The thrust of a 556mm

proof load measures approximately 5,183 lbs.

e2b calibration, an ISO/IEC 17025 accredited calibration that offers onsite aircraft jack

proof load testing and nondestructive aviation equipment testing, is now offering aviation maintenance education on its calibration.aero website, the company said.

The

proof load for the .455 was 18,440 PSI with service ammo producing about 13,000 PSI.

GMI composite manhole covers and frames have an average

proof load in excess of 100,000 pounds - more than five times the H-20 loading standard per AASHTO (American Association of State Highway and Transportation Officials) Standard Specifications for Highway Bridges.

WATER WEIGHTS LTD, provides specialist

proof load testing equipment for load bearing structures and lifting equipment.

The crane was tested with a safe working load of 80 tons and a

proof load of 100 tons.

Table 1 summarizes the applied and observed tensile failure loads of the DLJ and the type of AE sensor use for monitoring the

proof load. The average tensile failure load for all DLJ, irrespective of their bond-line thickness is 182.4 [+ or -] 28 kN, and 199.1 [+ or -] 42 kN, 169.9 [+ or -] 23 kN and 178.5 [+ or -] 11 kN for 0.3, 0.5 and 1.0 mm bond-line thickness, respectively.
