Burning test:

   A small portion of cloth treated with synthetic resin is held to a Bunsen flame, and withdrawn after ignition. This
test is of most value with coated fabrics on which there is a substantial amount of coating. When only small percentages of resin are present, indications are often rather vague. Cellulose nitrate is very inflammable. Rubber has a characteristic odour.  Oxidised oil burns with a fatty smell. The various odours indicated in test 3 may be recognised under favorable circumstances.
