A third ballot was issued October 22, 2018, and closed on November 20, 2018. The revised edition of ANSI/NETA MTS was released in March 2019.
ANSI/NETA MTS contains specifications for suggested field tests and inspections to assess the suitability for continued service and reliability of electrical power equipment and systems. The purpose of these specifications is to assure that tested electrical equipment and systems are operational and within applicable standards and manufacturers’ tolerances, and that the equipment and systems are suitable for continued service. ANSI/NETA MTS-2019 revisions include online partial discharge survey for switchgear, frequency of power systems studies, frequency of maintenance matrix, and more. ANSI/NETA MTS-2019 is available for purchase in the NETA Bookstore at www.netaworld.org.
ANSI/NETA ECS, Standard for Electrical Commissioning of Electrical Power Equipment and Systems, 2015 Edition, was approved as an American National Standard on December 3, 2014. A project intent notification published in ANSI’s Standards Action on May 18, 2018, announced the intent to revise the standard. A 45-day public comment period began on April 26, 2019, and will close on June 10, 2019. An initial ballot was issued April 26, 2019, and will close on May 26, 2019.
ANSI/NETA ECS describes the systematic process of documenting and placing into service newly installed or retrofitted electrical power equipment and systems. This document shall be used in conjunction with the most recent edition of ANSI/NETA ATS, Standard for Acceptance Testing Specifications for Electrical Power Equipment and Systems. The individual electrical components shall be subjected to factory and field tests, as required, to validate the individual components. It is not the intent of these specifications to provide comprehensive details on the commissioning of mechanical equipment, mechanical instrumentation systems, and related components.
Voltage classes addressed include:
- Low-voltage systems (less than 1,000 volts)
- Medium-voltage systems (greater than 1,000 volts and less than 100,000 volts)
- High-voltage and extra-high-voltage systems (greater than 100 kV and less than 1,000 kV)
- ASHRAE, ANSI/NETA ATS, NECA, NFPA 70E, OSHA, GSA Building Commissioning Guide
The revised standard is scheduled for release in spring 2020. The 2015 Edition is available for purchase in the NETA Bookstore at www.netaworld.org.

ANSI/NETA ATS-2017, Standard for Acceptance Testing Specifications for Electrical Power Equipment and Systems is scheduled to complete an American National Standard revision process in late 2020/early 2021. A project intent notification was published in ANSI’s Standards Action on November 30, 2018.
ANSI/NETA ATS covers suggested field tests and inspections for assessing the suitability for initial energization of electrical power equipment and systems. The purpose of these specifications is to assure that tested electrical equipment and systems are operational, are within applicable standards and manufacturers’ tolerances, and are installed in accordance with design specifications.
This document is scheduled for release as a revised standard in the spring of 2021. Those interested in participating in the revision process should contact the NETA office for more information.
ANSI/NETA ETT, Standard for Certification of Electrical Testing Technicians, 2015 Edition, has been revised as an American National Standard. ANSI/NETA ETT-2018 was approved by ANSI as an American National Standard on February 22, 2018. The revised edition was released in March 2018. It is available now in the NETA Bookstore at www.netaworld.org, where a complimentary PDF copy can be downloaded or a printed copy ordered.
ANSI/NETA ETT establishes minimum requirements for qualifications, certification, training, and experience for the electrical testing technician. It provides criteria for documenting qualifications for certification and details the minimum qualifications for an independent and impartial certifying body to certify electrical testing technicians.
Comments and suggestions on any of the standards are always welcome and should be directed to NETA. To learn more about the NETA standards review and revision process, to purchase these standards, or to get involved, please visit www.netaworld.org or contact the NETA office at 888-300-6382.
