Step 1. After performing a visual inspection and operational check for baseline data, install the test item in its transit or combination case as prepared for field use (if measurement information is to be obtained, install and calibrate such instrumentation in this Step). If the test item operates satisfactorily, proceed to Step 2. If not, resolve the problems and repeat this step. Step 2. From paragraph 4.6.5.1 and Table 516.6-VI, determine the height of the drops to be performed, the number of drops per test item, and the drop surface. Step 3. Perform the required drops using the apparatus and requirements of paragraphs 4.6.5 and 4.6.5.1 and Table 516.6-VI notes. Recommend visually and/or operationally checking the test item periodically during the drop test to simplify any follow-on evaluation that may be required. If any degradation is noted, see paragraph 4.3.2. Step 4. Document the impact point or surface for each drop and any obvious damage. Step 5. Following completion of the required drops, visually examine the test item(s), and document the results. Step 6. Conduct an operational checkout in accordance with the approved test plan. See paragraph 5 for analysis of results. Step 7. Document the results for comparison with data obtained in Step 1, above
