(式中、GはASTM D646−96(再認可2001)により求め、1平方メートル当たりのグラム(g/m2)で表した多層シートの坪量である);および
S≧2×10-7G3.1872 (1c)
(式中、Sは関係:
S=(SmSc)0.5 (1d)
(式中、Smは、ドイツ工業規格(DIN)DIN53121:1996−12で述べられている二点法で求められ、ミリニュートンメートル(mNm)で表した、多層シートの面内の最大曲げモーメントであり、Scは、この多層シートの面内のSmの測定で選択された方向に垂直に測定し、ミリニュートンメートル(mNm)で表した、曲げモーメントであり、DIN53121:1996−12で述べられている二点法で求められる

を充たす。
S=(SmSc)0.5 (1d)
(式中、Smは、DIN53121:1996 12で述べられている二点法で測定され、ミリニュートンメートル(mNm)で表した、多層シートの面における最大曲げモーメントである)
から計算し、ミリニュートンメートル(mNm)で表した、この積層シートの幾何平均曲げモーメントである。
1.この試験をDIN53121:1996 12の図1(Bild1)に図示されている回転クランプ付きの試験装置上で行う。
2.試験対象の多層シートの試料を50ミリメートルの長さおよび38ミリメートルの幅に切断する。
