For CO2, GWP = 1) TSCA Inventory Status — Reported/Included Toxicity AEL * (8- and 12-hr TWA) ppm (v/v) 1,000 * AEL (Acceptable Exposure Limit) is an airborne inhalation exposure limit established by DuPont that specifies time-weighted average concentrations to which nearly all workers may be repeatedly exposed without adverse effects. Note: kPa is absolute pressure. ==External links== * (Physical and chemical properties of 1,1,1,2-Tetrafluoroethane ) 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「1,1,1,2-Tetrafluoroethane (data page)」の詳細全文を読む スポンサード リンク
