Recommendations for Chemical Protective Clothing | NIOSH | CDC- glove breakthrough chart ,Breakthrough (permeation) resistance is related to temperature of the challenge material and the environment and thickness of the barrier. Therefore, higher than normal (25°C) temperatures will result in faster breakthrough. Use of thicker materials will increase time to breakthrough of the chemical.Exam Gloves - Halyard HealthNo breakthrough to 240 minutes Breakthrough detected in 48 minutes Chemotherapy Permeation Testing per ASTM D6978-05 “Standard Practice for Assessment of Resistance of Medical Gloves to Permeation by Chemotherapy Drugs” The following chemicals had NO breakthrough detected up to 240 minutes: Ethidium Bromide, 0.4% Sodium Hydroxide, 40%
