Scratch & Mar

  • Scratch 5 Machine Multi-standard, programmable scratch and mar testing instrument. Meets ASTM D7027-05, ISO 19252‑12, ASTM D5178, TAMU/Avery-Dennison Mar, Ford 5‑finger, Erichsen cross-hatch, pencil-hardness (dead load), Volkswagon PV3952, GM 14688‑A‑10N.
  • Refurbished Scratch 3.5 & 4 Multi-standard, programmable scratch and mar testing instrument. Our refurbish program takes older equipment and refurbishes it to our strict laboratory standards. Most equipment meets the same or similar standards as The Scratch 5 Machine.

Impactors

  • Digital Izod/Charpy Impactor Multi-standard, variable-force, digital impact tester. This equipment can be configured as Izod, Charpy, or Double-Notch Charpy. It can reliably measure impacts to within 0.1% accuracy.

Peripherals

Imaging & Software

  • TAMU Black Box Low-albedo imaging system leveraging a digital camera and semi-specular light to optimize for mark visibility comparisons. The Black Box is best leveraged by making use of our analytical software, Tribometrics.
  • Basic Imaging System Our affordable imaging system, based on a flat-bed scanner and color correction calibration, this system makes use of our Tribometrics software to reliably measure and compare scratches.
  • Tribometrics This is our industry-leading software analysis and assessment solution. It leverages artificial intelligence routines mimicking the biological visual processes of humans, and is matched to panels of human observers. This software can be used to accurately order the comparative performance of scratch and mar as assessed by an idealized human observer.

Scratch & Mar

  • Thin Film/Pneumatic Chuck A specialized pneumatic chuck that can hold films and thin films steady for testing. This system uses sacrificial backing plates that can be interchanged to mimic the substrate common to each film. This option can also be combined with our hot plate.
  • Temperature Control (Hot Plate) This plate will heat and hold sample temperatures up to 150° C.
  • Turn Table This plate is used in conjunction with cross-hatch testing to help improve the testing speed and reliability of these types of tests.

Impactor

  • Impactor Notcher Configurable as either Charpy or Double-Notch Charpy, this notcher helps you produce accurate notches in samples.

Options

Scratch & Mar

  • Field Indexing (Y-Axis) Manual or automatic Y-Axis control for the machine to assist with indexing over test samples.
  • Puncture Detection Used in conjunction with the film chuck, this option allows the equipment to detect and mark the location of film puncture.
  • Reciprocation/Wear This option is used when reciprocation or wear testing is required for performance analysis. It can be combined with puncture detection on films.
  • Alternative Styli Geometry We carry stainless and carbide ball tips in 1mm, 2mm, 3mm, 5mm, 7mm, and 10mm; tilting/mar tips in 12mm & 6mm barrel; 5x5mm and 7x7mm abrasive tips; ASTM D5178 loop styli chucks.

Impactors

  • Impactor Anvil An alternative impactor anvil that allows you to convert between Izod or Charpy impact testing.
  • Impactor Mass Additional masses used to increase the force applied during testing.
