I have a 5# loaded box with dim's 10"x12"x23". ISTA 1C says 374# comp load. What is rationale for this large load?

The compression testing in ISTA 1C is a pre-conditioning test that is not intended as a compression performance test or a predictor of warehouse or vehicle stacking capability. The compression pre-conditioning sequence in ISTA 1C was put in place with mixed-commodity loads in mind. The theory being that, in a mixed commodity load, you won't know the weight of packages stacked on top of your own. The compression pre-conditioning sequence is an extension to the ISTA 1A procedure which does not have a compression element.
Whether you are utilizing the correct ISTA standard depends on your driving force behind your package testing. ISTA 1-Series are the most basic category of performance tests. They challenge the strength and robustness of the product and package combination. They are not designed to simulate environmental occurrences but are useful as screening tests, particularly when used as a consistent benchmark over time. If this doesn't fit the description of what you are looking to get out of your testing, I would suggest exploring an ISTA 2-Series test, 3-Series test or 4-Series test.
