• A list has been defined for RPLT_PLTF to include the test abbreviations derived from the ISRM Suggested Method (ISRM, 2007). Typically a test will include combined abbreviations to represent the sample type/orientation and the direction of the test with respect to bedding. For example a piece of core tested across the diameter and along the bedding direction will be coded as A.
