NABL Testing Laboratory
Accredited by NABL (National Accreditation Board for Testing and Calibration Laboratories) in accordance with ISO/IEC 17025:2017 — Certificate TC-13547.
NABL-Accredited Facility · Certificate TC-13547
Our NABL-accredited laboratory anchors quality assurance for every component HEPL heat-treats, machines and fabricates. The same lab is available on a commercial basis to external manufacturers, fabricators and project owners who need independent, traceable certification — including on-site testing.
