Revisions to Certification Marking Requirements


Posted on March 19, 2019 at 10:13 AM


The Ministry of Internal Affairs and Communications (MIC) of Japan revises the technical standards for the Giteki certification marking.

Sample of the Giteki marking

R Mark - Radio Equipment Technical Standard Conformity Certification
T Mark - Terminal Equipment Technical Standard Conformity Certification

The goals of the revisions are as follows:

  1. Relaxation of the size requirement of certification mark.
  2. Allowing for radio equipment without displays to indicate the mark via an external display.

Revision of Certification Rule Format 7, Format 14 Note 1 as the following:

“Note 1 The size should be easily identifiable.”

There is no longer a minimum diameter requirement for the marking (previously 3 mm or greater).

Addition following rules to Certification Rule Article 8, 20, 27, 36, 41:

“An electromagnetic method that the display can immediately display the Certification Mark based on Format No. 7 in a clear state on the display of the product connected to the specified radio equipment that meets Technical Standard Conformity by a specific operation (Given that it can be displayed by wired connection with another product with built-in display before the operation of the specific wireless facility is first started)”

The device marking can be displayed on an external/peripheral monitor if the device has no built in display.

Due to the miniaturization and high integration of IoT devices, the indication of the mark of 3 mm on the modules etc. becomes difficult. In order to ensure the usability of IoT equipment etc., the mark should be easy to attach and recognize.
