Description
The PLF-100 is specifically engineered to evaluate the uncorrected point load strength index, denoted as "Is," which is then converted into a point load index standardized to a diameter (De) of 50 mm. This converted value, known as "Is(50)," serves multiple purposes, including rock strength classification and the estimation of parameters such as uniaxial compressive strength (UCS) and rock anisotropy, represented as Ia(50). This setup adheres to the procedures outlined in ASTM D5731, ensuring standardized and reliable testing methodologies. The fixture comes with a set of conical platens designed to accommodate disk-shaped specimens with diameters ranging from 25.4 mm (1-inch) to 101.6 mm (4-inches) and lengths equal to twice their diameter.
