The NO-17-A205:2017 "Airfield maintenance in winter. Use of de-icers. Requirements and tests" Military Standard is applicable at Polish Armed Forces airports in the process of winter maintenance of airport pavements, both in the process of supplying airports with de-icing agents based on acetates and formates, as in testing, acceptance and control of de-icing agents based on formates, acetates and urea. After the expiration date of product, the tests specified in NO-17-A205:2017 shall be repeated. Purpose of the research is to determine physico-chemical properties changes of de-icing agents applied on artificial airfield pavements, after its expiration dates. The results of research on physical and chemical parameters of de-icing agents obtained at the stage of delivery and after its expiration dates have been given. The tests included determination of appearance, density, refractive index and pH value measurement, as well as checking the freezing point temperature and, in the case of deicing agents in form of granulate, checking the granules size distribution. The requirements and test methods for deicing agents in accordance with NO-17-A205:2017 are also presented. In case of parameters changes, recommendations regarding further use of these agents shall be made. Positive tests results shall be the basis for extending the shelf life of de-icing products for the next winter season.
