在《防火门》GB12955-2008中只对钢质防火门所使用的门扇面板厚度有所规定,要求门扇面板厚≥0.8mm.

But there is no regulation on the thickness of the fire door.
但防火门厚度恰没有规定。

Fire doors can be divided into Class A fire doors, class B fire doors and class C fire doors according to the fire resistance time limit.
防火门根据耐火时限可以分为甲级防火门、乙级防火门、丙级防火门。

The fire resistance time limit of Class A fire door is 1.5h, and as long as the fire door meets this condition, it can be called Class A fire door.
甲级防火门的耐火时限为1.5h,只要满足这个条件的防火门,都可以叫做甲级防火门。

The filling material inside the Class A fire door is generally perlite, the difference is only the thickness is different, and the individual will also use the foam door core board, vermiculite fire retardant board, MC composite materials and so on.
甲级防火门里面的填充材料一般采用珍珠岩,区别只是厚度不同,个别也会采用发泡门芯板、蛭石防火板、MC复合材料等等防火材料。

Each fire door manufacturer is in the raw material procurement, production process, cost accounting and other considerations, grade A fire door design door thickness is not the same.
各个防火门厂家处于原材料采购、制作工艺、成本核算等考虑,甲级防火门设计的门扇厚度也是不一样的。

At present, the popular fire door core in the market is generally 48mm thick, so the Class A fire door is generally 50mm.
目前市场流行的防火门芯一般是48mm厚的,所以甲级防火门一般是在50mm。
