3、sed to numerous liquids capable ofcausing harm upon contact with the human body. These liquids may include chemicals, contaminatedblood or body fluids, and other hazardous liquids. The deleterious effects of different chemicals canrange from acute trauma such as skin irritation and burn, to chronic

4、degenerative disease such ascancer. Biological-based hazard liquids may include various liquidborne pathogens capable of causinginfection directly or with non-intact skin. Since engineering controls cannot eliminate all possibleexposures, attention is often placed on reducing the potential for direc

5、t skin contact through the useof protective clothing.Protective clothing is available in a variety of constructions, configurations, and materials, and isdesigned to provide various levels of protection against many hazards. Protective clothing offering thehighest level of chemical protection is con

6、structed to prevent any contact of solid, liquid, or gaseouschemicals with the wearer. Test Method F1052 evaluates the integrity and construction of the vaporprotective ensembles by way of an internal pressure test. In some applications, protective clothingneed only isolate the wearer from splashes

7、of liquids. This test method evaluates the integrity of theconstruction and configuration of liquid-penetration-resistant protective clothing or protectiveensembles with a shower spray test.Resistance of materials used in protective clothing to chemical permeation should be evaluated byTest Method F

8、739 for continuous contact and Test Method F1383 for intermittent contact (that is,splash), or by Test Method F1407 using the permeation cup method. Resistance of protective clothingmaterials to liquid penetration should be determined by Test Method F903. Resistance of protectiveclothing materials s

9、pecifically to blood and other potentially infectious materials should be determinedby Test Method F1670 and Test Method F1671.1. Scope1.1 This test method measures the ability of protectiveclothing or protective ensembles to resist liquid penetration inthe form of a shower spray with surfactant-tre

10、ated water.1.2 This test method measures the liquid penetration resis-tance of the construction and configuration of the overallprotective clothing or protective ensemble, but especially ofseams, closures, and interfaces with other components such asgloves, boots, hoods, and respiratory protective e

11、quipment. It isintended that this test method be used to assess the liquidpenetration resistance of protective clothing and protectiveensembles as received from the manufacturer and worn inaccordance with their instructions.1.3 Resistance of materials used in protective clothing topermeation or pene

12、tration can be determined in accordancewith Test Method F739 (or Test Method F1383 or Test MethodF1407) and Test Method F903, respectively. Alternatively,resistance of materials used in protective clothing to penetra-tion by synthetic blood or liquids containing virus can bedetermined in accordance

13、with Test Method F1670 and TestMethod F1671.1.4 The integrity of vapor protective ensembles is measuredby its ability to maintain positive internal pressure with TestMethod F1052.1This test method is under the jurisdiction ofASTM Committee F23 on PersonalProtective Clothing and Equipment and is the

32、ientations.4.3 Liquid penetration resistance is determined by the ab-sence of observable wetting of the inner liquid-absorptivegarment, or by the absence of observable liquid detected on theinterior of the specimen, or both.4.4 The test specimen is rated as passing if liquid does notpenetrate and as

33、 failing if liquid does penetrate.5. Significance and Use5.1 This test method evaluates the ability of the constructionand configuration of protective clothing or protective en-sembles to resist liquid penetration. In most cases, the condi-tions used in this test method will not represent actual end

34、-useconditions.5.2 Two different spray configurations are used for exposingthe protective clothing or protective ensemble on a manikin.5.2.1 Procedure A involves five shower nozzles with onenozzle directly above the clothed manikin and two nozzleseach to upper and lower sides of the manikin that are

35、 allpositioned in the same vertical plane. This spray configurationis intended to provide a full exposure of the entire protectiveclothing or protective ensemble system.5.2.2 Procedure B involves three shower nozzles that arepositioned at different heights on a vertical line that is parallelto the m

36、anikin with the locations and direction of each nozzleset with respect to targets on the manikin. This spray configu-ration is intended to provide a direct assessment of garmentfeatures such as the front closure.5.3 The selected duration of the test is not intended tosimulate user exposure to splash

37、es of liquid substances butrather to provide sufficient time for enough liquid to penetrateto make visual detection easier. The default liquid exposuretime for Procedure A is 20 min. The default liquid exposuretime for Procedure B is 10 min.5.3.1 It is permissible to specify shorter test durations.

38、It isrecommended that the duration of exposure be the same in eachmanikin orientation.5.3.2 The choice of different test duration is partly based onthe number of layers in the specimen being tested, some ofwhich serve to absorb the surfactant-treated test liquid andresult in attenuating the severity

39、 of the liquid challenge to thespecimen.5.4 A nontoxic, non-foaming surfactant is added to waterfor this test method to simulate liquids of lower surfacetensions. Liquids of specific interest can be simulated bytreating water to achieve an equivalent surface tension.5.5 For protective clothing with

40、water-repellent surfaces,the lower surface tension liquid will aid in the evaluation of theconstruction and configuration of the garment because it is lesslikely to be repelled and more likely to wet the protectiveclothing. This is especially useful for reusable garments whosewater-repellent surface

41、 interferes with the evaluation of theirconstruction and configuration when new, but is diminishedafter wearing and washing.5.6 Fluorescent or colored dyes are permitted to be added tothe water to enhance detection of liquid penetration into theprotective clothing or protective ensemble.5.7 This tes

42、t method can be used by both manufacturers andend users to assess liquid penetration resistance. Manufacturerscan use this test method to evaluate quality of construction andeffectiveness of clothing and ensemble configurations.5.8 The clothing or ensemble is sized to fit the manikin. It isimportant

43、 that the clothing be selected to fit the manikin wellsince detection of liquid penetration requires as much contactas possible between the clothing or ensemble and the innerliquid-absorptive garment.5.9 Results on a mismatched size of clothing or ensembleshall not be used to generalize about a part

44、icular constructionor configuration. Manikin fit potentially affects liquid penetra-tion resistance determinations.5.10 There are no known restrictions to the types of protec-tive clothing or protective ensembles that can be evaluated withthis test method.5.11 In some cases protective clothing or pr

45、otective en-sembles that show no liquid penetration during this test methodwill still fail to protect wearers against specific liquids due tothe material degradation, penetration, or permeation or theeffects associated with the vapors of liquid chemicals.5.12 In some cases protective clothing or pro

46、tective en-sembles that show no liquid penetration during this test methodwill fail to protect wearers in specific circumstances as, forexample, deluge or immersion.6.
