Chemical Resistance Chart

1 1 Chemical Resistance ChartASTM Breakthrough Times in Minutes and ISEA/CE ratings for Best GlovesExplanation of RatingsBTT or Breakthrough times are given in minutes and represent theNormalized breakthrough times required by ASTM F 739-96 Methodfor Permeation. The ratings are a part of the ANSI/ISEA 105-2000 American National Standard for Hand Protection Selection ratings range from 0 to 6 with 6 being the best Resistance Ratings0< 10 minute breakthrough time1 10 minute breakthrough time2 30 minute breakthrough time3 60 minute breakthrough time4 120 minute breakthrough time5 240 minute breakthrough time6 480 minute breakthrough timeChemical by ClassNeopreneNitrileRubberPVCB utylViton*Aliphatic SolventsBTT RatingBTT RatingBTT RatingBTT RatingBTT RatingBTT Rating1.
