As discussed earlier, in South Korea, local testing is a mandatory requirement for obtaining KC certification. Therefore, there are sample requirements for South Korea type approval that all manufacturers wishing to market their products in the country must understand.
Sample requirements for South Korea type approval are necessary to ensure that telecommunications equipment to be sold and distributed meets the specified criteria. These requirements are established by the Radio Research Agency (RRA), which regulates all certification requirements.
The criteria and number of samples requirements for South Korea type approval are crucial for the smooth progress of the certification process. To learn more, please read this article.

What is a Testing Sample?
Every type approval certification testing process requires the submission of test samples. The devices will later be used to measure against predetermined standards.
For countries that require local testing, submitting samples is mandatory. The number and type of samples required will depend on the device’s features and the testing methods.
Local testing for South Korea type approval is mandatory. Therefore, sample requirements for South Korea type approval are necessary. We will discuss the number and requirements in another section.
Testing Process
The sample requirements for South Korea type approval will be used to conduct several types of testing. The product features and the technical regulations governing them will determine the types of testing required.
The following types of testing must be conducted:
- Radio Frequency (RF) Testing: This process is performed on devices that use radio frequencies to evaluate wireless signal transmission.
- Electromagnetic Compatibility (EMC) Testing: A testing process for devices to ensure they do not interfere with other devices.
- Specific Absorption Rate (SAR): The process of evaluating RF energy exposure to humans.
All processes will be conducted at local laboratories in South Korea. The Certification Body (CB) will determine the testing location based on each laboratory’s capabilities and availability.
It should be noted that local testing may be conducted at more than one laboratory. This is because each laboratory has different capabilities and availability.
Sample Requirements for South Korea Type Approval
Sample requirements for South Korea type approval refer to mandatory testing requirements. In these sample requirements, the number and type of samples are critical for testing.
The number and type of samples will vary depending on the device’s features and testing requirements.
Sample Types
Generally, a sample is required for each test under the South Korean type approval process. Two mandatory tests must be conducted: RF and EMC.
Meanwhile, SAR testing is required for specific products that are typically used near the body during normal operation.
Therefore, you will need at least two test samples. If your device requires SAR testing, you will need to submit three samples.
Conducted samples are used for RF testing. Standard samples are used for EMC testing. Meanwhile, radiated samples are used for SAR testing.
1. Conducted sample
A conducted sample is a sample that has been modified or equipped with an RF cable or SMA connector. The cable and connector are used to measure frequency range, output power, bandwidth, and spurious emissions.
2. Normal sample
A normal sample is an unmodified sample that must be identical to the product intended for marketing and use. Testing of standard samples must comply with applicable international standards, such as Conformité Européenne (CE) or the Federal Communications Commission (FCC).
3. Radiated sample
A radiated sample is a sample that directly emits radio frequencies when powered on. This sample is required for low-power products with a transmission power of less than 10 mW.
Pre-Testing Helps Ensure the Sample Complies
Sample requirements for South Korea type approval are critical. Progressing through the certification process to the stage of submitting documents for evaluation depends on testing.
Failure in testing will delay your certification process. You may even incur costs for recertification.
Partnering with Dimulti will help ensure that your device complies with applicable technical standards. We offer pre-testing services that many other certification providers do not.
We test your samples in our in-house laboratory before submitting them for official testing in South Korea. Pre-testing is conducted for RF testing. The parameters examined include frequency range, output power, and bandwidth parameters.
For bandwidth testing, our equipment supports frequencies ranging from 125 kHz to 8 GHz. Frequencies outside this range must be tested directly at an official laboratory.
Pre-testing detects issues early on, so any errors can be corrected immediately. This ensures there will be no further failures during official testing.
Pre-testing services are already included in our package, so you don’t need to worry about additional costs. Where else can you get a service of this caliber without incurring significant expenses?
