5. Significance and UseTop Bottom

5.1 This test method was modeled after a procedure commonly known as the Elbow Lean Test.⁸ The Elbow Lean Test involves the application of synthetic blood to an ink pad, placement of sample fabric over the blood soaked pad, placement of a blotter over the sample fabric, and applying elbow or fingertip pressure on top of the blotter. The blotter is then examined for staining as evidence of blood penetration. This test method provides similar procedures which standardize the test equipment and application of pressure through an adopted methodology.

5.2 This test method is intended to simulate actual use conditions wherein areas of the health care worker's protective clothing are soaked with blood and compressed between the patient's body and that of the health care worker, or similarly between the health care worker and instruments. In both cases, unconfined blood can move away from the pressure point taking the path of least resistance rather than being contained as in Test Methods F1670 and F1671.

5.3 This test method uses predominately mechanical pressure as opposed to contained, hydrostatic pressure to demonstrate liquid penetration resistance (1,2) . It simulates a single insult in which the outer surfaces of a protective clothing item are compressed at a steady rate by the wearer's body against a wet surface. This steady rate of compression represents one potential use scenario. Other scenarios may result in a wide variety of pressure ramp rates and profiles that are not simulated by the test apparatus.

5.4 Because this test method provides quantitative results, it is useful for discriminating differences in the liquid barrier performance of protective clothing materials. This test method can be used for measuring differences in the penetration pressure for protective clothing materials which do not pass Test Method F1670.

5.5 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.

5.5.1 Finished items of protective clothing include gloves, arm shields, aprons, gowns, hoods, and boots.

5.5.2 The phrase specimens from finished items encompasses seamed and other discontinuous regions as well as the usual continuous regions of protective clothing items.
