Plastiques alvéolaires rigides — Détermination du fluage sous compression dans des conditions spécifiées de charge et de température

Specifies a method for the determination of compressive creep of rigid cellular plastics under specified conditions of load, temperature and time. Test specimes in form or rectangular parallelepipeds are placed between two flat plates and the specified load is applied a) at standard conditions and b) at agreed conditions of temperture and time. The difference in compressive deformation of the loaded specimen at standard atmospheric conditions and at elevated temperature shall be calculated.
