The catalytic substance, the heating conditions, the order in which the materials are added to the container, the support, and the concentration of the solution, all exert a notable influence on the final presence of catalyst in the samples. Consequently, they may also affect (in a different manner)

โฆ Synopsis
An evaluation of variations in the flexural strength of graphite determined in four-point bending tests has shown geometrical factors to have substantial influences on the measurement. Among the factors evaluated were the specimen cross-sectional geometry, ratio of load/support span to specimen thickness, and the use of rigid and nonrigid test fixtures.

The purpose of this work was to examine the tensile strength of coke and to relate this to fissure formation in industrial coke. The tensile strength was determined using the diametrical-compression test, the test specimens being obtained from half-oven-width lumps by drilling cores from a series of
