Historical Version s – view previous versions of standard.
Work Item s – proposed revisions of this standard. 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.
The aetm detection technique of this test method is supplemented with a biologically based assay capable of detecting virus under the specified test conditions. Test Method F uses the same penetration test cell and technique, but exposes material specimens to synthetic blood with visual detection of liquid penetration. Materials passing Test Method F should then be tested against bacteriophage penetration using this test method to verify performance.
Inferences about protection from other pathogens must be assessed on a case-by-case basis. This hydrostatic pressure has been documented to discriminate between protective clothing material performance and correlate with visual adtm results that are obtained with a human factors validation 4. Some studies, however, suggest that mechanical pressures exceeding kPa [50 psig] can occur during actual clinical use 56.
Therefore, it is important to understand that this test method does not simulate all the physical stresses and pressures aztm might be exerted on protective clothing materials during actual use. A retaining screen is not used to support the specimen.
Glove directives and norms list
A retaining screen is used to support the specimen. The type must be specified.
Many factors can effect the wetting and penetration characteristics of body fluids, such as: The surface tension range for blood and body fluids excluding saliva is approximately 0.
To help simulate the wetting characteristics of blood and body fluids, the surface tension of the Phi-X Bacteriophage challenge suspension is adjusted to approximate the lower end of this surface tension range. This is accomplished by adding surfactant to the Phi-X Bacteriophage nutrient broth.
The resulting surface tension of the Phi-X Bacteriophage challenge suspension is approximately 0. Additional tests should be considered that assess the impact of storage conditions and shelf life on disposable products and the impact of laundering and sterilization on reusable products.
The integrity of the protective barrier may also be compromised during use by such effects as flexing and abrasion 8. Prewetting agents, such as alcohol, and contaminating agents, such as perspiration, may also compromise the integrity of the protective barrier. If these conditions are of concern, the performance of protective clothing materials should be evaluated for Phi-X Bacteriophage penetration following an appropriate preconditioning technique representative of the expected conditions of use.

Because of the length of time required to complete this method, it may not be suitable for use as a f1761 or protective clothing quality control or quality assurance procedure. Inferences for protection from other pathogens must be assessed on a case-by-case basis. 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.
The values stated in each system must be used independently of the other, without combining values ast, any way. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability v1671 regulatory limitations prior to use.
