ASTM C 1166: 密致及多孔弹性体衬垫和附件火焰蔓延的试验方法

ASTM C 1166: Standard test method for flame propagation of dense and cellular elastomeric gaskets and accessories. 密致及多孔弹性体衬垫和附件火焰蔓延的试验方法。

Calculate the average flame propagation (FP) for R1through R6 according to the following equation:

FP= ([R1_o-R1 _f]+ [R2_o-R2_f] +[R3_o-R3_f]+ [R4_o-R4_f] +[R5_o-R5_f] +[R6_o-R6_f]) / 6

Where:

R1_o=original R1

R1 _f= final R1

R2_o=original R2

R2 _f= final R2

此测试方法被引用于NFPA130弹性体衬垫和附件的防火性能测试部分。

Average flame propagation shall be less than 101.6mm (4 in), and no specimen shall be completely consumed.
