Mechanical Testing
Don’t Just Say It’s Strong: Let Us Prove It
Mechanical testing services measure the strength, hardness and ductility of materials under various temperature, tension, compression or load conditions. Mechanical testing provides information about the suitability of a material for its intended application to help companies design products that will perform as expected.
Laboratory Testing Inc. offers a full-range of mechanical testing services including tensile testing, impact testing, hardness testing, fracture toughness testing and stress rupture testing to provide customers with important information about the mechanical properties and characteristics of their materials.
Mechanical Testing Equipment Capabilities
- Our tensile testing equipment can handle metal parts and specimens of all sizes, from the smallest fasteners to huge tubing and bolts on our 400,000 lb. capacity machines. A 10,000 lb. capacity tensile machine provides plastics testing
- Elevated temperature tensile testing using an elevated temperature furnace carousel to process three samples at once. Samples can be heated to 1800°F
- Stress rupture testing at LTI complies with ASTM standards and is performed at temperatures up to 1850°F
- Computerized fracture toughness testing equipment can generate 55,000 lbs. of tensile or compressive force and is used in conjunction with an environmental chamber that controls the test temperature between -150°F and +350°F
- Rockwell, Brinell & Superficial hardness testing machines are available for metals; a Shore Durometer hardness tester provides plastics testing
- Charpy impact testing is performed from -452°F to 500°F
Test Specimens for Mechanical Testing
For convenience and quick turnaround, LTI’s full-service Machine Shop is fully staffed on two work shifts to prepare specimens for all types of mechanical testing from metals and many plastics. Test specimens are machined according to ASTM standards A370, E8, E23 and customer specifications, and LTI is PRI/Nadcap accredited for specimen preparation. LTI is also on NIST’s (National Institute of Standards and Technology) Qualified Manufacturers List for Charpy V-notch Impact verification specimens. Heat treating capabilities are also provided.
