Standard Test Method for Resistance of Materials Used in Protective Clothing to Penetration by Liquids
SIGNIFICANCE AND USE
5.1 This test method is normally used to evaluate the barrier effectiveness against penetration of liquids through materials, seams, closures, or other planar assemblies used in protective clothing and specimens from finished items of protective clothing.
5.1.1 Finished items of protective clothing include gloves, arm protectors, aprons, coveralls, suits, hoods, boots, and similar items.
5.1.2 The phrase “specimens from finished items” is permitted to include continuous regions of protective clothing items as well as seamed or other discontinuous regions of protective clothing.
5.1.3 The types of specimens are limited to those that are relatively flat (planar) that are capable of being sealed in the test cell specified in this test method without peripheral leakage.
5.2 A substitute challenge liquid (for example, water or isopropanol) is appropriate in some cases to generalize material penetration resistance to liquids. However, it is possible that differences in chemical and molecular properties (for example, surface tension) may lead to different results.
5.3 In addition to the failure mode where a liquid finds a pathway for penetration through a void, imperfection, or defect in material or clothing subassembly, some selected chemicals cause degradation of barrier material, film, or coating, leading to penetration over extended periods of contact.7
5.4 Five different procedures for how the specimen is exposed to the liquid are provided in Table 1. In this test method, all procedures involve liquid exposure that is continuous over the duration of the test. These procedures entail different hydrostatic pressures and durations of liquid exposure.
5.4.1 Procedures A, B, and C apply a set pressure (6.9 or 13.8 kPa [1 or 2 psig]) for a specified period of time (1 or 10 min) over a 15- or 60-min liquid exposure time.
5.4.2 Procedures A and B represent the originally established methods of liquid contact developed by the National Institute for Occu...
SCOPE
1.1 This 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.
1.2 This 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.
1.3 In 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.
1.4 This test method does not address penetration of vapors through protective clothing materials.
1.5 This test method is not applicable to non-planar protective clothing materials, interfaces, or assemblies such as the fingertips or crotch areas of gloves, which are possible failure points.
1.6 This test method does not address the liquid penetration resistance of full protective clothing items or ensembles. Use Test Method F1359 for this purpose.
1.7 The values as stated in inch-pound units are to be regarded as the standard. The values in parentheses are for information only.
1.8 This 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific hazards are given in Section 7.

INTRODUCTION
Workers involved in the production, use, and transportation of liquid chemicals can be exposed to
numerous compounds capable of causing harm upon contact with the human body. The deleterious
effects of these chemicals can range from acute trauma such as skin irritation and burn, to chronic
degenerative disease such as cancer. Since engineering controls may not eliminate all possible
exposures, attention is often placed on reducing the potential for direct skin contact through the use
of protective clothing that resists permeation, penetration, and degradation.
This test method determines resistance of protective clothing materials, seams, and closures to
