1998年，日本修订了《建筑标准法》，强调以性能为基础的法规，而不是传统上符合规范的规定。还改变了阻燃材料的评价方法，采用锥形量热计试验。虽然含磷、含氮的化学试剂被广泛用于制造阻燃木材，但很少有锥形量热仪测试结果表明阻燃剂的浸渍量与其性能之间的关系。在本研究中，以聚磷氨基甲酸酯为主要成分的商品阻燃剂浸渍在15 mm厚的日本红松试件中，并用锥形量热仪测试其燃烧性能。当浸渍阻燃剂大于80 kg/m3时，试件表现出阻燃材料的性能。当阻燃剂用量大于160 kg/m3时，试件达到准不可燃材料标准。然而，将经过化学处理的材料放置在人们可以触摸的表面并不总是可取的。用锥形量热仪测试了表面覆盖未处理单板的木材试件的阻燃性能。当单板厚度为0.5 mm(230g/m2重量)时，试件的耐火性能指标保持不变。
In 1998, the Building Standard Law of Japan was revised to emphasize performance-based regulations rather than conventional conformity to specifications. The method of evaluating fire-retardant material was also changed and the cone calorimeter test was adopted. Although chemical agents that contain phosphorus and nitrogen are widely used to make fire-retardant wood, there are few results of cone calorimeter tests to show the relationship between impregnated quantity of fire retardant and its performance. In this study, a commercial fire retardant whose main component is poly-phosphatic carbamate was impregnated in a 15-mm-thick Japanese red pine specimen, and the fire performance was tested by the cone calorimeter test. When the impregnated fire retardant was over 80 kg/m 3 , specimens showed the performance of fire-retardant material. When there was more than 160 kg/m 3 of fire retardant, specimens met the criteria of quasi-noncombustible materials. However, it is not always desirable to put chemically treated materials on the surface where people can touch. The fire-retardant properties of wood specimens whose surface was covered with untreated veneer were also tested by the cone calorimeter. When the thickness of the veneer was 0.5 mm (230 g/m 2 in weight), the fire-performance criterion of the specimen remained the same.
