PHASE 09 FINAL REPORT ON BOTTOM FITTINGS PROTECTION TEST PROGRAM
In response to a Notice of Proposed Rulemaking issued by the Environmental Protection Agency, the AAR mandated certain requirements to reduce the probability of loss of lading in derailments. This study was undertaken to determine the fatigue life and assess the protective capability of skids. Five designs were fabricated and applied to cars equipped with various type outlets and appropriately strain gaged. In addition, three "base" tests were conducted on cars without protective skids. This report describes the entire test program and analysis and conclusions are given. An Addendum to this report will be issued at a later date that will include an analysis of strain gage data of the destructive impact tests to determine if any existing engineering method of analysis is applicable and the results of the "fail-safe" siphon pipe test.
