Specific details on test material used for the study:

Name: HES 10108 (supplied as Dow Corning® BY 16-122 B)
CAS No.: Not Listed
ID No.:HESI0108
Lot No.: 0008624816
Source: Dow Corning Corporation, Auburn, Michigan
Physical Description: Colorless liquid
Purity: 99.3%, used as 100%
Storage Conditions: Room Temperature
Expiration Date: 25 August 2017

(1) Following addition of the test substance to an evaporating trough containing water at room temperature, no evolved gas was observed; no ignition was observed.

(2) Following addition of the test substance to filter paper on the surface of water at room temperature, no evolved gas was observed; no ignition was observed.

(3) Following drop wise addition of water at room temperature onto the test substance, no evolved gas was observed; no ignition was observed. Test substance was observed to completely separate from water with no visual indications of water reactivity.

(4) The rate of evolved gas from the test substance was determined in triplicate. The rate was measured to be 0 L/kg per hour in each ofthe three determinations.

Therefore, it can be concluded that the test substance is not flammable when in contact with water or damp air.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

(1) Following addition of the test substance to an evaporating trough containing water at room temperature, no evolved gas was observed; no ignition was observed.
(2) Following addition of the test substance to filter paper on the surface of water at room temperature, no evolved gas was observed; no ignition was observed.
(3) Following drop wise addition of water at room temperature onto the test substance, no evolved gas was observed; no ignition was observed. Test substance was observed to completely separate from water with no visual indications of water reactivity.
(4) The rate of evolved gas from the test substance was determined in triplicate. The rate was measured to be 0 L/kg per hour in each ofthe three determinations.
Therefore, it can be concluded that the test substance is not flammable when in contact with water or damp air.

Executive summary:

The purpose of this study was to determ ine whether the reaction of test substance with water or damp air leads to the development of dangerous amounts of gas or gases which may be highly flammable. This study was conducted according to the Smithers Viscient protocol entitled "HES] 0108 Determination of the Flammabi I ity (Contact with Water) Fo lIowing the Official Journal of the European Communities L 142/87, Method A.12". Under the conditions of the study -
