Push Pull Testing For Railway Industry With Calibrated Measuring Instruments. Mechanical Load Testing Methods For On Site Documentation To Testing Standards.


Push pull testing is normally performed in order to gauge how strong the material bonding is between a typical fixing and concrete.

Calibrated push pull force gauges are used to measure mechanical load testing strengths of the fixings.

Regardless of the type of bonding material used, it is important to note that testing for bonding strength is an universal principle.

Push pull testing and tensile strength testing is usually performed because a myriad of factors may effect proper bonding of materials. The biggest concern is that some of these factors may go unnoticed when only visual inspection is conducted. Among these are damage caused to the bonding material resulting from low temperature, frost, or when contaminants infiltrates into the joining compound. Another cause of insufficient bonding strength is as a result of smooth side walls.

The overall integrity of a whole set of fixings may be weaker so as to loose the complete strength of the structure because of the vital bonding materials being weak. Ultimately, this may result in construction failures leading to disastrous results. Push pull testing enables early diagnosis of such faults and defects. As a result, constructors can rectify faults. Early fault finding reduces future problems. It also gives an assurance of any structure's integrity.

Push pull testing is conducted either on large scale or a smaller intensive scale. Testing always entails maximum design load stress testing anticipated in construction as required by the standards of the industry. This is not destructive testing so the maximum loads applied together with the sample scale of the tests will be determined by the on-site engineers.

Push Pull Testing is a sampling as a quality assurance measure. If problems have been detected then the Pull Out Testing could be used to quickly detect the scale of any identified problem.

Quicker Pull out testing , on the other hand, could be used in instances when the financial feasibility of the mass testing is far reaching and problems have been found.

Pull Out Tests are for strength testing only and will only show the pass or fail of maximum loads being tested. The test procedure are the same as Push Pull Tests but only the pass or failure is recorded. Push Pull Testing is normally used to detect problems the rapid Pull Out Tests will find out the extent of any identified problems.

Some Of The Many Improvements In Carbide Inserts Coming From Iscar From Over The Years
Iscar is introducing a new unique milling system with tangential, clamped, butterfly-shaped LNKX carbide inserts. The butterfly-shaped insert has significant advantages compared to the current flat, square shapes. The new geometry has more cutting edges, positive rake face, reduced cutting forces resulting in higher performance.

New End Mills Coming From Iscar Will Enhance Productivity While Lowering Costs
Manufacturers and die & mold shops can banish chatter problems in numerous milling operations with Iscar's new Chatterfree end mills. The cutters' variable-pitch flute pattern eliminates harmonic vibration, the primary source of chatter. This enables faster cutting and finer finish in rough or finish slotting, shoulder milling and cavity milling.
