| Description |
| The time during which, in specified storage conditions and when subsequently used in its specified |
| operational/training conditions, an explosive item may be expected to remain safe and serviceable. A Service Life |
| often depends upon the environmental influences to which the explosive will be/has been exposed (see JSP 482). |
| For explosives entering service, it is often necessary to assess an initial Service Life which is subsequently |
| subject to extension (STANAG 4315 and AOP-46). |
