Digital Point Load Test Apparatus consists of a 60 kN. read more... Zeal International. ... Load Capacity: 100kN. read more... Intellitest Solutions Private Limited. ... Point Load Index Tester, a rock testing instrument for determining the Diametrical Point Load Strength Index of rock cores and Irregular Lumps which may be tested.
The point load test was performed in accordance with the procedure described by Broch and Franklin  and standardized by ISRM . Digital Point Load test apparatus, model 45-D0550/D, made by Controls, England was used for Point Load testing of the rock samples (Figure 3). The core samples were diametrically loaded during the test.
The system is then placed in the loading apparatus which must be capable of applying a constant loading rate so that the specimen fails within 15-30 seconds. The maximum load is recorded. Typical loading devices designed for Brazilian Tests have a maximum loading capacity of 100kN.
