Test System

 

The flammability (solids) was determined by measuring the burning rate of test item prepared as a pile of set dimensions. Testing was conducted using a procedure designed to be compatible with Method A10 Flammability (Solids) of Commission Regulation (EC) No 440/2008 of 30 May 2008.

Principle of the Test

 

The flammability (solids) was determined by measuring the burning rate of the test item.

 

Preliminary screening test

 

A mould (250 mm long x 20 mm wide x 10 mm high) was loosely filled with test item (tested as received). A non-combustible, non-porous board was placed onto the mould which was then inverted. The mould was removed and an air-rich Bunsen burner flame applied to one end of the pile for two minutes.

 

Data Handling

 

If the test item does not ignite and propagate combustion either by burning with a flame or smoldering along 200 mm within 4 minutes, the test item is not considered as highly flammable and no further testing is required.

 

If the test item propagates burning of a 200 mm length in less than 4 minutes, the main test is performed.

 

Result - Preliminary Screening Test

 

The pile failed to ignite during the 2 minutes that the Bunsen flame was applied.

 

The result of the preliminary screening test obviated the need to perform the main test.

The test item has been determined to be not highly flammable as it failed to ignite in the preliminary screening test.

 

Applicant's summary and conclusion

Interpretation of results:

non flammable

Remarks:

Migrated information

Conclusions:

Not highly flammable, using a procedure designed to be compatible with Method A10 Flammability (Solids) of Commission Regulation (EC) No 440/2008 of 30 May 2008.

Executive summary:

Introduction

Hazardous physico-chemical properties of the test item have been determined. Methods employed were designed to be compatible with those specified in Commission Regulation (EC) No 440/2008 of 30 May 2008, Part A: Methods for the determination of physico-chemical properties.

Method

The flammability (solids) was determined by measuring the burning rate of test item prepared as a pile of set dimensions. Testing was conducted using a procedure designed to be compatible with Method A10 Flammability (Solids) ofCommissionRegulation (EC) No 440/2008 of 30 May 2008.

Results Preliminary Screening Test

The pile failed to ignite during the two minutes that the Bunsen flame was applied. The result of the preliminary screening test obviated the need to perform the main test.

Conclusion

The test substance was considered to be not highly flammable.
