Reference
Endpoint:
flash point of flammable liquids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
27 May 2010-09 July 2010
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Remarks:
This study has been performed according to OECD and EC guidelines and according to GLP principles. The test substance is adequately characterised. Therefore full validation applies.
Qualifier:
according to guideline
Guideline:
EU Method A.9 (Flash-Point)
Deviations:
no
Qualifier:
according to guideline
Guideline:
ISO 2719 (Determination of flash point - Pensky-Martens closed cup method)
Version / remarks:
2002
Deviations:
no
Qualifier:
according to guideline
Guideline:
ISO No., other: United Nations (UN), UN no. ST/SG/AC.10/11/Rev.4: Recommendations on the Transport of Dangerous Goods, Part III: Classification Procedures, Test Methods and Criteria Relating to Explosives of Class 3, Class 4, Division 5.1 and Class 9, Par. 32.4.1 , 2003
Deviations:
no
Qualifier:
according to guideline
Guideline:
ISO No., other: ASTM International, ASTM D 93: “Standard Test Methods for Flash Point by Pensky-Martens Closed Cup Tester”, December 10, 2002.
Deviations:
no
GLP compliance:
yes (incl. QA statement)
Type of method:
closed cup
Flash point apparatus:
Pensky-Martens apparatus
Remarks on result:
no flash point - measurement carried out until boiling temperature

It was visually observed that the test substance has a boiling temperature of approximately 104°C. No flammable vapour/air mixture was produced at temperatures below the boiling temperature of the test substance.

Interpretation of results:
GHS criteria not met
Remarks:
GHS and EU-CLP criteria not met
Conclusions:
As no flash point was observed, the substance is NOT classified as flammable liquid according to Regulation (EC) N°1272/2008 (CLP) criteria.
Executive summary:

The flash point of aluminium chloride hydroxide sulphate (as aqueous solution) was investigated according to EC/ISO guidelines, closed cup method. No flash point was recorded up to the observed boiling temperature of ca 104°C.

Description of key information

No flash point was recorded up to the observed boiling temperature of ca 104°C of the test substance (aqueous solution as manufactured).
The substance is NOT classified as flammable liquid according to Regulation (EC) N°1272/2008 (CLP) criteria.

Key value for chemical safety assessment

Additional information

A fully reliable experimental study, conducted according to a recognized ISO/EC method and under GLP, is available. It is therefore considered as a key study. As no flash point was observed up to boiling, no key data can be retained for purpose of CSA.

As an UVCB, it should be noted that the value of the parameter may show some variations.

This result is relevant for the classification regarding flammable properties.
