Specializing on Automotive
Our Company's Japan National Laboratory accredited laboratory specializing on automotive sectors will start a new testing beginning with EMC measurements （CISPR 25） plus safety tests and design support.
At our new EMI site, we address evaluation items such as wideband noise, narrowband noise and safeguard of broadcasting businesses employing the antenna method, TEM cell method, BCI method, etc.
Effective April 2008, we will also commence R&TTE technical compatibility test services.
- Note 1:
Effective since 1999, the R&TTE directive targets wireless and telecommunications equipment in Europe.
R&TTE: Radio Equipment and Telecommunications Terminal Equipment

Electromagnetic Interference Measurement for the Protection of Automotive Receiver Equipment （CISPR 25） *Note 2
Measurement of interfering radiation （EMI） emitted by electrical equipment, while wideband and narrowband emission measurements are possible up to Class 5
EMI （Electromagnetic Interference） is an efficient evaluation to restrict electromagnetic interference radiation and propagation generated by electrical equipment jamming other electrical equipment with electromagnetic noise （electric waves） conduction.
RF Immunity Examination （ISO11452-2）
An ISO11452-2 compliant continuous radiation electromagnetic field examination system.
It performs irradiation tests for electric & electronic automotive components （ESA） and wireless harness （1.5m） and measures the extend of malfunction and strength of immunity.
TEM Cell Examination （ISO11452-3）
ISO11452-3 compliant TEM cell examinations.
It performs irradiation tests for electric & electronic automotive components （ESA） and wireless harness and measures the extend of malfunction and strength of immunity while exposure of 200V/m are possible for 10kHz to 400MHz range.
Immunity examination of electrical goods by exposure to electromagnetic fields （ISO11452-4）
An ISO11452-4 compliant bulk current injection examination.
By injecting RF current into the power and signal lines etc. of the harness by means of a bulk current injection （BCI） probe we measure the extend of malfunction and strength of immunity.
It is possible to impress 200mA current with closed-loop method or anagram between 1 MHz to 2GHz.
Electromagnetic interference and immunity test for automotive on-board equipment （ISO7637）
Conforming to ISO7637-2, excessive voltage phanemena generated by automotive equipment noise and power cuts are typically measured as shown.
Excessive voltage resistance and excessive voltage phenomena examination services will be launched in April 2008.
Automotive Service Standards （CISPR 25 compliant Electromagnetic Darkroom）
- Note 2:
Among various standards of the Comité International Spécial des Perturbations Radioeléctriques International, CISPR, （Special Committee on Radio Interference）, the CISPR 25 standard recommends limitation of radio interference and measurements methods for the protection of receivers used on motor vehicles. Its objective is protection of on-vehicle receivers against conduction and emissive interference waves emitted from electrical/electronical components used on-board or in large equipment.
