Radio Frequency Testing

Practical Insight：A manufacturer of portable Bluetooth speakers chose to run BSMI and NCC testing in parallel at a single lab. By locking the firmware version before submission and using the same sample batch for both tests, the company completed the entire dual certification in approximately 6 weeks—compared to an estimated 10 weeks if done sequentially. The key was selecting a lab capable of both BSMI and NCC testing under one roof.

Q1　Can I apply for BSMI and NCC certification simultaneously?

Yes. The two certifications are administered by separate agencies and do not depend on each other. Submitting samples for both tests at the same time is the fastest route to full compliance.

Q2　What happens if my product fails BSMI or NCC testing?

You will need to address the failure, modify the product, and resubmit samples. This adds re-test costs and extends the timeline by approximately 2-4 weeks per iteration. Pre-compliance testing before formal submission significantly reduces this risk.

Q3　How does series certification reduce cost?

If multiple models share the same core circuit and RF module and differ only in color, housing, or non-safety components, you can certify one primary model with full testing and add derivative models through a simplified evaluation—reducing both cost and time per additional model.

Q4　Does the BSMI certificate expire?

BSMI verification registration is valid for 3 years. NCC type approval does not have a fixed expiration but may require re-application if the product undergoes significant design changes. Plan for renewal timelines when scheduling production runs.

Q5　What is the most cost-effective approach?

(1) Run pre-compliance screening during development; (2) Lock firmware before submitting samples; (3) Choose a single lab for both BSMI and NCC; (4) Apply for both certifications in parallel; (5) Use series certification for multiple models.
