Any other information on results incl. tables

Drying loss

The drying loss of the substance was determined using a drying balance. The result was a value of 1.3 %.

Preliminary test

About 30 g methacrylamide were used to form the test pile (excess substance included).

After application of the flame at one end of the pile initially melting and afterwards ignition of the substance could be ascertained.

After removal of the ignition source extinction of the flame was observed.

> According to the guideline the performance of the main test was not necessary.
