The deleterious effects of these chemicals can rangefrom acute trauma such as skin irritation and burn, to chronic degenerative disease such as cancer.Since engineering controls cannot eliminate all po

    5、s. Protective clothing offering thehighest level of chemical protection is constructed 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 som

    6、e applications, chemical protectiveclothing need only isolate the wearer from splashes of liquids. This test method evaluates the integrityof the construction and configuration of liquid-penetration-resistant protective clothing or protectiveensembles with a shower-spray test.Resistance of materials

    7、 used in protective clothing to chemical permeation should be evaluated byTest Method F739 for continuous contact and Test Method F1383 for intermittent contact (that is,splash), or by Test Method F1407 using the permeation cup method.

    31、 to protect the wearer from chemical liquids, vapors,and gases.4. Summary of Test Method4.1 A test specimen (protective clothing or protective ensemble) is placed on a mannequin that is already dressed in aliquid-absorptive garment covering portions of the mannequin form that are of interest.4.2 Wat

    32、er, treated to achieve a surface tension of 0.032 6 0.002 N/m (32 6 2 dynes/cm) is sprayed at the test specimen fromfive nozzles positioned in a specific configuration with respect to the specimen. The specimen is exposed to the liquid spray fora period of 15 min in each of four specimen orientation

    33、s.4.3 Liquid penetration resistance is determined by the absence of liquid inside the specimen, or on the inner liquid-absorptivegarment. garment, or both.4.4 The test specimen is rated as passing if liquid does not penetrate and as failing if liquid does penetrate.5. Significance and Use5.1 This te

    34、st method evaluates the ability of the construction and configuration of protective clothing or protective ensemblesto resist liquid penetration. In most cases, the conditions used in this test method will not represent actual end-use conditions.5.2 The one-hour duration of the test is not intended

    35、to simulate user exposure to splashes of liquid chemical but rather toprovide sufficient time for enough liquid to penetrate to make visual detection easier.5.2.1 It is permissible to specify shorter test durations. The duration of exposure in each mannequin orientation must be thesame.5.2.2 The cho

    36、ice of different test duration is partly based on the number of layers in the specimen being tested, some of whichserve to absorb the surfactant-treated test liquid and result in attenuating the severity of the liquid challenge to the specimen.5.3 A nontoxic, non-foaming surfactant is added to water

    37、 for this test method to simulate liquids of lower surface tensions.Liquids of specific interest can be simulated by treating water to achieve an equivalent surface tension.5.4 For protective clothing with water-repellent surfaces, the lower surface tension liquid will aid in the evaluation of theco

    38、nstruction and configuration of the garment because it is not repelled but wets the protective clothing. This is especially usefulfor reusable garments whose water-repellent surface interferes with the evaluation of their construction and configuration whennew, but is diminished after wearing and wa

    39、shing.5.5 Fluorescent or colored dyes may be added to the water to enhance detection of liquid penetration into the protective clothingor protective ensemble.5.6 This test method can be used by both manufacturers and end users to assess liquid penetration resistance. Manufacturerscan use this test m

    40、ethod to evaluate quality of construction and effectiveness of clothing and ensemble configurations.5.7 The clothing or ensemble shall be sized to fit the mannequin. It is important that the clothing fit the mannequin well sincedetection of liquid penetration requires as much contact as possible bet

    41、ween the clothing or ensemble and the innerliquid-absorptive garment.5.8 Results on a mismatched size of clothing or ensemble shall not be used to generalize about a particular construction orconfiguration. Mannequin fit potentially affects liquid penetration resistance determinations.5.9 There is n

    42、o known limit to the kind of protective clothing or protective ensembles that can be evaluated with this testmethod.5.10 In some cases protective clothing or protective ensembles that show no liquid penetration during this test method will stillfail to protect wearers against specific chemicals due

    43、to the material degradation, penetration, or permeation or the toxicityassociated with the vapor of liquid chemicals.5.11 In some cases protective clothing or protective ensembles that show no liquid penetration during this test method will stillfail to protect wearers in specific circumstances as,

    44、for example, deluge or immersion.6. Apparatus6.1 Human-Form Mannequin, an appropriately sized human-form mannequin shall be selected for testing the protectiveclothing or protective ensemble. The selected mannequin should provide as much contact with the protective clothing or protectiveensemble as

    45、possible. The mannequin shall have a water-resistant coating. The mannequin shall have straight arms and legs withthe arms at the mannequins sides.F1359/F1359M 1336.2 Liquid-Absorptive Inner GarmentAn inner garment shall cover all areas of the mannequin that are of interest as an aidto observe liqui

    46、d penetration. The inner garment shall be constructed of fabric that is finish free and that is easily watermarked.Select an inner garment that contacts the test garment as closely as possible. Users of this test method may also use moresophisticated equipment for detecting liquid penetration.6.3 Sh

    47、ower SystemThe shower system shall consist of five low-flow shower head nozzles, and a pressurized liquid supply.Thefive nozzles shall be oriented with respect to the mannequin as specified in Fig. 1. The nozzles shall conform to the specificationsgiven in Fig. 2.3 The pressurized liquid supply shal

    48、l be delivered at 3.0 6 0.2 L/min 48 6 3 gal/h through each nozzle.6.4 Stopwatch, or other appropriate timing device.7. Precautions7.1 Conduct the test method in an area designed to collect liquid runoff.7.2 Keep unprotected observers from being exposed to the test liquid.7.3 After testing, and befo

    49、re returning the specimen to service or storage, ensure the following:7.3.1 The specimen is dry,7.3.2 The specimen is clean, and7.3.3 All parts are positioned correctly and secured tightly.8. Specimen Preparation8.1 Protective clothing or protective ensemble components, shall be tested as received and in accordance with themanufacturers instructions. Duct tape or other nonuniform methods for closing or sealing, or both, interfaces shall not be used.8.2 Parts of the protective clothing or protective ensemble that are not to be tested shall be suitably blocked off t
