Attachment D - Equipment and Test Matrix - REV19

ATTACHMENT D | EQUIPMENT AND TEST MATRIX

Electrical Distribution System Inspection, Testing, Maintenance, Calibration, and Infrared Scanning. Atlanta VA Health Care System (Station 508). Revision 19, August 25, 2026. This matrix defines the required level of work by equipment class and applies to the equipment listed in Attachments A, B, and C. Where a class is not present at a site, its row does not apply. Test methods follow ANSI/NETA MTS in the edition adopted by the VA and the authority having jurisdiction as of the solicitation date, and the manufacturers' instructions. This attachment governs test method only to the extent it is consistent with the Statement of Work; it does not add an asset, add a quantity, or expand the base scope (Statement of Work, Section 3.1). Equipment class
