What is the APEC-TEL MRA?
The APEC-TEL Mutual Recognition Arrangement (MRA) is a multilateral arrangement between economies in the APEC region. The APEC TEL MRA for Conformity Assessment of Telecommunications Equipment, which came into effect on 1 July 1999, facilitates the recognition of each other’s conformity assessment results.
An Uninterruptible Power System is usually used to protect telecommunication or other electrical equipment where an unexpected power disruption has occurred. It will store energy to supply the power when needed.
The National Institute of Standards and Technology (NIST) reports that even though the UPS product was already covered under the original APEC TEL MRA, exchange letters between the US and the Chinese Taipei BSMI have aided the agreement to expand Annex 1 to include CNS 14757-2 (2010). Much effort went into this acceptance process.
Per the Chinese Taipei BSMI, EMC testing Labs must demonstrate that they have been Accredited to ISO/IEC 17025 to conduct tests to the appropriate CNS standard by an accreditation body acceptable to NIST.
In addition, EMC Testing must be performed in accordance with the following National Standards of the Republic of China:
1. CNS 13438 – 2006 – Up to 6 GHz. The measurement distance for frequencies from 1 GHz up to 6 GHz is 3 meters. CABS that do not have the necessary facilities to test radiated emissions up to 6 GHz can apply for a limited designation as follows: CNS 13438 – Up to 1 GHz. The measurement distance for frequency up to 1 GHz is 10 m.
2. CNS 14757-2 (2010) – Uninterruptible Power Systems (UPS) Part 2: Electromagnetic compatibility requirements (added December 1, 2016)
The need for efficient standard development in the telecommunication field is at an all time high. What would happen if the UPS your family depended on to power your smart home failed to produce power as intended? Appreciate the Standards that keep the ball rolling.
