Abstract
Description
20分浸出値は、次の20分浸出値試験方法を用いて測定される。円形ダイツールを用いておむつのバックシート材料から38mm直径の円形部分を切り抜く。バックシート材料の非限定例は、米国ヴァージニア州リッチモンド(Richmond)のトレデガー・インダストリーズ(Tredegar Industries)から市販されているような1平方メートルあたり37グラムの坪量を有するミクロ孔質ポリエチレンである。このブランク円形バックシート試料を化学てんびんで正確に少なくとも小数点以下第4位まで計量する。この重量を記録する。
1時間浸出値試験は、調製された試料を20.0グラムの合成尿に20分ではなく全部で1時間曝す以外、20分浸出値試験方法と同一である。1時間の浸出値は、合成尿20.0グラムに1時間曝露するの間に湿潤指示体1グラムあたりから浸出する着色剤のマイクログラムとして定義される。
3時間浸出値試験は、調製された試料を20.0グラムの合成尿に20分ではなく全部で3時間曝す以外、20分浸出値試験方法と同一である。3時間の浸出値は、合成尿20.0グラムに3時間曝露する間に湿潤指示体1グラムあたりから浸出する着色剤のマイクログラムとして定義される。
14時間浸出値試験は、調製された試料を20.0グラムの合成尿に20分ではなく全部で14時間曝す以外、20分浸出値試験方法と同一である。14時間の浸出値は、合成尿20.0グラムに14時間曝露する間に湿潤指示体1グラムあたりから浸出する着色剤のマイクログラムとして定義される。
