Meaning
Independent technical institutions authorised by national regulatory authorities perform compliance testing on electronic and telecommunications equipment before market entry. Such a designated testing laboratory evaluates hardware against established standards to verify electromagnetic compatibility and radio frequency emissions. The boundary of this function ends where actual certification is granted, as the laboratory holds authority to test but does not issue the final regulatory seal.
Manufacturers rely on these institutions to validate their designs prior to mass production.
Accreditation Criteria
National standards govern the formal recognition of these facilities. To operate, a designated testing laboratory must maintain accreditation under ISO IEC 17025 to prove its calibration accuracy and testing repeatability. This status requires annual audits by appointed bodies to verify that the equipment remains calibrated and the personnel are qualified.
Evaluation Scope
Testing activities inside these facilities focus on physical measurements of radio signals. Technicians in a designated testing laboratory measure spurious emissions and power limits under varying temperature conditions. These evaluations ensure the device does not interfere with critical public safety frequencies.
Certification Influence
Regulatory approval files depend directly on the reports generated during these sessions. When a manufacturer submits the output from a designated testing laboratory, the certification body accepts the data as legally binding evidence of compliance. This relationship ensures a clear division of labour between the testing entity and the issuing authority.
