The values stated in each system must be used independently of the other, without combining values in any way. Trace Laboratories – Denver, CO, The suspension used to prepare the suspension of bacteriophage use contains 3. Prewetting agents, such as alcohol, and contaminating agents, such as perspiration, may also compromise the integrity of the protective barrier.

The pieces of the evaluated materials are recommended to have about 75 mm on each side, of which a 57 mm diameter circle is exposed.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Examples of test methods include, but are not limited to: The material used in the protective garment will pass or fail in the test, depending on whether it resists penetration is not traversed or allows it to be traversed.
This method is specifically defined for a penetration model of hepatitis B virus, hepatitis C virus and human immunodeficiency virus, atm it is considered by extension that if it resists penetration by these viruses, it will also resist penetration by larger microorganisms like bacteria.
Active view current version of standard.
November 20, Page last updated: 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.
Any visual or virological evidence of penetration will indicate the inability of the material to resist penetration.
These protective garments can be, for asym, gloves, aprons, masks, hoods, or boots, among others. In one of the 60 mL compartments capacity the viral suspension of exposure is introduced, containing the bacteriophage Phi-X and in the opposite compartment the appearance of liquid or the presence of the virus is detected. The surface tension range for blood and body fluids excluding saliva is approximately 0. To perform the method, samples of the materials are exposed to a nutrient broth containing the bacteriophage virus Phi-X, as a virus surrogated by its characteristics similar in size to the hepatitis C virus, and by extension to the hepatitis B virus and of human immunodeficiency virus these viruses are not used because of their difficulty to be cultured in laboratories.

This hydrostatic pressure has been documented to discriminate between protective clothing material performance and correlate with visual penetration results that are obtained with a human factors d1671 4. A precision and bias statement shall be reported at the end of a test method. Test Method A definitive procedure that produces a test result: This includes bullet-proof clothing, general protective clothing and full body ensembles that protect from cuts, radiation, temperature extremes, hot splashes from molten metals and other hot liquids, potential impacts from tools, machinery and materials and hazardous chemicals.
This test method is based on Test Method F for measuring resistance of chemical protective clothing materials to penetration by liquids. November 20, Content source: The exposure is carried out for a specified time and under a selected pressure. This test method does not asmt 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 integrity of the protective barrier may also be compromised during use by such effects as flexing and abrasion 8. These diseases can be caused by a wide variety of microorganisms and can pose a significant risk to health and life. Inferences for protection from other pathogens must be assessed on a case-by-case basis. This standard does not purport to address all of the safety concerns, if any, associated with its use.
The method is evaluated by two procedures: Inferences about protection from other pathogens must be assessed on a case-by-case basis. The manufacturer must indicate the possibility that the material under test can be altered by thermal treatment wet sterilizationso as not to do so in the event that it can be altered.
The type must be specified. Additional tests should be considered qstm assess the impact of storage conditions and shelf life on disposable products and the impact of laundering and sterilization on reusable products.
Historical Version s – view previous versions of standard. Therefore, it is important to understand that this test method does not simulate all the physical stresses and pressures that might be exerted on protective clothing materials during actual use.
Work Item s – proposed revisions of this standard. D Test Method for Retention Characteristics of 0. A retaining screen is not used to support the specimen. 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.
The test is performed in a chamber of two compartments, separated by the material evaluated. This method is not effective for testing protective clothing materials that are internally coated by a thick coating that can absorb the astk containing the test virus.
The method described in these standards, evaluates the effectiveness of materials used in the manufacture of protective garments against bloodborne pathogens using a surrogate virus suspended in a liquid, simulating the spontaneous contact conditions in a sanitary environment.
Link to Active This link will always route to the current Active version of the standard. The resulting surface tension of the Phi-X Bacteriophage challenge suspension is approximately 0. Clothing for protection against contact with blood and body fluids — Determination of resistance of protective clothing materials to penetration by blood-borne pathogens – Test method using Phi-X bacteriophage.

This is accomplished by adding surfactant to the Phi-X Bacteriophage nutrient broth.

Test not accredited in our laboratory. Asym possible alterations of the protective material due to astk, chemical or thermal effects should be taken into account, since in this case they would negatively influence the behavior of the material, so that in case it can occur, the tests should be carried out before exposures to such material, physical, chemical or thermal conditions that may deteriorate it. D Test Method for Retention Characteristics of 0.
The values stated in each system must be used independently of the other, without combining values in any way.
