ASTM F1407- 12, published by the American Society for Testing and Materials (ASTM), describes a test method for determining the chemical resistance of protective clothing material samples. The full name of this standard is as follows: ASTM F1407-12 Standard test method for the resistance of chemical protective clothing materials to liquid permeability - Permeable container method.
The test method presented in the said standard provides a test method for determining the resistance of materials used in the production of protective clothing to chemical substances in one hour or less.
Detection time, permeation rate or cumulative permeability values are used to identify protective clothing items that are more likely to limit exposure to potential chemicals. Longer permeation detection times and lower cumulative amounts and penetration rates are characteristics of materials that are better barrier to chemicals.
In general, the test method included in this standard is less sensitive than the test method presented in the ASTM F739 standard with precision analytical procedures. The permeable container method is not recommended in cases where the chemical substance in question is highly toxic and even a small amount will be harmful in contact with the skin.
After penetrating the garment material, the chemical must evaporate during the test in order to lose weight and to detect penetration. In short, the permeable container test method does not apply to chemicals with low volatility, ie vapor pressure. But huhIt has not been specified in the standard that this test method cannot be applied under ngi vapor pressure.
The results of this test method are highly dependent on the test temperature. If this test method is to be used to compare different clothing items, all tests must be carried out at the same temperature.
In short, this test method determines the barrier effectiveness when a protective garment is in constant contact with a liquid.
With the experience gained over many years, our organization also provides standard test (permeable container method) services for the resistance of ASTM F1407-12 chemical protective clothing materials to liquid permeability within the framework of laboratory services of the materials with a trained and expert staff.
