An electronics inspection combines safety tests, a full function test and a cosmetic check on a random sample drawn to ANSI/ASQ Z1.4. Here is what our inspectors check on consumer electronics and electrical products.
Small appliances, chargers and power supplies, lighting, audio, wearables, battery-powered devices and accessories.
Each defect in the sample is photographed and counted in its class. Your AQL plan sets how many are allowed; for critical defects the answer is none.
Likely to injure the user or breaks a mandatory rule of the destination market. One critical defect in the sample means the lot is not accepted.
Likely to cause a failure, reduce usability or make the product unsaleable, so a customer would return it.
A departure from the specification that does not affect use and is unlikely on its own to cause a return.
Your specification and approved sample decide the final class. Where a buyer defines zones (for example, zone A for the most visible surfaces), a defect in zone A is usually classed higher than the same defect in a hidden area.
Dielectric strength at the voltage and time of the product standard (e.g. IEC 60335-1 or IEC 62368-1).
Resistance between the earth pin and exposed metal on Class I products.
Power and current at rated voltage against the rating label.
Every button, mode, indicator and display, plus charging and pairing.
One unit opened: wiring, soldering, insulation and key components against the approved construction.
Strain relief holds the cord under a firm pull.
| Point | How we measure |
|---|---|
| Overall length, width, height | Calipers against the specification |
| Cable length | Plug to product, in metres |
| Plug pin dimensions | Where the plug is part of the product |
| Button travel and fit | Against the golden sample |
| Weight | Scale, in grams |
Unit: mm unless stated. We measure at least five units per size or version against your specification and tolerances, and report every reading.
We check marks and documents against your specification. Your compliance team or test lab confirms which rules apply to your exact product.
We bring calibrated hi-pot and earth testers, run the safety tests first, then the full function test, then the cosmetic check. One unit is opened and compared with the approved construction so component changes are caught early.
Suggested planLevel II with AQL 0 / 2.5 / 4.0 is common. Safety tests often run on every sampled unit or a special-level plan.
Anything else, ask us directly. A principal replies, not a bot.
[email protected]Hi-pot (dielectric strength), earth continuity on Class I products, input power at rated voltage and a cord pull check, using calibrated equipment. Full certification testing is done by an accredited lab.
Yes, usually one unit. We compare the wiring, soldering, insulation and key components with the approved construction or the certified sample, so any component change is caught before shipment.
Anything that could cause a shock, fire or injury: a hi-pot or earth continuity failure, exposed live parts, damaged insulation, a wrong plug or a swollen battery. One critical defect means the lot is not accepted.
Tell us the product, the factory and the date. We confirm the inspector and the fixed price the same working day.
