本标准规定了无机硬质绝热制品几何尺寸、外观质量、抗压强度、密度、吸水率、含水率、均温灼烧性能等项目的试验方法。本标准代替ＧＢ／Ｔ５４８６．１—２００１《无机硬质绝热制品试验方法　外观质量》、ＧＢ／Ｔ５４８６．２—２００１《无机硬质绝热制品试验方法　力学性能》、ＧＢ／Ｔ５４８６．３—２００１《无机硬质绝热制品试验方法　密度、含水率及吸水率》、ＧＢ／Ｔ５４８６．４—２００１《无机硬质绝热制品试验方法　匀温灼烧性能》。
本标准与ＧＢ／Ｔ５４８６．１～５４８６．４—２００１相比主要变化如下：
———增加了弧形板和管壳抗压强度受压面最小尺寸；
———修改了抗压强度、抗折强度试件数量；
———修改了匀温灼烧性能的升温速率与恒温时间。
