Reference

Endpoint:

surface tension

Type of information:

experimental study

Adequacy of study:

key study

Study period:

28.8.2017

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

test procedure in accordance with generally accepted scientific standards and described in sufficient detail

Qualifier:

equivalent or similar to guideline

Guideline:

OECD Guideline 115 (Surface Tension of Aqueous Solutions)

Principles of method if other than guideline:

The room temperature was +23 ºC and the equipment, water and the sample were allowed set
to room temperature several hours before measurement.
The ring of the equipment was cleaned by gas flame torch before analysis and let cool.
The equipment was checked before analysis by room temperature (23 ºC) pure water.
The 2 replicated analysis were measures for the sample and the results were 71.0 and 69.5.

GLP compliance:

no

Other quality assurance:

ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories)

Type of method:

OECD harmonised ring method

Specific details on test material used for the study:

Fain 3, batch 406-407
