本标准重申了2000年发布的T 461 cm-00。本程序描述了一种测试不超过1.6mm（0.063 in.）的纸张和纸板阻燃性的方法经过处理以防止点燃时火焰蔓延的厚度。它还提供了一个质量和实用性参数，通过区分具有非耐久性处理（通过水浸去除）的纸或纸板（指定为I型）和具有耐久性处理（通过水浸去除）的纸或纸板（指定为II型）。安全预防措施。本试验方法测量规定试验条件下的阻燃性。 用户必须对预测特定纸张最终用途的适用性做出任何判断。本试验方法并非旨在解决与其使用相关的所有安全问题。本方法的使用者有责任在使用前建立适当的安全和健康实践，并确定监管限制的适用性。应特别注意所用气体的材料安全数据表（MSDS）和3.3中燃烧器的使用手册。

This standard reaffirms T 461 cm-00, published in 2000.This procedure describes a method for testing the flame resistance of paper and paperboard not over 1.6mm (0.063 in.) in thickness that have 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.
