Downloaded from https://www.everyspec.com FM 34-54 SAMPLE IDENTIFICATION AND CONTROL 1. Samples acquired by a governmental source or provided by another source must be carefully controlled to be of the greatest value. To accomplish this, physical custody of the sample is maintained by a government representative. A sample identification number is also assigned and affixed to the sample or its container. 2. To prevent confusion, the sample number must be used when referring to the sample or to information concerning its acquisition. A sample number consists of the following elements: (a) Country of Acquisition.
This is a 2-digit alphabetic code for the country in which the sample was collected. The codes are found in DIAM 58-13, Volume II, Section E, dated 28 March 1988. (b) Date Acquired.

UIC of the unit that the collector is assigned to. (e) Collector Identification. The initials of the collector.
