Stability: thermal, sunlight, metals
Administrative data
Link to relevant study record(s)
- Endpoint:
- stability to metals
- Type of information:
- read-across based on grouping of substances (category approach)
- Adequacy of study:
- key study
- Study period:
- From 03 November, 1994 to 17 November 1994
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study without detailed documentation
- Remarks:
- according to DIN 50905, Part 4
- Justification for type of information:
- Refer to the Quaternary ammonium salts (QAS) category or section 13 for details on the category justification. The study with the read across substance is considered sufficient to fulfil the information requirements as further explained in the provided endpoint summary.
- Qualifier:
- according to
- Guideline:
- other: DIN 50905, Part 4
- Deviations:
- no
- Conclusions:
- Under the conditions of the study, the test substance caused pitting with hole depth of 30 and 50 µm in 14 days.
- Executive summary:
A 14 days study was conducted to determine the metal corrosion potential of the read across substance, C16 TMAC. Under the conditions of the study, the test substance caused pitting with hole depth of 30 and 50 µm in 14 days (Hoechst, 1994). The corrosion rate is expected to be below the 6.25 mm/year cut-off for classification given in the ECHA guidance to Regulation EC 1272/2008, corresponding to an intrusion depth of 240 µm in 14 day.

Description of key information
The metal corrosion was determined for the read across substance, C16 TMAC, according to DIN 50905 (Hoechst, 1994). Additional information
Value used in CSA: Not corrosive to metals
Justification for classification or non-classification
The localised corrosion rate is expected to be below the 6.25 mm/year cut-off in the CLP for classification, based on a hole depth of 30 or 50µm (as per the results for a 14 day study).
