Standards
Our NABL-accredited laboratory (Certificate TC-16263) is assessed to perform the tests listed below, each against a named clause of a recognised standard. Separately, our products carry third-party certificates confirming they have been tested and found compliant. The first tells you what we can test on your part; the second tells you what our products have already proven.

What we can show
ASTM B117
Salt spray results are only comparable when the apparatus and the method are both named, which is what ASTM B117 fixes. Our chamber is accredited for coated products and for plated products as two separate scope entries, so a plated fitting and a painted bracket are both in scope rather than one being run by analogy with the other. What the result is reported against. The class in ASTM B840, or whatever your specification names. Is settled at enquiry rather than after the run.
ASTM B117: Accredited scope, certificate TC-16263
Listed twice on the NABL scope annexure. Once for coated and once for plated products.
ASTM B117. Reported against your classification
ASTM B840 classes where the specification uses them; state the class at enquiry.
ASTM A262
An austenitic stainless steel can meet its chemistry certificate exactly and still fail in service, because sensitisation is a change in where the chromium is rather than in how much of it there is. Held too long in the wrong temperature band. By a weld, or by a heat treatment. Chromium carbides precipitate at the grain boundaries and the metal beside them is left depleted. ASTM A262 is the method that finds it, and it is the one to specify when a stainless part has been welded and will see a corrosive duty.
ASTM A262: Accredited scope, certificate TC-16263
Listed under mechanical, metallography test.
ASTM A262. Runs alongside composition testing
Chemistry for austenitic stainless to ASTM E1086 and IS 9879 is on the same accredited scope.
