PHASE 11 REPORT ON INSPECTIONS OF INSULATION-JACKET TYPE THERMAL SHIELDS ON TANK CARS IN ACCELERATED LIFE TESTS

Four 112A tank cars were retrofitted with one inch of a mineral fiber insulation and a steel jacket. The jacket thickness was 11 gage over the shell and 1/2 inch over the heads. Design details of each application were different. The cars were sent to the DOT Transportation Test Center at Pueblo, Colorado, where they were placed in an Accelerated Life Test (ALT) program. This program will simulate 10 years of service life by running the cars 160,000 miles and subjecting them to a series of impacts as would be encountered in switchyards. A glass fiber insulated 111A car also was included in the program as a reference base. The results of inspections after 2 to 5 years simulated life are given in this report. These inspections revealed nothing that would indicate that this type of "112J" car insulation system will not maintain its integrity over the life of a tank car.
