21 ista views • May 2018 • www.ista.org Tilt Test Results & Observations The results for the unit loads tested per the procedure identified in Section 2.2.2 are reported in Tables 3-5. The tilt angles identified in Table 3 are simply identifiers for subsequent testing. The third replicates for 15 tilt pre-test for AABBAA stack pattern were not undertaken due to failures observed in the subsequent mid-tilt tests towards ensuring the safety of the equipment and operators. Consequently, all tests for 20, 22.5 and 25 were omitted. The third replicates for 10 tilt test for AAAABB stack pattern were not undertaken due to failures observed in the subsequent mid-tilt tests towards ensuring the safety of the equipment and operators. Consequently, all tests for 15, 20, 22.5 and 25 were also omitted.
