As per IS 2911 (Part 4) : 2013 Uplift force may preferably be applied by meansof hydraulic jack(s) with gauge using a suitable pulloutset up. Pile top shall preferably be at cut-off level.Displacement measurement shall be made at pile topwith at least two dial gauges placed at diametricopposite ends of pile.

• The test pile shall have adequate steel to withstand pulling. In some cases, in order to allow for neck tension in a pull-out test, it may be necessary to provide additional reinforcement in the piles to be tested.

• The pull-out load increments and consequent displacement readings shall be read as in the case of vertical load test.

IS 2911 (Part 4) : 2013, The test may be carried out by introducing a hydraulic jack with gauge between two piles or pile groups under test or the reaction may be suitably obtained otherwise. If it is conducted by jack located between two piles or groups, the full load imposed by the jack shall be taken as the lateral resistance of each pile or group. The loading should be applied in increments of about 20 percent of the estimated safe lateral load.

• Lateral Load Testing: Lateral load testing is a method used to assess the behavior and capacity of deep foundation piles under horizontal or lateral loads. This type of testing is typically conducted to determine the pile's ability to resist lateral forces such as wind or seismic loads.
