Full Description

1.1This test method is used to test specimens of protective clothing materials, assemblies such as seams and closures, or interfaces used in the construction of protective clothing. The resistance to visible penetration of the test liquid is determined with the liquid in continuous contact with the normally outside (exterior) surface of the test specimen.

1.2This test method includes different procedures for maintaining the liquid in contact with the test specimen in terms of the length of exposure and the pressure applied. Suggestions are provided for how to select an appropriate procedure for liquid contact.

1.3In some cases, significant amounts of hazardous materials will permeate specimens that pass the penetration tests. For more sensitive analyses use either Test Method F739 or F1383 to determine permeation.

1.4This test method does not address penetration of vapors through protective clothing materials.

1.5This test method is not applicable to non-planar protective clothing materials, interfaces, or assemblies such as the finger tips or crotch areas of gloves, which are possible failure points.

1.6This test method does not address the liquid penetration resistance of full protective clothing items or ensembles. Use Test Method F1359 for this purpose.

1.7The values as stated in inch-pound units are to be regarded as the standard. The values in parentheses are for information only.

1.8This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific hazards are given in Section 7.
