scope:

This procedure describes a method for testing the flame resistance of paper and paperboard not over 1.6 mm (0.063 in.) in thickness that has been treated to prevent the spread of flame when ignited.

It also provides a parameter of quality and utility by distinguishing between paper or paperboard having a non-durable treatment (removed by leaching in water), designated as Type I, and paper or paperboard having a durable treatment (not removed by leaching in water), designated as Type II.

Safety precaution. This test method measures the resistance to flaming under specified test conditions. Any judgements regarding suitability for use in predicting end use applications of specific papers must be made by the user.

This test method does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this method to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Special attention should be given to the Material Safety Data Sheets (MSDS) of the gases used and to the manual for the use of the burner in 3.3.
