10.1.1 A thorough description of anticipated events associated with the item of equipment from the time of Tmal factory acceptance until its terminal e]q>enditure or removal from inventory.

10.1.2 A list of significant narura! and induced environments or combinations of environment for each anticipated shipmenttransporfstoragc/logistic event such as transportation, dormant storage, stand-by, bench handling and ready modes, etc.

10.1.3 List the necessary data, in narrative and statistical form, outlining the environmental and stress condinons to uriiich the equipment will be subjected during its various life phases. The data may be from caladation, laboratory tests and cperatitKtal measurements. When such information is based on estimates, it shall be replaced by actual values as diey are determined. The profile shall show the number of measurements from which the -average value of these stresses and design achievements are determined as well as their characteristics variability which shall be expressed in terms of standard deviation.
