Mechanical Testing

Don’t Just Say It’s Strong: Let Us Prove It

Mechanical testing hardnessMechanical testing provides information about the suitability of a material for its intended application by evaluating mechanical properties. Test results help companies design and manufacture reliable products that will perform as expected.

Laboratory Testing Inc. has a full-service mechanical testing laboratory near Philadelphia, PA (USA) that routinely performs tensile testing, charpy impact testing, hardness testing, fracture toughness and fatigue testing, stress rupture and creep testing, and more. We also have furnaces to provide capability heat treating and testing to confirm upgrade to specification or your requirements.

LTI Advantages

Our combination of technical expertise, competitive pricing and fast turnaround provides an ideal solution for your testing needs. Qualifications will also meet your requirements:

  • PRI Nadcap and A2LA accreditation
  • Testing completed according to ASTM, EN, ISO, MIL, NASM industry standards and specifications
  • PED approval based on ISO 17025 certification
  • Mechanical and materials engineers to help with unique needs and questions
  • Specimen preparation for all mechanical tests

Customers receive a Certified Test Report showing the complete results of each mechanical test.

Mechanical Properties

Mechanical testing services measure materials under various temperature, tension and compression conditions. The test results provide customers with important information about the mechanical properties and characteristics of their materials:

  • Strength
  • Hardness
  • Ductility
  • Impact resistance
  • Fracture toughness
  • Elongation
  • Stress

Mechanical Test Ranges

  • elevated temperature tensile testTensile testing of metal parts and specimens in all sizes, from the smallest fasteners to huge tubing and bolts on our 600,000 lb. capacity machines. A 10,000 lb. capacity tensile machine provides plastics testing
  • Elevated temperature tensile testing using a furnace carousel to process up to three samples at once. Samples can be heated to 1800°F
  • Stress rupture and creep testing comply with ASTM standards and can be performed at temperatures up to 2000°F
  • Fracture mechanics equipment can generate up to 100,000 lbf. and controls the test temperature between -150°F and +2000°F
  • Rockwell, Brinell & Superficial hardness testing is available for metals, while a Shore Durometer hardness tester provides plastics testing
  • Charpy impact testing is performed from -452°F to 500°F
  • Welder & Procedure Qualification: (per MIL & API specifications, ASME & AWS codes, ASTM & EN standards and the Pressure Equipment Directive)

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 from metals and many plastics for all types of mechanical testing. 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.
