Push Pull Testing For Railway Industry With Calibrated Gauges. Stress Load Testing Procedures For On Site Proof To Testing Requirements.
Push pull testing is normally performed in order to gauge how strong the material bonding is between a typical bolt and concrete.
Push pull testing procedures are conducted to BS5080 Part 1 requirements.
No matter what 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 impinge upon apt bonding of the fixings. The biggest concern is that some of these factors may pass unnoticed when only visual inspection is conducted. Among these are damage caused to the bonding material resulting from low temperature, frost, or when water infiltrates into the joining compound. Another reason for poor surface bonding strength is as a result of smooth side walls.
The entire strength of the whole structure may be weaker so as to loose the integral strength of the structure due to the vital bonding materials fail. Ultimately, this may cause the construction failures leading to disastrous consequences. Push pull testing means early detection of such faults and defects. Because of this, constructors are able to rectify faults. Early fault detection reduces future higher costs. It also gives an assurance of any fixings overall strength.
Push pull testing is conducted either on a wide test batch or a smaller intensive scale. Testing always entails maximum design load stress testing planned in construction as stipulated by the standards of the industry. This is not destructive testing so the maximum loads applied together with the sample size are determined by the on-site engineers.
Push Pull Testing is a detailed stress testing study of the performance of bonded materials. Should problems be found then the Pull Out Testing could be used to quickly find out the scale of any problem.
Quicker Pull out testing (larger sample testing) could be used in instances when the costs of the mass testing is far reaching and faults have been found.
Pull Out Tests can quickly test more fixings and will only show the pass or fail of maximum loads being tested. The test procedure are identical as Push Pull Tests but only the pass or failure is recorded. While the Push Pull Tests can find problems the rapid Pull Out Tests will find out the extent of such problems.
