Strength testing where you need it most

The hardness of a material is dependent on ductility, elastic stiffness, plasticity, strain, strength, toughness, viscoelasticity, and viscosity. This is an area for accuracy, not guesswork.

Hardness Testing applies force to measure resistance to penetration. This is used to identify material characteristics, or to quality check a sample meets particular specifications, vital for safe construction and effective ongoing operation.

IACS use specially-developed portable testing devices to permit in-situ hardness measuring, offering quick and economical supplements to conventional, stationary testing machines.

IACS experts can switch between two specialisms of Hardness Testing, for ultimate precision across a variety of materials and conditions.

Ultrasonic Contact Impedance (UCI) uses a resonating rod tipped with a Vickers diamond to measure frequency shift. It is well suited for pipes of all thickness, difficult to access positions, and heat affected zone hardness testing.

Rebound Testing measures the velocity of the impact body before and after test material impact. It is well suited for solid parts, coarse grain materials, steel and aluminium casting testing. Both convert results into highly accurate, digitally recorded hardness values.

Hardness testing made easy

Advantages of IACS Onsite Hardness Testing Inspections include:

  • Measures hardness value of products with any weights and thickness from 1 mm
  • Equipment functions in all directions, ideal for tight spaces and difficult test positions
  • Choice of testing processes for precision across varied materials and conditions
  • Fast, reliable, independent mobile measurements
  • Capable of taking measurements on large objects, and challenging component geometries
  • Non-destructive precision: minor mark enables testing mirror surfaces, neck shafts, knives, gear teeth
  • Highly reproducible results and lower sensitivity even in unsymmetrical test indentations (entire contact surface can be included in hardness calculations)
