As electronic devices have become increasingly common, people now handle electrical products in their everyday lives.
To protect users’ lives, health, and property, many countries have established product safety standards. Certification bodies evaluate products based on these standards to ensure they meet required safety levels.
Safety standards assess products from multiple perspectives, including insulation, grounding, construction, temperature, materials, labeling, and tests under abnormal conditions. When manufacturing or selling electrical products, it is essential to comply with the relevant national safety standards and obtain the appropriate certifications.
Certification bodies also conduct periodic factory inspections to verify that certified products continue to be manufactured in accordance with the procedures established at the time of certification. These inspections help prevent potential hazards before they occur.

In the IT/AV equipment field—where switching power supplies are widely used—national standards have now been harmonized with the international standard IEC 62368‑1. Most of our switching power supplies, with some exceptions, have obtained safety certifications, allowing customers to use them with confidence.
When seeking safety certification for a complete system, manufacturers can often streamline the process by simply including the certification number of the power supply in the final product’s application documents.

Below are examples of major safety standards used in various countries and regions.
