
One of the regulations that will require EMC immunity test is technical regulation of KEPMEN KOMINFO No. 60 year 2022. This technical regulation is widely used for ethernet telecommunication network devices such as switch, router, and firewall. There are other several technical regulations that will also require EMC immunity test, including:
- Ethernet Telecommunication Network – KEPMEN KOMINFO No. 60 year 2022
- Wavelength Division Multiplexing – KEPMEN KOMINFO No. 6 year 2023
- Passive Optical Network – KEPMEN KOMINFO No. 58 year 2022
- Free Space Optic – KEPMEN KOMINFO No. 59 year 2022
- Modem Coaxial Cable Home Network – PERDIRJEN SDPPI No. 3 year 2021
- Integrated Services Digital Network – PERDIRJEN SDPPI No. 1 year 2020
- Single Sideband Power Line Carrier Terminal – PERDIRJEN SDPPI No. 8 year 2019
Local testing labs for EMC immunity test
Kindly note that the implementation of EMC immunity test has considered the capabilities of local testing labs in Indonesia. This consideration is in line with one of the clause in the technical regulation of KEPEMEN KOMINFO No. 6 year 2023 for wavelength division multiplexing devices.
Currently, there are already 3 local labs in Indonesia that are recognized for conducting EMC immunity test. This number has exceeded the minimum required of 2 labs if one new testing requirement is to be implemented. Those 3 local EMC labs include:
- BBPPT Lab
- HCT Indonesia Lab
- Qualis Indonesia Lab
EMC immunity test can also be conducted at DJID ‘s recognized foreign test labs and having EMC immunity testing scope.
Testing parameters for EMC immunity test
In total there are 7 testing parameters for EMC immunity test that need to be performed based on CISPR 35. EMC immunity test is to ensure that the telecommunication devices can resist the electromagnetic interference. The EMC immunity parameters include:
- Radiated immunity test
- Conducted immunity test
- Magnetic field testing
- Electrostatic discharge (ESD) test
- Electrical Fast Transient (EFT) test
- Surge test
- Voltage dip test
These EMC immunity parameters will also be adjusted to the condition of the telecommunication devices to be tested. For instance, if one telecommunications device does not have a magnetic field, then magnetic field testing is not mandatory.
When EMC immunity test comes into effect?
Based on the information during the customer day session, DJID plans to implement the obligation of EMC immunity test is on 1 July 2025. However, during the hearing process with DJID certification applicants, especially local companies that in charge with ethernet network telecommunications devices, most of them refused the given timeline from the authority.
This EMC immunity obligation can not be postponed for up to 1 year as a grace period considering that local labs are ready to conduct EMC immunity testing. Therefore, the possible timeline for the implementation of EMC immunity test is determined by considering the input from applicants which is more than 1 July 2025, but not to delay it for 1 year. The official date for the implementation of EMC immunity test will be published by DJID officially later.
