Testing Lab

Product Testing Services at Rudolph Bros. & Co.



We have partnered with one of the finest testing laboratories in the United States to offer standardized testing for our customers or potential new customers.

Examples of the test capabilities would include many ASTM standards for tensile, compressive, shear, fatigue, flexural, peel, and impact strength.

Our lab is an internationally recognized leader in the composite material testing field, and their accreditation and approvals include S2LA, ISO/IEC 17025:2005 and NADCAP AC 7101, AC 7122, mechanical testing and specimen preparation. They are also accredited for testing thermal properties.


STATICS LABORATORY

We conduct static property tests using mechanical, optical, or extensometry instrumentation - in any simulated environment. Typical tests, among others, include:

  • Tension / Compression
  • Flexure
  • Shear
  • Bearing
  • Bucking
  • Stress rupture

DYNAMICS LABORATORY

Typical dynamic property tests, among others, include:

  • Low-cycle Fatigue
  • High-cycle Fatigue
