Linear calibration of axial load fatigue testing machines (NT TR 579)

NT TR 579

  • A method of linear calibration of axial load fatigue testing machines is proposed. It is built on the understanding obtained from a vibration analysis of the force transfer function from the load cell of the machine to a fabricated calibration bar. The results have been successfully verified on a commercial testing machine installed at SP in Borås.

CEN EN 12457 leaching test - Comparison of test results obtained by part 1 and 2 with test results obtained by part 3 (NT TR 539)

NT TR 539

  • The report compares leaching results obtained by two one-step batch leaching tests (en 12457 part 1 and 2) with leaching results obtained by a two-steps batch-leaching test (EN 12457 part 3). The effect of the used contact time and the effect of using different number of leaching steps were evaluated.

Building gaskets: Deformation resistance (NT BUILD 108)

NT BUILD 108

  • This test method is used to find if a building gasket has a sufficiently low resistance to deformation when it is installed or during actual use.
