These test methods cover the determination of flammability of paper and paperboards of all types no more than ¹/₁₆ in. (1.6 mm) in thickness, that have been treated to retard the spread of flame when ignited. Such papers are commonly designated as flame-retardant-treated.

Formerly under the jurisdiction of Committee D06 on Paper and Paper Products, these test methods were withdrawn in August 2009 due to insufficient committee interest in reviewing and revising the standard.

The utility of paper and paperboard for many functional and decorative purposes requires resistance to the spread of flame. These test methods are useful in both qualitative and quantitative measurement of the flame retardant property of paper and paperboard. Certain uses may also require a knowledge of the durability of the flame-retardant treatments applied to paper and paperboard when exposed to water. Judicious analysis of the test data may be useful for design purposes in applications and fabrication of materials requiring flame-resistant properties.

1.1 This is a fire-test-response standard.

1.2 These test methods cover the determination of flammability of paper and paperboards of all types no more than 1/16 in. (1.6 mm) in thickness, that have been treated to retard the spread of flame when ignited. Such papers are commonly designated as flame-retardant-treated.

1.3 These test methods may be used with, and may be used to distinguish between, paper and paperboard materials having a flame-retardant-treatment removed by leaching in water, and those whose flame-retardant-treatment is not removed by water leaching.

1.4 These test methods appear as follows:

1.5 The primary intended use of Test Method A is with paper or paperboard materials having a flame-retardant treatment that is not removed by water leaching, or to specify the properties of such materials.

1.6 The primary intended use of Test Method B is with paper or paperboard materials having a flame-retardant treatment known to be removed under the leaching conditions specified in Test Method A, or where non-removal of the flame-retardant treatment by water leaching is not a desired or specified property.

1.7 This standard should be used to measure and describe the properties of materials, products, or assemblies in response to heat and flame under controlled laboratory conditions and should not be used to describe or appraise the fire hazard or fire risk of materials, products, or assemblies under actual fire conditions. However, results of this test may be used as elements of a fire risk assessment which takes into account all of the factors which are pertinent to an assessment of the fire hazard of a particular end use.<.i>

1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
