Bis(2-chloroethyl) ether

Flammability

Link to relevant study record(s)

Reference

Reference 1

Endpoint:

flammable solids

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

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

Justification for type of information:

Bis(2-chloroethyl) ether is a liquid at 20°C and 1013 hPa.

Reference 2

Endpoint:

flammable gases

Remarks:

flammability of vapour

Type of information:

experimental study

Adequacy of study:

key study

Study period:

From 19 July 2017 to 24 August 2017

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

other: ASTM E681: Standard Test Method for Concentration Limits of Flammability of Chemicals (Vapours and Gases)

Deviations:

no

GLP compliance:

Specific details on test material used for the study:

TEST MATERIAL
- Name (as cited): DCEE
- Purity: 99.8%

SOURCE OF TEST MATERIAL
- Source and lot/batch No.of test material: n°SHBD4430V
- Expiration date of the lot/batch: 02/06/2017

STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: room temperature

Key result

Parameter:

lower explosion limit

Value:

1.75 vol%

Remarks on result:

other: at 105°C

Key result

Parameter:

upper explosion limit

Value:

> 17.2 vol%

Remarks on result:

other: at 140°C

The lower and upper flammability limits were determined using 5 experimental measurements.

The upper flammability limit cannot be exactly determined due to the apparatus technical limitations. Indeed, the maximum temperature that the apparatus can reach is 140°C. At this temperature, an orange flame was observed.

Interpretation of results:

other: This study was used for additional labelling provisions as required by CLP for flammable liquid

Conclusions:

The lower flammability limit of the test item vapour is 1.75% (v/v) at 105°C.
The upper flammability limit of the test item vapour is >17.2 % (v/v) at 140°C

Executive summary:

The lower and upper flammability of test item vapors have been determined according to a recognized guideline. No deviation from this guideline was observed in the study.

 

The lower flammability limit of the test item vapour is 1.75% (v/v) at 105°C.

The upper flammability limit of the test item vapour is >17.2 % (v/v) at 140°C. The upper flammability limit cannot be exactly determined due to the apparatus technical limitations.

Description of key information

As the substance is a liquid, this endpoint is obsolete (already covered by the Flash point).

Key value for chemical safety assessment

Flammability:

not classified

Additional information

CLP regulation require additionnal information for flammable liquid. For substance without flash point up to 60°C and that can eventually lost non-flammable components, the explosion (or flammable) limits should be determined .

The lower and upper flammability of test item vapors have been determined in a key study of Klimisch validity one.

The lower flammability limit of the test item vapour is 1.75% (v/v) at 105°C.

The upper flammability limit of the test item vapour is >17.2 % (v/v) at 140°C. The upper flammability limit cannot be exactly determined due to the apparatus technical limitations.

Based on these limits, the test item is labelled with the additional information EUH018 according to CLP.
