MET Laboratories was founded by Leonard Frier as Maryland Electrical Testing in 1959. As the customer base quickly expanded beyond Maryland, the name was changed to MET Electrical Testing Company.
Originally, the company focused on testing high voltage electrical transmission and distribution systems.
In the 1970's, MET was among the first laboratories to perform EMI and telecommunications testing to the emerging FCC regulations.
In 1989, MET became the first Nationally Recognized Testing Laboratory (NRTL) in the United States for testing and certifying products to UL safety standards.
In 1992, MET changed its focus exclusively to testing and certification of electrical products - whether in the laboratory or at customer locations. Consequently, the name changed to the present MET Laboratories.
Also in 1992, the MET test report became accepted in 30 countries through the IECEE Certified Body (CB) Scheme.
MET has been a pioneer in testing and certification services and continues to be in the forefront of the electrical standards industry.
