## What is Point Load Test?

*NOTE: This is a new version of the PLT app. The old version will remain listed in the meantime but will be removed soon.

The Point Load Test Application was designed to be used in conjunction with a GCTS PLT-2W. This application allows the user to easily perform tests and record data by connecting to a PLT device via Bluetooth.

The device will output load and displacement from a pair of sensors, which will be read by the app and used to calculate point load test results. The app allows two-step calibrations of these readings, and also can obtain pre-loaded calibration factors from within the PLT-2W.

Using this application, specimen measurements can be made with ease. By simply placing the specimen in the apparatus as shown in the application and applying a small load, the application will automatically calculate the dimension of the specimen in that axis. This app can be used with diametral, axial, or irregular specimens. In addition, the application can be set to reuse certain dimensions, so if a core sample is used, the application can be set to use the same diameter for each specimen tested.

The operator can also define a custom equation for determination of the unconfined compressive strength from the point load strength index as calculated by the test. The application will automatically graph the load versus equivalent core diameter and automatically calculate the unconfined compressive strength for the rock specimen.

This app also allows the measurement of Ultrasonic P-Wave Velocities when paired with a ULT-2 or ULT-200.

## Frequently asked questions about Point Load Test

### What is Point Load Test used for?

Point Load Test is used for performing point load tests on rock specimens to determine their strength. It calculates results by measuring load and displacement from connected sensors and can also measure Ultrasonic P-Wave Velocities.

### What devices is Point Load Test compatible with?

Point Load Test is available for iPhone, iPad, and iPod devices. It requires a GCTS PLT-2W device for point load testing and can also connect to a ULT-2 or ULT-200 for P-Wave velocity measurements.

### How does Point Load Test measure specimen dimensions?

The application automatically calculates specimen dimensions by simply placing the specimen in the apparatus and applying a small load. It can be used for diametral, axial, or irregular specimens and allows for reusing dimensions for core samples.

### Can I customize strength calculations in Point Load Test?

Yes, the operator can define a custom equation for determining the unconfined compressive strength from the point load strength index. The app will then automatically calculate this value.
