Standard Test Method for Resistance of Materials Used in Protective Clothing to Penetration by Synthetic Blood
SIGNIFICANCE AND USE
5.1 This test method is based on Test Method F903 for measuring resistance of chemical protective clothing materials to penetration by liquids. This test method is normally used to evaluate specimens from individual finished items of protective clothing and individual samples of materials that are candidates for items of protective clothing.
5.1.1 Finished items of protective clothing include gloves, arm shields, aprons, gowns, coveralls, hoods, and boots.
5.1.2 The phrase “specimens from finished items” encompasses seamed and other discontinuous regions as well as the usual continuous regions of protective clothing items.
5.2 Medical protective clothing materials are intended to be a barrier to blood, body fluids, and other potentially infectious materials. Many factors can affect the wetting and penetration characteristics of body fluids, such as surface tension, viscosity, and polarity of the fluid, as well as the structure and relative hydrophilicity or hydrophobicity of the materials. The surface tension range for blood and body fluids (excluding saliva) is approximately 42 to 60 dyn/cm (0.042 to 0.060 N/m) (1).7 To help simulate the wetting characteristics of blood and body fluids, the surface tension of the synthetic blood is adjusted to approximate the lower end of this surface tension range. The resulting surface tension of the synthetic blood is approximately 40 ± 5 dyn/cm (0.040 ± 0.005 N/m).
5.3 The synthetic blood mixture is prepared with a red dye to aid in visual detection and a thickening agent to simulate the flow characteristics of blood.
5.4 Part of the protocol in Procedures A and B in Table 1 for exposing the protective clothing material specimens with synthetic blood involves pressurizing the test cell to 13.8 kPa [2.0 psig]. This hydrostatic pressure has been documented to discriminate between protective clothing material performance and to correlate with visual penetration results that are obtained with a human factors validati...
SCOPE
1.1 This test method is used to evaluate the resistance of materials used in protective clothing to penetration by synthetic blood under conditions of continuous liquid contact. Protective clothing pass/fail determinations are based on visual detection of synthetic blood penetration.
1.1.1 This test method is not always effective in testing protective clothing materials having thick inner liners which readily absorb the synthetic blood.
1.2 This test method is a means for selecting protective clothing materials for subsequent testing with a more sophisticated barrier test as described in Test Method F1671/F1671M.
1.3 This test method does not apply to all forms or conditions of blood-borne pathogen exposure. Users of the test method must review modes for work/clothing exposure and assess the appropriateness of this test method for their specific application.
1.4 This test method addresses only the performance of materials or certain material constructions (for example, seams) used in protective clothing. This test method does not address the design, overall construction and components, or interfaces of garments, or other factors which may affect the overall protection offered by the protective clothing.
1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.
1.6 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.

INTRODUCTION
Workers, primarily those in the healthcare profession involved in treating and caring for individuals
injured or sick, can be exposed to biological liquids capable of transmitting disease. These diseases,
which may be caused by a variety of microorganisms, can pose significant risks to life and health. This
is especially true of blood-borne hepatitis (hepatitis B virus (HBV) and hepatitis C virus (HCV)) and
acquired immune deficiency syndrome (AIDS) (human immunodeficiency viruses (HIV)). Since
engineering controls cannot eliminate all possible exposures, attention is placed on reducing the
potential of direct skin contact through the use of protective clothing that resists penetration (29 CFR
Part 1910.1030). This test method was developed to help assess the effectiveness of materials used in
protective clothing for protecting the wearer against contact with body fluids that potentially contain
blood-borne pathogens. Using synthetic blood, this test method is intended to identify protective
clothing material candidates for further testing according to a more rigorous procedure involving a
surrogate for blood-borne pathogens.
