Chemical Permeation. Permeation resistance testing measures the rate at which chemicals pass through the material on a molecular level. When tested in accordance with ASTM F739-12, the glove’s chemical permeation is classified according to the levels shown below, using the average standard breakthrough time (for each chemical tested):

CHEMICAL GLOVE SELECTION - Ansell

Permeation breakthrough time is a theoretical indication of how long it takes a chemical to permeate a glove. It should be used to make a distinction between glove materials and thickness rather than interpreted as total usage time. Look at the other aspects of the application aside of chemicals (abrasion, tear, heat resistance, antistaticity,

1. Breakthrough Detection Time (BTT): the time in minutes after initial exposure of a chemical to the outer surface of the glove material to the time it can first be detected on the inside of glove. BTTs reported are normalized to a permeation rate of 0.1 µg/cm2/min. All BTTs meet this requirement except those analyzed by pH or conductivity.

Gloves for Handling Pesticides

Breakthrough time, the length of time it takes for the pes-ticide to permeate the glove, is generally longer the thicker the material. A material’s breakthrough time will be shorter when exposed to concentrated pesticides as opposed to diluted pesticides, but even so, the thicker material will offer protection longer.

Increasing the thickness of a glove will normally increase the time to breakthrough, but the benefits may be offset by a decrease in tactility and dexterity. Thus use of multiple layers (e.g. double gloving) can increase thickness and provide properties of different materials. Gloves should be at least 0.3 mm thick. 6. Protective gloves and ...
