Fabric Permeation & Penetration Data

It is imperative to select protective garments that prevent workers from being exposed to chemical hazards in your work environments. The test results provided have been conducted by an independent laboratory in accordance with either the ASTM F739 (Permeation) or ASTM F903 (Penetration) standards.

Permeation (ASTM F739)

Permeation Testing is conducted in accordance with ASTM F739 – “Standard Test Method for Permeation of Liquids and Gases through Protective Clothing Materials under Conditions of Continuous Contact”. This test will determine how effective a fabric is at providing a barrier from challenge chemicals on a molecular level. The results are stated in the amount of time it takes the chemical to diffuse through the fabric during continuous contact. “Breakthrough” is the amount of time it takes the challenge chemical to permeate through the fabric and is expressed in minutes.

Tests are conducted in various chemical states i.e. (G = Gas, L = Liquid, M = Mixture, S = Solid). The results are expressed in the amount of time it takes for the chemical to pass through the fabric. We report the Average Normalized Breakthrough Time – in accordance to the ASTM F739 standard. Results shown as >480 indicate that the chemical did not permeate the fabric during the 480 minute test duration.
