Our own standardized lab handles pre-testing, rectification and re-testing; officially designated labs handle formal type tests and network access testing — walking on two legs, catching problems early so submissions don't come back.
Most certifications stall at the same point: metrics only fail after the samples are submitted, then it's rework, reship and queue for re-testing — a whole round lost to logistics. We do pre-testing and rectification in our own lab: over-limit metrics are located on the spot, fixed the same day, re-tested right after. Formal type tests and network access testing still produce reports from officially designated or authorized labs, while we handle matching, scheduling and on-site follow-up.

Common test items and typical timelines by product and certification type.
| Testing field | Certification | Typical test items | Standard timeline |
|---|---|---|---|
| Electrical & electronic safety | CCC | Temperature rise, dielectric strength, insulation, mechanical strength, construction check | 3–5 weeks |
| EMC | CCC / SRRC | Conducted disturbance, radiated disturbance, ESD, surge, radiated immunity | 2–4 weeks |
| Wireless RF | SRRC | Transmit power, frequency range, occupied bandwidth, spurious emissions | 3–6 weeks |
| Telecom terminal interfaces | Network Access License | Network protocol conformance, interface performance, interoperability testing | 5–6 weeks |
| Environmental reliability | General / customer-specified | High/low temperature, damp heat, vibration, drop, salt spray | 2–4 weeks |
| Battery & materials | CCC supporting tests | Battery safety (GB 31241), UN 38.3 transport assessment, material composition | 3–6 weeks |
