Abstract : The MACS XM232 case must meet radial and axial compression strength requirements in order to be used in an autoloader system. This study measured XM232 radial and axial compression strengths to determine if the French proposed JBMQU requirements were met. The XM232 current design exceeds the French requirements for mini- mum radial compression strength of 160.5 Ib with 3.5-mm deformation and minimum axial compression strength of 91.67 Ib with 2-mm deformation. The XM232 case had a minimum radial strength of 199 Ib and a minimum axial strength of 744 Ib. In addition to evaluation of standard XM232 cases, compression strength and drop test performance of special light weight XM232 cases were measured. Light weight cases cannot pass on angle drop test. This report concludes that the XM232 current design meets the proposed French requirements. Manufacture of a lighter weight case will require improved case strength properties. (MM)
