Watson Coatings Lab

HOUSTON – The Watson Coatings Laboratory, a division of Watson Grinding & Manufacturing announces its A2LA Accreditation ISO 17025:2005.

A2LA Accreditation ISO 17025:2005 is used by testing and calibration laboratories that produce testing and calibration results. The standard is specific in requirements for competence. Accreditation is a formal recognition of a demonstration of that competence. A prerequisite for a laboratory to become accredited is to have a documented quality management system. Laboratories use A2LA Accreditation ISO 17025:2005 to implement a quality system aimed at improving their ability to consistently produce valid results.

In recognition of the successful completion of the A2LA evaluation process, accreditation is granted to this laboratory to perform the following tests on metal powders and thermal spray coatings:
