Selected anticorrosion preserving agents were subjected to a comparison on the basis of tests made under operating conditions. Resistance of materials to corrosion markedly varies with operating conditions and impact of outer environment with the most important factors influencing the corrosion rate being SO2 content, temperature and humidity. Relative protective efficiency of preserving agents was assessed on the basis of weight losses of protected and unprotected samples. It was found out that the material’s resistance to corrosion is significantly depending on warehousing conditions (SO2, temperature, humidity, etc.) and on the quality of the applied preservant. Depending on various environments, the values of relative protective efficiency of water-soluble preservant and preserving agent based on vegetable oils were ranging from 38–87% and 47–75%, respectively.Keywords:
