Flash point

Link to relevant study record(s)

Reference

Endpoint:

flash point of flammable liquids

Type of information:

read-across from supporting substance (structural analogue or surrogate)

Adequacy of study:

weight of evidence

Justification for type of information:

Target and source substances are highly similar, both structurally and chemically.

Reason / purpose for cross-reference:

read-across source

Qualifier:

according to guideline

Guideline:

EU Method A.9 (Flash-Point)

Deviations:

no

GLP compliance:

no

Type of method:

equilibrium method closed cup

Flash point:

> 125 °C

Atm. press.:

1 013 hPa

Preliminary measurement:

No flash point was observed in the preliminary test. To confirm this result the main test was performed.

Test item / ml	Starting temperature / °C	Measured flash point / °C
2	50, 100	---
4	100, 110	---
4	110, 115, 120, 125	---

Main Test:

At 120 °C the test item started to boil. Thus no flash point up to 125 °C could be detected.

Test item / ml	Temperature / °C	Ignition + / -	Barometric pressure / hPa
4	115	-	1016.8
	116	-	1016.8
	117	-	1016.8
	118	-	1016.8
	119	-	1016.8
	120	-	1016.8

Conclusions:

No flash point up to 125 °C could be detected.

Executive summary:

Flash point of uronium hydrogen sulphate was determined according to EU guideline A.9.

No flash point up to 125 °C could be detected.

Description of key information
