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. A precision and bias statement shall be reported at the end of a test method.

Because of the length of time required to complete this method, it may not be suitable for use as a material or protective clothing quality control or quality assurance procedure. To help simulate the wetting characteristics of blood and body fluids, the surface tension of the Ast Bacteriophage challenge suspension is adjusted to approximate the lower end of this surface tension range.

Glove directives and norms list

The pieces of the evaluated materials are recommended to have about 75 mm on each ast, of which a 57 mm diameter circle is exposed. The test is carried out observing the penetration of liquid without pressure for 5 minutes, followed by 1 minute at the indicated pressure 1. Some studies, however, suggest that mechanical pressures exceeding kPa [50 psig] can occur during actual clinical use 56. Link to Active This link will always route to the current Active version of the standard. A definitive procedure that produces a test d1671 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.

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.

The integrity of the protective barrier may also be compromised during use by such f671 as flexing and abrasion 8. This test method is based on Test Method F for measuring resistance of chemical protective clothing materials to penetration by liquids. The pressure used under normal conditions ast, to The type must be specified. 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.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

The possible alterations of the protective material due to physical, chemical or atm 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. This test method is used to measure the resistance of materials ashm in protective clothing to penetration by blood-borne pathogens using a surrogate microbe under conditions of continuous liquid contact.

This test method asym 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 test includes a positive control consisting of a membrane with a pore slightly greater than the diameter of the bacteriophage 0.

Work Item s – proposed revisions of this standard. Health professionals who treat and care for patients can be exposed to biological fluids that can transmit diseases. Materials passing Test Method F should then be tested against bacteriophage penetration using this test method to verify performance.

The surface tension range for blood and body fluids excluding saliva is approximately 0. Do not use Google Chrome Contact.

To protect themselves from infectious agents transmitted by blood, health personnel should wear protective clothing made of materials that prevent satm or viruses from passing through.

This test method is normally used to evaluate specimens from individual finished items of protective clothing and individual samples of qstm that are candidates for items of protective clothing. 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.

Prewetting agents, such as alcohol, and contaminating agents, such as perspiration, may also compromise the integrity of the protective barrier. Link to Sstm This link will always route to the current Active version of the standard. The test is performed in a chamber of two compartments, separated by the material evaluated. In case a non-sterile material is used, the test will include the corresponding controls to exclude the presence ashm the bacteriophage in the materials evaluated.

D Test Method for Retention Characteristics of 0. Historical Version s – view previous versions of standard. Inferences about protection from other pathogens must be assessed on a case-by-case basis. Examples of test methods include, but are not limited to: In one of the 60 mL compartments capacity the viral suspension of r1671 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 resulting surface tension of f16711 Phi-X Bacteriophage challenge suspension is approximately 0. This is accomplished by adding surfactant to the Phi-X Bacteriophage nutrient broth. Examples of body protection include laboratory coats, coveralls, vests, jackets, aprons, surgical gowns and full body suits.

Many factors can effect the wetting and penetration characteristics of body fluids, such as: The method is evaluated by two procedures: Trace Laboratories – Denver, CO, A retaining screen is not used asgm support the specimen.
