A description is given of work which has enabled the Williams-Landel- Ferry WLF method of time temperature superpositioning of tensile test data to be applied to the routine assessment of experimental plastic propellant compositions. The report is in two parts. The first part deals with experimental improvements which have recently been made particularly with regard to the estimation of the effective gauge length a comparison of the procedure with the American ICRPG standard method is included. The second part deals with the computerization of the calculations performed on tensile data. This has enabled the time required to carry out a WLF analysis to be reduced from one week to about one day.
