Every test we run, explained with an animated schematic.
Ultrasonics to radiography, penetrant to phased array, cubes to CBR — how each method actually works, what it finds, and the standards behind it.
Why Metlab
Independence you can put your name to.
Since 1982, engineers have signed off structures, vessels and networks on the strength of Metlab results. That trust is built on three things:
Accredited to the standards that matter
INAB accreditation across laboratory testing (ISO/IEC 17025), welding procedure approvals (17020) and welder certification (17024) — plus State appointment as an RTPO under the Pressure Equipment Directive.
Multidiscipline depth, one provider
NDT, materials testing, welding certification, pressure inspection and CQA in one organisation — so the right method gets specified, not just the one on offer.
Four decades of showing up
Trading since 1982, backed since 2023 by the WH Scott Group — 190+ specialists managing 400,000+ statutory inspections a year.

How it works
From enquiry to certificate.
A defined route from question to defensible answer — however complex the asset.
01
Tell us the problem
Send the spec, drawing, standard or simply the question. A specialist — not a call centre — reviews it.
02
Method & quotation
We specify the right technique and standard, with a clear price and turnaround. No over-testing.
03
Test, inspect, examine
On your site or in our Cork and Dublin laboratories — by certified personnel under our accredited system.
04
Certificate & evidence
Results reported promptly, flagged immediately if something fails, and defensible in front of any auditor.
