7.0 POINT LOAD STRENGTH TEST PROCEDURE 1. Fill out chain of custody forms. 2. Open the relief valve on the hand pump. 3. On the load measuring gage press and hold the “Mode” key until the reading starts flashing. Release the “Mode” key, press the “Enter” key until the reading becomes 0.0. 4.USING THE POINT LOAD TEST TO DETERMINE THE UNIAXIAL,,Point load testing is used to determine rock strength indexes in geotechnical practice. The point load test apparatus and procedure enables economical testing of core or lump rock samples in either a field or laboratory setting. In order to estimate uniaxial compressive strength,Standard Test Method for Determination of the Point Load,,1.1 This test method covers the guidelines, requirements, and procedures for determining the point load strength index of rock. This is an index test and is intended to be used to classify rock strength.

Significance and Use 5.1 The uniaxial compression test (see Test Method D 2938) is used to determine compressive strength of rock specimens, but it is a time-consuming and expensive test that requires specimen preparation.

APPLICATIONS DESCRIPTION TEST PROCEDURE

TEST PROCEDURE Three point load test confi gurations are used depending on the available rock specimens: Diametrical – Axial – Irregular lump The diametrical and axial tests use core specimens with length/diameter (L/D) ratios greater than 1.0 in the fi rstPoint Load Test | JKTech,In a Point Load Test, a sample of rock is mounted between two pointed plates and pressure is applied until failure of the sample occurs. The peak applied load is recorded. This is repeated on a minimum of 20 pieces of rock within a sample with the results used to calculate the Point Load Index.Point Load Test,The point load test is a testing procedure used to determine the point load index and estimate the uniaxial compressive strength of rocks.
