摘要
A method is proposed for planning and executing research involving accelerated ageing in studying the chemical stability of powder reference materials (RM) for spectral analysis. It is necessary to perform a series of experiments having various degrees of extremity in the instability factor in order to draw correct conclusions on the stability.
