Dichlorodifluoromethane

Flash point

Administrative data

Endpoint:

flash point of flammable liquids

Data waiving:

study technically not feasible

Justification for data waiving:

the study does not need to be conducted because the substance is a gas

the study does not need to be conducted because the flash point is only relevant to liquids and low melting point solids

Cross-reference

Cross-reference 1

Reason / purpose for cross-reference:

data waiving: supporting information

Reference

Key value taken from published data. 

Physical state at 20°C and 1013 hPa:

gaseous

Form:

gas under pressure: liquefied gas

Colour:

colourless

Two references are available that specify the substance is a colorless, practically odorless non-corrosive non-irritating non-flammable gas. It has a faint ether-like odor at high concentrations. The reference closely matches the registrants experience of the substance and is considered suitable for use, on the basis of a weight of evidence approach.

Cross-reference 2

Reason / purpose for cross-reference:

data waiving: supporting information

Reference

Vapour pressure: 566.6 kPa at 20°C

Vapour pressure:

566.6 kPa

at the temperature of:

20 °C

Five references are available for review. The reference values closely matches the registrants experience of the substance and is considered suitable for use, on the basis of a weight of evidence approach. The value at 20 deg C is chosen as the most appropriate one for use in the assessment process, as this closely matches values obtained from the other studies.

Cross-reference 3

Reason / purpose for cross-reference:

data waiving: supporting information

Reference

Low pressure Liquefied gas with critical temperature at or above 111.8°C

Critical pressure : 4123 - 4377 kPa
