Description
paper)、再構成タバコのより糸等が挙げられる。例えば、適切なフィルタロッドを提供することができる1種のフィルタ材料は、フィラメント当たり3デニール及び合計40,000デニールを有するセルロースアセテートトウである。別の例として、フィラメント当たり3デニール及び合計35,000デニールを有するセルロースアセテートトウを使用することができる。別の例として、繊維当たり8デニール及び合計40,000デニールを有するセルロースアセテートトウを使用することができる。さらなる例については、Neurathの米国特許第3,424,172号、Cohenらの米国特許第4,811,745号、Hillらの米国特許第4,925,602号、Takegawaらの米国特許第5,225,277号及びArzonicoらの米国特許第5,271,419号(これらの各々はその全体が参照により本明細書に援用される。)に示されているタイプのフィルタ材料を参照されたい。
<ステップA-試験試料の予備調整>
試験試料の予備調整は、使用されている喫煙方式によって異なり得る。例えば、ISO仕様に従って喫煙した試料の予備調整は、試験前の最長10日間までの最低48時間から開始した。予備調整温度は約69.8゜F~約73.4゜Fであり、相対湿度は約50.0~約63.0%の範囲であった。ただし、試験試料が45%未満又は75%超の湿度で保存された場合は、追加試料製品の再調整又は開封が必要であった。同様に、温度が61.6゜F未満又は81.6゜F超過である場合も、追加試料製品の再調整又は開封が必要であった。湿度又は温度が列挙されている範囲内であっても、1時間を超えて仕様から外れていた場合は、追加試料製品の再調整又は開封が必要であった。
タバコの主流煙は、スモークマシーンを用いて実験室環境で収集する。この実験のために、線形スモークマシーン(例えば、セルリーン線形スモークマシーン)を用いて、タバコの主流煙を発生させ、収集した。各試験試料の喫煙された紙巻きたばこの本数は使用した喫煙方式に依存し、一般に約2~約5本の試験用紙巻きたばこであった。
b.)代替喫煙方式。
最初に、2,4-ジニトロフェニルヒドラジン(DNPH)-アルデヒド付加体の濃度が約0.400~約160.00μg/mLの範囲の一連の標準試薬を調製した(表2参照)。
