Applicant's summary and conclusion

Executive summary:

 

The vapour pressure of Androstanolon-acetat was determined using a screening method based on the detection of the evaporation rate from a Knudsen cell of a vapour pressure balance at 25°C.

Androstanolon-Acetat was mixed with four other compounds. From all five test substances low or very low vapour pressures, based on the study directors experience were expected. For this reason the experiments consisted in the measurement of the evaporation rate of the mixture from a Knudsen cell at 25°C. Since the evaporation rate of the mixture was below the value derived from the lower limit of the vapour pressure range recommended for use of a vapour pressure balance (10^-3Pa, EU testing guideline A.4) it can be assumed that the vapour pressure of the mixture is lower than 10^-3Pa.

Considering this fact, the vapour pressure of the single compounds in the mixture has also to be lower than 10^-3Pa.

Therefore, the vapour pressure of Androstanolon-Acetat can be estimated to be at 25°C :

p₂₅< 10^-3Pa
