A sample, not a reference. These numbers were entered from memory and a study aid and have NOT been checked against the standard (SABS sells it). Several parts have newer editions (Part O edition 4 was published in 2025). Check every number against the current standard before relying on it. A rule the pack leaves out is simply not checked.
