(遠心後の試料/バッグ−遠心後の空のバッグ−乾燥試料重量)/乾燥試料重量
シリンダー、ピストン(4.4g)、標準おもり(317g)を含むAULアセンブリ。アセンブリの要素の詳細は後述する。
トレー壁と接触することなく底部にガラスフリットを置くことができる幅を有する正方形の平底プラスチックトレー。寸法が9×9インチ(22.9×22.9cm)であり、深さが0.5〜1インチ(1.3〜2.5cm)のプラスチックトレーをこの試験法において通常使用する。
直径12.5cmの「C」気孔率(25〜50μm)を有する焼成ガラスフリット。フリットは、食塩水(0.9重量%塩化ナトリウム蒸留水溶液)内で平衡化して予め準備する。少なくとも2つの部分を食塩水で洗浄し、フリットはAUL測定前に少なくとも12時間にわたって食塩水に浸漬する。
Whatman Grade 1 円形ろ紙(直径:12.5cm)。
食塩水(0.9重量%塩化ナトリウム蒸留水溶液)の供給。
