Standard Test Methods for Flammability of Treated Paper and Paperboard
|Publication Date:||10 May 1997|
1.1 These test methods cover the determination of flammability of papers and paperboards of all types not more than 1/16 in. (1.6 mm) in thickness, that have been treated to prevent the spread of the flame when ignited. Such papers are commonly designated as flameproofed.
1.2 These test methods may be used with, and may be used to distinguish between, paper and paperboard materials having a flame-resistant treatment removed by leaching in water, and those whose flame-resistant treatment is not removed by water leaching.
1.3 These test methods appear as follows:
Section Test Method A---Flammability of Treated Paper and Paperboard 8.1 After Leaching for 4 h With 24[deg]C Reagent Water Test Method B---Flammability of Treated Paper and Paperboard 8.2 Without Leaching
1.4 The primary intended use of Test Method A is with paper or paperboard materials having a flame-resistant treatment that is not removed by water leaching, or to specify the properties of such materials.
1.5 The primary intended use of Test Method B is with paper or paperboard materials having a flame-resistant treatment known to be removed under the leaching conditions specified in Test Method A, or where non-removal of the flame-resistant treatment by water leaching is not a desired or specified property.
1.6 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.
1.7 This standard does not purport to address all of the safety problems, 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.
