The ASTM F739-12 standard, published by the American Society for Testing and Materials (ASTM), describes the properties and test methods for the passage of liquids and gases through protective clothing materials under continuous contact conditions. The full name of this standard is as follows: ASTM F739-12 Standard test method for the permeability of liquids and gases through protective clothing materials under continuous contact conditions.
The test method presented in this standard is designed to be used when the test chemical is a gas or liquid and that liquid is volatile or soluble in water, or another liquid that does not interact with the garment material. The chemical gas or liquid described herein is a chemical gas or liquid with a vapor pressure higher than 25 mm mercury at 1 degrees. One millimeter of mercury is the extra pressure created by a one-millimeter-high column of mercury.
This standard does not take into account safety concerns for use. It is the responsibility of the enterprise implementing this standard to establish appropriate safety, health and environmental practices and to comply with the limits imposed by legal regulations before use.
This test method is normally used to evaluate finished pieces of protective clothing or materials to be used for this purpose. By means of completed protective clothing parts, gloves, arm sleeves, aprons, clothes, hats, boots, respirators and similar parts are expressed. These materials are evaluated in terms of permeability detection time, standard transition time, permeability rate and cumulative permeability values. These data are used for the comparison of clothing materials in the process of clothing selection to protect against hazardous chemicals. Long detection times, low cumulative permeation and low permeation rates are the main features sought.
The test method included in the ASTM F739-12 standard is also part of the ISO 6529 standard published by the International Organization for Standardization (ISO).
With the experience gained over many years, our organization also provides standard testing services for the permeability of liquids and gases through protective clothing materials under ASTM F739-12 continuous contact conditions, within the framework of laboratory services of the materials with a trained and expert staff.Inhibitory.
