MET Laboratories tests and certifies watthour meters to meet requirements in the United States, Canada and elsewhere. MET tests ANSI C12 and Canadian LMB-EG-07 for accuracy, UL 61010 and CSA 22.2 No. 61010.1 for Safety and NEMA 250 for enclosures. We also test and certify compliance for FCC and Industry Canada on electronic meters for EMC.

MET is the first organization to receive recognition from Measurement Canada to test previously approved electricity meters which have been modified and require re-certification. The scope of this recognition consists of electricity meters for Measurement Canada's approval process, as required by LMB-EG-07, Specifications for Approval of Type of Electricity Meters, Instrument Transformers and Auxiliary Devices" This recognition became effective September 12, 2007.

MET is accredited as a Nationally Recognized Testing Laboratory (NRTL) to meet requirements of local authorities and accredited as a meter laboratory for accuracy certification.

Our watthour meter certification program is widely accepted in North America and throughout the world.

MET's certification program includes radio frequency (RF), wireless enabled metering systems. Advanced Metering Infrastructure (AMI) technology allows remote meter reading with wireless Automated Meter Reading (AMR) modules, allowing multiple utility meters or submeters to be read by a single host meter.

MET Laboratories' certification provides confidence that the installation of wireless devices does not adversely affect the accuracy of the meter under any environmental or fluctuating voltage conditions. Additionally, the certification assures that the meter continues to comply with the ANSI C12 requirements after the installation of the RF device(s).

MET is an A2LA* accredited certification body and is an accredited RF test facility for US, Canadian, and international wireless standards. MET has a new modular impulse generator that increases our surge capabilities from 208VAC, 16A to 480VAC, 25A. This meets EN 61000-4-5 requirements that became mandatory in 2007. Additionally, this upgrade will satisfy surge withstand capability requirements of:

• ANSI C37.90.1:1989 IEEE standard surge withstand capability (SWC) tests for protective relays and relay systems AND
  
• IEEE C37.90.1:2002 IEEE standard for surge withstand capability (SWC) Tests for relays and relay systems associated with electric power apparatus (now required)
