A data management system for material assessment at low temperature is developed in the context of large test programmes run in a current research project called Arctic Materials II. A generic database platform is proposed for efficient access to material data and to analyses of various materials such as steels/weldments, aluminium alloys, composites and polymers/coatings. Safe and flexible data processing accessible through a customized web interface is obtained by unifying test results, test methods, and procedures (e.g. tensile testing, fracture mechanics testing) and predictive models of fracture. The framework provides a solid support for the development of more robust solutions to account for the influence of, e.g., temperature, constraint effects, residual stresses, crack arrest, probabilistic scatter, and scaling on the material response. Its aim is also to contribute to an improved design guideline for materials requirements in Arctic conditions (down to -60°C)
