This program is operated based on ISO/IEC 17011. In this standard which
is international criteria for accreditation body, an accreditation of
testing laboratories is required to evaluate whether the laboratory conforms

JNLA was internationally accepted to have been operated based on these

Laboratory Accreditation Cooperation) /MRA (Mutual Recognition Arrangement)
