EDANA 150.3−96に従った、リキッド・ストライク・スルー・タイム(Liquid Strike Through Time)(液体浸透時間)(リスター−テスター(Lister−Tester))
EDANA 151.1−96に従った、カバーストック・リウェット(Coverstock Rewet)(ウェット・バック(Wet Back)とも称する)
クリープ抵抗KBの測定のために、約7×7cm寸法の試験片を打ち抜き、実験室で25時間温度調節した。各3回の個々の測定の算術平均値により決定した。
厚さdを、0.50kPa及び6.2kPaの負荷をかけて測定した。以下の換算式によって、比容積(cm3/g)の値(相対密度の逆数)を得た。
