Manydata entries occur and laboratorytesting takes place.Given the fact that volumes, weightand % have tolerances the total resultneeds to give confidence that thewhole accounting, measuring andtesting system is reliable;Exceeding the level of 5% differencein balance might indicate errors thatrequire correction.Bonsucro Mass Balance ChoC Standard – Version 3.0 March 2011Including Bonsucro EU Mass Balance ChoC Standard© Bonsucro 2011/Bonsucro EU 2011Page | 13
