As the burn time was greater than 45 seconds in each case, the test item was determined not to be highly flammable.

Applicant's summary and conclusion

Interpretation of results:
not classified based on GHS criteria
Conclusions:
The burn time of six replicates of WS-23 using a test mould and an ignition source was greater than 45 seconds in each case. Therefore, WS-23 was determined not to be highly flammable.
Executive summary:

WS-23 was tested for flammability (solids) using a a test mould and an ignition source. The burn time of six replicates of WS-23 was greater than 45 seconds in each case, therefore, WS-23 was determined not to be highly flammable.
