SCOPE:1.1 Form:This specification covers a glycol-base deicing/anti-icing mat
6、erial in theform of a liquid.1.2 Application:This fluid has been used typically on airport runways and taxiways for theprevention and removal of frozen deposits of frost and ice, but usage is notlimited to such applications.1.3 Precautions:1.3.1 Deicing/anti-icing formulations may be mildly toxic an
7、d contact with humanskin and eyes should be avoided. Prolonged exposure to concentrationsexceeding the established threshold limit values (TLV) for the product orits major components should also be avoided.1.3.2 Caution should be exercised in the use of aqueous glycol deicing/anti-icing solutions in
8、 and around aircraft having silver or silver-coatedelectrical/electronic circuitry. Dehydrolysis reactions which result infire may occur when such aqueous glycol solutions contact silver orsilver-coated circuits, such as defectively insulated wires, switches, orcircuit breakers, which are carrying d
9、irect current.1.3.3 Airport authorities should ascertain the friction coefficient of the runwayafter application of the deicing/anti-icing fluid.SAE Technical Standards Board Rules provide that: This report is published by SAE to advance the state of technical and engineeringsciences.
