Non-destructive testsand examinations should be carried out prior to any destructivetesting, and destructive testing should be kept to a minimum,and thoroughly documented. If exempla

If proposed tests,examinations, or other actions are likely to alter the nature,state, or condition of the evidence so as to preclude or limitadditional examination or testing, the p
