Numbers you can defend.

Every result with its uncertainty, its method, and who touched it.An accredited testing lab for people who will have to stand behind a number in a room full of people who'd rather it were different.

results issued without an uncertainty. A number without a width isn't one.

A number you can take into a room.

Regulator, insurer, court, customer. When the result is challenged, the report answers by itself: method, calibration, replicates, custody, signatures. We're rarely called. That's the point.

Tests

Three things we test most.

The full scope is on the accreditation schedule, forty-one methods long. These are the three that fill the bench.

Mechanical · metals, polymersTensile & hardness

SampleCoupon or part

Yield, tensile, elongation, Brinell. The numbers on the mill cert, checked.

Defensible

What makes a number defensible.

Five things on every report. Miss one and it's an opinion.

Method, by numberThe standard, the version, and any deviation from it. Written down, not implied.

Uncertainty, expandedThe ± with its coverage factor. k = 2, 95%. Every result. No exceptions for tidy numbers.

Calibration, traceableEvery instrument in the chain, back to a national standard, with dates.

Custody, unbrokenWho received it, who opened it, who tested it, who signed it. With times.

Replicates, shownNot just the mean. The spread. If it's wide, we say so, and we say why.
