UCS P d= u (1) 4. Point Load Test The ASTM-D5731-08 [8] code gave a clear justification for the use of the point load test. The code started its justification by giving statements about the time and money spent on performing a UCS test and recommended the use of simpler in-situ tests of which the point load test was one of them.

5.1.1 Flexural Stress (σ f)— When a homogeneous elastic material is tested in flexure as a simple beam supported at two points and loaded at the midpoint, the maximum stress in the outer surface of the test specimen occurs at the midpoint. Flexural stress is calculated for any point on the load-deflection curve using equation (Eq 3) in Section 12 (see Notes 5 and 6).

The Point Load Test, also known as the Point Load Strength Index Test, is used to calculate the rock strength index of a rock specimen. From the rock strength index, other rock parameters, such as the uniaxial compressive strength, can be estimated.This test is very economical due to the simplicity of the apparatus and the minimal amount of required materials to execute.

Point Load Index (Strength) ASTM D 5731 Purpose To determine strength classification of rock materials through an index test. Procedure Rock specimens in the form of core (dia metral and axial), cut blocks or irregular lumps are broken by application of concentrated lo ad through a pair of spherically truncated, conical platens.

1.1 This test method covers the guidelines, requirements, and procedures for determining the point load strength index of rock. Specimens in the form of rock cores, blocks, or irregular lumps can be tested by this test method. This test method can be performed in the field or laboratory because the testing machine is portable.
