- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- Deviations:
- no
- Qualifier:
- according to guideline

- Specific details on test material used for the study:
- SOURCE OF TEST MATERIAL
- Test Substance Name: LZ 514
- Source: Lonza Ltd, Visp/Switzerland
- Lot/batch No.of test material: 5011
- Expiration date of the lot/batch: 2nd December 2017
- Manufacture date: 3rd December 2015
STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage conditions: Controlled room temperature (15-25 ºC, below 70 RH%), protected from light and humidity.
- Stability under test conditions: stable
- Safety precautions: Routine safety precautions (lab coat, gloves, safety glasses, face mask) for unknown materials were applied to assure personnel health and safety. - Key result
- Surface tension:
- 72.1 mN/m
- Temp.:
- 20 °C
- Conc.:
- 0.944 mg/L
- Remarks on result:
- other: saturated solution tested; estimated concentration based on water solubility ca. 0.944 mg/l
- Conclusions:
- The surface tension of a saturated solution of the test item was found to be 72.1 mN/m at 20°C, therefore, the test item is not classified as surface active.
- Executive summary:
The test was carried out according to EC method A.5, applying the ring method. A saturated solution with an estimated concentration of ca. 0.944 mg/L test item was tested. The surface tension was found to be 72.1 mN/m at 20°C; therefore the test item is not a surface active material.
