It is technically possible for this test method to yield both false-positive and false-negative results, or for a fabric that gives an adequate degree of protection against blood or body fluid

The

17、 work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-gove

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. T

19、he main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.

21、quipment, Subcommittee SC 13, Protective clothing. It is based on ASTM F1670-98. BSISO16603:2004 vIntroduction Workers, primarily those in the health care profession, involved in treating and caring for individuals injured or sick, can be exposed to biological liquids capable of transmitting disease

22、. 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 viruses which cause hepatitis hepatitis B virus (HBV) and hepatitis C virus (HCV) and acquired immune deficiency syndrome (AIDS) human immunodef

23、iciency 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. This International Standard is concerned with protective clothing and related protective devices des

24、igned to protect against the penetration of blood or body fluids. This test method addresses only the performance of materials or certain material constructions (e.g. seams) used in protective clothing. This test method does not address the design, overall construction and components, or interfaces

25、of garments or other factors which can affect the overall protection offered by the protective clothing. It is emphasized that the test does not necessarily simulate conditions to which clothing materials are likely to be exposed in practice. The use of test data should therefore be restricted to br

26、oad comparative assessment of such material according to their synthetic blood penetration resistance characteristics. Testing prior to degradation by physical, chemical, and thermal stresses which could negatively impact the performance of the protective barrier, could lead to a false sense of secu

27、rity. Tests which assess the impact of storage conditions and shelf life on the penetration resistance for disposable products, and the effects of laundering and sterilization on the penetration resistance for reusable products, should be considered. The integrity of the protective barrier can also

28、be compromised during use by such effects as flexing and abrasion or pre-wetting by contaminating materials such as alcohol and perspiration. If these conditions are of concern, the performance of protective clothing materials for synthetic blood penetration should be evaluated following an appropri

29、ate preconditioning technique representative of the expected conditions of use. Medical protective clothing materials are intended to be a barrier to blood, body fluids, and other potentially infectious materials. Many factors can effect the wetting and penetration characteristics of body fluids, su

30、ch 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 0,042 N/m to 0,060 N/m. 2In order to help simulate the wetting

31、 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, i.e. (0,042 0,002) N/m. Part of this method for exposing the protective clothing material specimens with synthetic blood involves pressurizati

32、on of the test cell to 14,0 kPa (in Procedures A and B). This hydrostatic pressure has been documented to produce test results that correlate with a human factors validation. 3Some studies, however, suggest that mechanical pressures exceeding 345 kPa can occur during actual use. 4 5Therefore, it is

33、important to understand that this test method does not simulate all the physical stresses and pressures that are exerted on protective clothing in use. This test method can also be used as a screening test to determine which time and pressure protocol is appropriate for evaluating the viral-resistan

34、ce-properties of protective apparel with a more sophisticated barrier test method as described in ISO 16604. Procedures C and D use a stepped pressurization approach with pressures up to 20,0 kPa. These procedures simulate a range of possible procedures for ranking material performance. Given the va

35、riety of health care settings, activities, and the potential for exposure to blood or body fluids, the barrier requirements for protective clothing materials will change with the application. The choice of an appropriate test method depends on the specific application of protective clothing and its

36、intended use. A risk assessment should be performed to determine the level of risk for determining the appropriate test method. 1BSISO16603:2004blankINTENRATIONAL TSANDADR IS:30661 O4002(E)1Clothing for protection against contact with blood and body fluids Determination of the resistance of protecti

This test method is not always effective in testing protective clothing materials having thick, inner liners which readily absorb the synthetic blood. 2 Normative references The following

In the penetration test apparatus, the clothing material acts as a partition separating the body fluid simulant from the viewing side of the test cell. Any eviden

Results are reported as “pass/fail”. 5 Synthetic blood The synthetic blood shall meet the following requirements: surface tension: (0,042 0,002) N/m pH: (7,3 0,1) viscosity: (2,7 0,3) mPas conductivity: (12,0 1,2) mS/cm NOTE A suitable method of preparation can be found in Annex A.
