Push Pull Testing For Construction Industry Supplying Calibrated Gauges. Mechanical Load Testing Methods For On Site Evidence To Testing Requirements.
Push pull testing is normally performed to measure how strong the fixings are between a typical bolt and concrete.
Push pull testing procedures are conducted to BS5080 Part 1 requirements.
Even though materials used for bonding may be different, it is important to note that testing for bonding strength is an universal principle.
Push pull testing and tensile strength testing is normally performed because many factors may effect apt bonding of the fixings. 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 entire strength of a whole set of fixings lose in strength so as to loose the integral strength of the structure because of the vital bonding materials being weak. Ultimately, this may cause the construction malfunctions leading to disastrous consequences. Push pull testing enables early diagnosis of such faults and defects. As a result, constructors can repair the problems. Early fault detection reduces future problems. This also helps to add to the assurance of any fixings integrity.
Push pull testing can be carried out either on a wide test batch or a smaller intensive scale. Testing always entails duplication of the design maximum stress levels planned 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 are decided upon 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 rapidly detect the scale of any identified problem.
Quicker Pull out testing (larger sample testing) may be used in instances when the costs of the mass testing is far reaching and faults 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 methods are the same as Push Pull Tests but only the pass or failure is recorded. While the Push Pull Tests can find problems the quicker Pull Out Tests will find out the extent of any identified problems.
