This test is performed to measure the short-term strength of an installed Rockbolt under field conditions. The strength is measured by a pull test in which bolt head displacement is measured as a function of applied bolt load to give a load- displacement curve. This test is usually employed to assess the performance of the Rockbolt anchor resulting out of the quality of material used for manufacture of Rockbolt and installation method used. The test equipment consists of a manually operated hydraulic pump connected to hydraulic jack, having a high strength test rod, coupled to the Rockbolt under test. The anchor is tested by measuring the load until a total displacement greater than 40 mm has been recorded or until the bolt yield or fractures, if this occurs first. The readings of displacement are taken in increments of approx. 5 kN load or 5 mm displacement whichever occurs first. The rate of load application should be in the range 5- 1 0 kN/min. Readings are only taken after both load and displacement have stabilised. The time required for stabilisation should be recorded
