Machining Test Specimens
Tensile Specimen, Charpy Specimen & More Machined to Order
When test specimens are needed for mechanical or corrosion testing, let our machinists do the work. The latest CNC equipment for milling, turning and grinding allows us to prepare the highest quality test specimens quickly and economically, including a round or flat tensile specimen, charpy specimen with a V-notch, impact test specimen and many others for jominy, stress rupture, fracture toughness and more testing. The LTI Machine Shop prepares all test specimens according to ASTM standards (ASTM A370, ASTM E8, ASTM E23) and the requirements of our customers. All test specimen machining is Nadcap accredited.
Laboratory Testing Inc. is a NIST Qualified Manufacturer for Charpy V-notch Impact verification test specimens. Traceability of sample material and test specimens is insured from receipt inspection through the final process in our laboratory machine shop.
Test specimen machining is a time-saving convenience for our testing customers because the complete order can be processed right at LTI, from receipt of the sample to preparation of the Certified Test Report. Laboratory Testing also provides test specimens to companies that perform their own testing inhouse.
Refer to our Sample Size Requirements under the Guidelines section on our Resources page when ordering testing services that require test specimens.
