SAR Evaluation Test

SAR TEST
SAR TEST

We offer testing services, based on the measuring method in accordance with Ministry of Internal Affairs and Communications Notification No. 628 dated October 10, 2001 of SAR -specific absorption rate in the human head- specified by law.

Applied to International Standard IEC 62209-2, the measuring method for SAR in human body except temporal part are regulated in Japan. We offer Body SAR test on the human body for the Radio equipment such as wireless LAN, mounted equipment and IoT equipment etc to be used near human body within 20 cm.

Also we are providing required test of radio equipment such as mobile phones those to be used near temporal within 20cm.

The normal usage means that manufacture or seller define in the instruction manual of product.

DFS Evaluation Test

We offer DFS test in accordance with Article 45 of Appendix to the Ministry of Internal Affairs and Communications Notification No. 88 in 2004.
Also we’re able to evaluate the DFS function in a shorter time by our unique DFS measurement system which adjust the detection rate in every radar pulse.

RF Conformity Test

It is mandatory to verify that the radio frequency of specified equipment are conformed with the Technical Standards to obtain Technical Standard Conformity Certification and Authorization of the specified radio equipment by the Radio Law. We offer characteristic tests based on the testing method specified in the regulation of Ministry of Internal Affairs and Communications Notification No.88 in 2004.

Telecom Conformity Test

It is mandatory to verify that the radio frequency of telecommunications terminal equipment are conformed with the Technical Standards to obtain Technical Standard Conformity Certification and Authorization by the Telecommunication Business Law.
We offer characteristic tests based on the testing method specified in the regulation of Ministry of Internal Affairs and Communications Notification No99 in 2004.

Applicable terminal equipment
  • Telephones to be connected to the equipment for analog telephones or mobile phones, private branch exchange equipment, button telephones, modems, facsimile equipment, and other terminal equipment that is separately notified by the Minister of Internal Affairs and Communications.
