What Are Our Test/Homologation Services ?
Our testing services have been commissioned to conduct a number of different development tests with a focus on commercial vehicles (trucks and buses). As a result, in addition to vehicle testing, we have a great deal of experience in various homologation tests and witnessed tests. Based on this technology, we offer a homologation testing service that complies with safety standards and agreement regulations. Please refer to the following list of test items for details.
Vehicles (motor vehicles, motorized bicycles, and light road vehicles) operating in Japan are regulated by the “Road Transport Vehicles Act” of the Ministry of Land, Infrastructure, Transport and Tourism. The Road Transport Vehicles Act stipulates “Security Standards“ as well as various requirements for the design and manufacture of automobiles to ensure safety and prevent pollution. Japan, which agreed to the UN's “1958 Agreemet“ in 1998, has continued to gradually adopt the agreed upon regulations.
