The test tube (PVC pipe) and the 32-lb weight constitute the spring compression test set.
The spring compression test set is locally manufactured IAW WP 0113 00.
Perform a compression test during initial receipt, during each re-pack and each time

compressed/packed for 365 days).
Perform the spring compression test as follows:

2. Place the spring inside the tube.
3. Lower the 32-pound weight onto the spring.
4. Check to ensure that the spring is visible between the 6-inch slot in the tube.
