 | CME demonstrates its testing laboratory accountability to
the public by maintaining Acccreditation at each of its
facilities. Each of CME's accredited labs has demonstrated
competence to a Nationally Recognized Organization (NRO)
of CME's operations, plant, equipment, personnel, and
quality systems. In order to stay accredited, each CME
lab must be routinely engaged in recognized Proficiency
Sampling Programs covering the accredited material tests
and must be routinely inspected by the NRO for compliance
to established Standards of the United States of America.
One of the most widely accepted Standards Organizations is
ASTM - American Society For Testing and Materials. Below
are links to some important industry NRO's and Standard
organizations:
