CC-series Crush cell

ISO 13503-2 - API RP 19C


The CC-series crush cell is engineered to evaluate the crushing resistance and degradation properties of proppants employed in hydraulic fracturing processes. According to API definitions, crush resistance is quantified as the weight percentage of proppant that passes through the smallest mesh size in the pre-specified original size distributions. The piston utilized in the apparatus has dimensions of 2.0x3.5 inches (50.8x89 mm). Testing is executed in alignment with API RP 19C and ISO 13503-2 standards, carried out at ambient temperatures and under various closure stresses, with a maximum limit of 15,000 psi.
