・NIST、DIN、JIS又はその他の同等の国家規格まで追跡可能な金属定規
・内側が平らな表面であり、測定されるコアバッグの長さの最小長が(n)及び最大長が(n)+30mm、幅が105±5mm、高さが30〜80mm、又はその等価である、PVC/金属皿
・電子フォースゲージ(0〜50kgの範囲)

標準実験室条件、温度:23℃±2℃、相対湿度:55%未満
試料の調製
1.トップシート側を上にして、製品を開ける。
2.おむつを広げ、およそ2.5cm毎にカフの弾性体を切って、シャーシの張力を無効にする。
3.プルアップ製品に関しては、サイドシームを開け、ウエストバンドを取り除く。
4.コアバッグを平らに長方形のトップシート側を上にして折り目なしにライトボックスの表面上に置く。
5.ライトボックスをオンにして、吸収性コアの外側縁部を明確に特定する。
6.定規を用いて、前部吸収性コア外側縁部及び後部吸収性コア外側縁部で線を引く。
7.2つの標線の間の距離(A)を測り、その値を2で割ると、距離(B)が計算される。
8.前部標線からコアバッグの中央に向かって、計算された距離(B)を測り、印をつける。この標線で横断方向に線を引く。
WAIIT較正:
1.スライド板が下部位置にあることを確認する。WAIIT試験機の前扉を開き、フォースゲージのフックをWAIITの上部サンプルクランプに接続させる。ばね秤を接続する前に、クランプが閉じていることを確認する。
2.ばね秤に両手を使って、スライド板を上部位置に向かって継続的に、またできるだけゆっくりと持ち上げる。実行中の平均値(m1)を0.02kg単位で記録する。
3.スライド板を下部位置までできるだけゆっくりと下ろし、実行中に読み取られた平均値(m2)を0.02kg単位で記録する。
4.m1〜m2のΔを計算し、0.01kgの単位で報告する。Δが0.6kg±0.3kgであるなら、測定を継続する。そうでない場合は、スライド板の調整が必要である。スライド板が下部位置にあることを確認し、汚染又は損傷に関してスライド通路を点検する。スライド通路に対するスライド板の位置が正しく調節されているかどうかを、板を振動させることによって点検する。容易な滑走のためには、いくらかの隙間が必要である。もしなければ、システムを再調整する。
・落高は50cmである。
・おむつの負荷(lD)はコア容量(cc)の73%である;lD=0.73×cc。
・コア容量(cc)は、cc=mSAP×SAPGVとして計算され、式中、mSAPは、おむつに存在する超吸収性ポリマー(SAP)の質量であり、SAPGVは、超吸収性ポリマーの自由膨潤容量である。超吸収性ポリマーの自由膨潤容量は、国際公開第2006/062258号に記載の方法で求められる。おむつに存在する超吸収性ポリマーの質量は、10個の製品に存在する平均質量である。
1.はかりを0にリセットし(風袋)、乾燥コアバッグをはかりに載せ、計量し0.1g単位で報告する。
2.メスシリンダーで適切な量の生理食塩水(脱イオン水中0.9%NaCl)を計る。
3.コアバッグをトップシート側を上にして平らにPVC皿内に置く。生理食塩水を均等にコアバッグの上に注ぐ。
4.PVC皿を取り、様々な方向に傾けて保持して、遊離した液体を吸収させる。ポリバックシートを有する製品は、バックシート下の液体が吸収されることができるように、2分間の最低待機時間後にひっくり返す必要がある。10分間(±1分間)待機して生理食塩水全てを吸収させる。何滴かはPVC皿に留まってもよい。均質の液体分配及びより少ない保留液体を確実にするために、規定されたPVC/金属皿のみを使用する。
5.はかりを0にリセットし(風袋)、湿潤したコアバッグをはかりに載せる。計量し0.1g単位で報告する。はかり上に納まるように、コアバッグを1回だけ折る。湿潤したコアバッグの重量が限界(「乾燥コアバッグの重量+おむつの負荷±4mL」として規定)外かどうかを確かめる。例えば、12gの乾燥コアバッグの重量+150mL負荷=162gの湿潤したコアバッグの重量。はかり上の実際の湿潤重量が、158gと166gの間であるなら、そのパッドを振動に使用することができる。そうでなければ、そのパッドを廃棄し、次のパッドを使用する。
6.負荷されたコアバッグを取り、標線に沿って横断方向に切る。
7.湿潤したコアバッグの後部をはかりの上に載せる(m1)。計量し0.1g単位で報告する。
8.湿潤したコアを取り、末端封止側をWAIITのサンプルホルダーの上部クランプに固定する(コアの開放端は下に向く)。次に、製品が製品の全長に沿ってサンプルホルダーに固定されていることを確認しながら、コアの両側をサンプルホルダーの側部クランプで固定する。吸収性コア(不織布のみ)を固定しないよう確認するが、それは、一部の製品に関して、バリアレッグカフのみで製品を固定することを意味するためである。
9.スライド板が係合するまで、両手を使うことにより、スライド板を上部位置まで持ち上げる。
10.安全前扉を閉め、スライドブレードを解放する。
11.はかりを0にリセットし(風袋)、試験されたコアバッグをWAIITから取り出し、はかりに載せる(m2)。重量を0.1g単位で報告する。
12.工程7〜11を湿潤したコアバッグの前部で繰り返す。
1.乾燥コアバッグの重量を0.1g単位で記録する。
2.試験前(m1前部/後部)及び試験後(m2前部/後部)の湿潤重量を両方とも0.1g単位で記録する。
3.平均重量損失(Δm)をパーセントで計算し、1%単位で報告する:Δm=(m1前部+m1後部)−(m2前部+m2後部)
4.重量損失(Δmrel)をパーセントで計算し、1%単位で報告する:(Δmrel)=(((m1前部+m1後部)−(m2前部+m2後部))×100)/(m1前部+m1後部)
5.湿潤時固定化(WI)をWI=100%−Δmrelとして計算し報告する。
