You must scarcely pass a combustible examination of association of Japan railroad carriage machine technology to have you use our flaming retardant wood, lucky sign cedar as materials for the railroad carriage.

As for this, an original standard is established and is that a hurdle is expensive more than the examination using the general corn calorimeter. The number of the examination bodies to prepare, the size is different. (as for the corn calorimeter about 1 examination at 100mm *100mm as for two pieces, this examination about 1 examination at B5 size four pieces)

I do not yet know it, but just pray for how a result turns out this time as it is the first challenge heartily when I want you to pass it.
