About HTW Lab:
To support your EMI testing journey, HTW Lab has come up with an EMI Pre-Compliance Testing Solution. Talk to our expert to get an EMI Testing solution for your IoT Devices, ZigBee Devices, WLAN Devices etc. Perform a quick EMI pre-compliance test of your wireless device and have the confidence that you’ll pass final EMI Compliance Testing.
Communicate with our experts to determine your needs and we will provide you with a free evaluation and proposal.
The Electromagnetic compatibility (EMC), Electromagnetic Interference (EMI) pre-compliance and debugging tests, when started early, can greatly reduce the cost of EMC & EMI management. The Electromagnetic compatibility (EMC) and Electromagnetic Interference (EMI) pre-compliance testing in your hardware development process can help you avoid costly and time-consuming redesigns after EMC compliance testing failure.
Why should you perform the pre-certification testing and then witnessed final testing on your product?
The answer is that it actually saves you time and money. If your product is tested directly by an agency and fails to comply, it will be sent back to you to retrofit for compliance. When you are ready to resubmit for ‘another try,’ you will potentially be at the end of a 4-8 week waiting queue. Such a process is very time consuming, depending on the types of design challenges that you are facing. Although you may pay extra for pre-certification testing, you gain the ability to see and fix problems before your product is evaluated by an agency witness. We can also provide consulting services to assist you in the process of finding feasible, cost effective solutions to your certification challenges, prior to final, agency witnessed testing.
Pre-compliance testing dramatically improves a device’s chance of passing EMC testing and significantly lowers the risk of failure during the certification process. Failing an EMC test poses a substantial threat to project deadlines and budget – something no company wants to go through. All wireless devices or consumer electronics can be pre-tested in the research and development stage before starting small-scale/large-scale production and formal testing and certification. In addition, local testing is mandatory for wireless device testing and certification, but the prototype has only 1-2 retest opportunities in some countries.
During product testing and certification, the best way to avoid detecting EMC problems far too late is to include EMC in early design reviews, actively search for interference-causing emissions on the PCB or component level during EMI debugging, followed by pre-compliance testing on the assembled product.

1. Provide us with product pictures, product brochures/manuals
2. Determine your needs（test report purpose/ test itmes/ standards）
3. Receive the testing/compliance service proposal and quotation
4. Sign contract and make payment
5.Send samples (please contact us for address info.)
6.Informed project opening and test TAT(turn around time) via email
8.Draft report for your confirmation
9. Formal reports endorsed by ILAC - CNAS (electronic version)
10.Sample Discard or Return
A pre-compliance test can be easily adapted to individual requirements since it is not bound by any rules, enabling fast and cost efficient measurements. In some cases, fast testing is key, in others maximum accuracy and reliability are needed. Test environments differ greatly depending on whether conducted or radiated interference is measured. Also, our experienced technician team is able to offer debugging services. We offer competitive prices and charge the pre-compliance testing and debugging services separately. For more information, please don’t hesitate to contact us! Email us at firstname.lastname@example.org.
The samples should be provided safely with standard shipping status. Please provide the samples with sterile barrier packaging if the product is planned to sell under sterile conditions. Have a question about product testing and certification? Email us at email@example.com. If possible, kindly tell us ‘how did you hear about us’.
