Applicable Standards

Electrical Appliance and Material Safety Law

The Electrical Appliance and Material Safety Law is intended to regulate the manufacture, sale and marketing of any electrical appliance in Japan and promote voluntary activities of private businesses to secure the safety of their electrical appliances, thereby preventing hazards and injuries that may otherwise occur due to imperfection in the safety of such appliances.

To achieve the above goal, the nation has established engineering standards to check products for compliance with the standards to qualify the products for use of such marks as listed at right if they are certified to have complied with the standards, while prohibiting the sale or use of any product marked with any such mark.
