Test on Tension tester (Skidmore-Wilhelm)
s005371
Test performance:
Test equipment according to the tables below.
Assemble selected test bolt set in the tester ensuring that threads and
pressure faces are well lubricated with Molycote Longterm W2 or sim-
ilar molybdenum disulphide lubricant.
Make 3 tightenings and check that the minimum tension can be
reached.
Test conditions:
Air pressure = 6.3 bar (90 psi) dynamic.
