Testing of Physical Properties

The lab is equipped to measure the following physical properties of protective clothing fabrics:

  • Abrasion resistance
  • Flex cracking resistance
  • Puncture resistance
  • Tensile strength
  • Seam Tensile strength
  • Trapezoidal Tear resistance

All samples are conditioned for 24 hours prior to testing.

Where machine and cross direction is not indicated on a fabric, A and B will be ascribed to vertical and horizontal directions. Two sets of samples will be taken at 90° to each other in line with the textile backing. Where there is no textile backing or the weave cannot be seen, A and B directions will be ascribed at 90° to each other.

In the case of testing whole garments, the assumption is made that all panels within the garment have been cut in the same direction. A and B directions are ascribed at 90° to each other, vertical and horizontal as the suit is worn.

Please visit the UKAS web site at for a schedule of the tests which the lab is accredited to perform.
