ISTA 1A is for packaged-products 150 lb. (68 kg) or less, and challenges the strength and robustness of the product and package combination to withstand transport hazards. Procedure 1A is useful particularly when used as a consistent benchmark over time.
Many medical device manufacturers use ISTA Procedure 1A. This procedure was developed for a quick and easy way to evaluate a shipping configuration for drop testing and repetitive shock vibration. This procedure does not take into a account random vibration or atmospheric pre-conditioning.
Test Procedure 1A is broken down into two categories: Vibration and Shock:
When properly applied, ISTA procedure 1A will provide tangible benefits of:
| Sequence | Test Type | Standard | Description |
| 1 | Vibration | ASTM D999 | Fixed Displacement, Rotary, Vertical Linear Motion |
| 2 | Drop | ASTM D5276 | Free Fall |
