Test Time – upon receipt of test material, the corresponding times listed with the following procedures under GMW16705 will be followed:

  • Tensile Test
  • Staircase Fatigue Study
  • Overstress-Probe Fatigue Study
  • Strain-Controlled Fatigue Study


Thermomechanical Processing

Westmoreland Mechanical Testing & Research, Inc. provides Thermomechanical Analysis which studies the dimensional change of a material over a predefined temperature segment. A TMA applies a stress to a material and the resulting strain is measured while the material is subjected to a controlled temperature program.

TMA / SDTA 1 IC 600 and HT 1600

  • Combined temperature range of -112ºF to 3000ºF
  • Detects nanometer changes in length
  • Film Accessory Kit to allow for testing on thin films
  • Multiple probe types (3mm Flat, 1mm Flat, 3mm Ball Point, Knife Edge) for optimum results and resolution
  • General Testing: Coefficient of Linear Thermal Expansion, Glass Transition Determination, Softening Point, Heat Deflection Temperature, Determination of Material Anisotrophy)
  • Accreditations: NADCAP and A2LA
