The EGTCT and any of its components for which the Governments unit cost is more than $5,000, is serially managed, or 16 September 2010 D-3 the procuring agency determines is mission essential, shall have Unique Identification (UID) (also known as Item Unique Identification (IUID)
20、information permanently affixed on or near the respective identification plate(s), marked in accordance with MIL-STD-130. UID information shall be included as both a bar code and human readable markings. 2.10 Calibration. The EGTCT shall not require calibration more than once every year and it shall
21、 not require any special equipment, rooms or chambers to accomplish the calibration. The mean time to calibrate shall be 2 hours or less. Calibration standards shall be traceable to NIST. 2.11 Component protection. All space in which work is performed during operation, service, and maintenance shall
