Usually, four issues can trigger the failure of the inspection, and potentially the refusal of the shipment by the purchaser:
1. Beyond the AQL limit
Based on the sampling plan, the inspector selects a predefined number of products at random. One by one being checked counts the number of defects, which are compared to the AQL limits, beyond the AQL limit
2. Non-compliance with local regulations
Missing country-specific labels & markings for specific products. The types of electrical safety testing required to depend on the type of product as well as the destination market. For example, the CE mark is recognized worldwide and indicates conformity with health, safety, and environmental protection standards for products sold within the European Economic Area (EEA).
3. Missing or Failing for Safety Testing
Electrical and electronic products must be tested to ensure they comply with a wide range of safety regulations before they can be certified and labeled. If the high voltage test, leakage current test, insulation resistance test, and ground continuity test are missed or failed, the importers will receive a failure report.
4. Quality Inconformity
The type and quantity not conforming to the order requirements result in a failure report to importers. Clients reject the goods or consult with the factory whether to accept the goods with concession.
The final random inspection aims to visual check on all the relevant aspects of the product: quantity, components, assembly, aesthetics, function, size, labeling, packaging, and other required parameters.
