fpullは、「張力帯」として画成されるおむつの一部分を引張る力(cNで測定される)であり、
f(c)は、cの無次元関数(dimensionless function)で、単調増加し、それはc=0に関して小さく、
cは、引張り力が印加される場所を示す繋止点パラメータであり、
Tは、おむつ「張力帯」における張力(cNで測定される)であり、
wは、おむつ「張力帯」の幅(cmで測定される)であり、
rは、バンド平面に沿った曲率半径(cmで測定される)であり、
cfrは、おむつ材料の摩擦係数であり、及び

使い捨て吸収性物品の曲げ抵抗をピーク曲がり剛性により測定する。ピーク曲がり剛性は、ASTM D4032−82円形曲げ手順(Modified Circular Bend Procedure)後にモデル化された試験によって測定され、その手順を大幅に修正し以下のように実施した。修正円形曲げ手順(以降、「手順」)は、材料の同時多方向変形であり、試験片の1つの面が凹状となり、もう1つの面が凸状となる。手順は、曲げ抵抗に関連した抵抗力値を与え、同時に全ての方向の剛性を平均する。
1. 18.75ミリメートル直径のオリフィスを有する102.0×102.0×6.35ミリメートルである平滑に磨かれた鋼プレートプラットホーム。オリフィスの重ね縁部は、4.75ミリメートルの深さに対して45度角でなければならない。
2. 全長72.2ミリメートル、直径6.25ミリメートルを有するプランジャ、半径2.97ミリメートルを有するボールノーズ、そこから0.88ミリメートル延伸し0.33ミリメートルベース直径を有するニードルポイント及び0.5ミリメートル未満の半径を有するポイントを有するプランジャであって、該プランジャは、オリフィスと同心に装着され全ての側に等しいすきまを有する。尚、ニードルポイントは、試験時に試験片の横方向移動を単に防止するためだけのものである。従って、ニードルポイントが有意に試験試験片に悪影響を及ぼす場合(例えば、膨張性構造体に穴を開ける)、その時には(than)ニードルポイントを使用すべきでない。プランジャの底部は、オリフィスプレートの上部に確実に取り付けなければならない。この位置から、ボールノーズの下方ストロークは、正確にプレートオリフィスの底部までである。
3. 抵抗力測定計、より具体的にはインストロン逆圧縮ロードセル。ロードセルは、約0.0〜約2,000.0グラムの荷重範囲を有する。
4. 作動装置、より具体的には逆圧縮ロードセルを有するインストロンモデル番号1122。インストロン1122は、マサチュセッツ州カントン(Canton)のインストロン・エンジニアリング社(Instron Engineering Corporation)により製造される。
