Using a hydraulic or mechanical pull-off tester, apply a tensile force perpendicular to the surface. The standard specifies a constant rate of increase until fracture occurs. The machine records the maximum pressure (MPa) at break.

This is the most critical part. The standard defines five fracture surfaces: pdf iso -16276-1

The standard is explicit: Do not test if the steel temperature is within 3°C of the dew point. Moisture on the surface acts as a release agent. Furthermore, epoxy glues cure slower in the cold. Table 2 in the standard provides correction factors—use them. Using a hydraulic or mechanical pull-off tester, apply
