Classification and Test Requirements4.1 All prot

20、ective clothing complying with this specificationshall fulfill the requirements of ISO 13688 and shall be testedand classified by the level of protection based on the material,seam, and garment requirements included in Sections 5-7.Information on tests to be conducted for each level of protec-tion i

21、s included in Table 1.4.2 Level 1 garments shall be made of materials and withseams that demonstrate a minimum liquid penetration resis-tance when tested in accordance with tests specified in Table 1.The mechanical strength performance requirements are thesame for all levels of garments, and the gar

22、ments shall pass apractical performance test.4.3 Level 2 garments shall be made of materials and withseams that demonstrate a higher level of liquid penetrationresistance than Level 1 garments. The mechanical strengthperformance requirements are the same for all levels. Thegarments shall pass a prac

23、tical performance test before beingsubmitted to a low-level spray test of the whole garment.4.4 Level 3 garments shall be made of materials and withseams that demonstrate a minimum level of resistance topenetration by liquids under pressure. It is possible thatadditional tests, such as permeation re

24、sistance testing with theactual test chemical, will be necessary to characterize fully thematerial for a particular application. When additional tests todetermine permeation are required, the penetration by liquidunder pressure shall be replaced by the permeation test. Whentested with specific pesti

25、cide formulations, information regard-ing the test chemical shall be included in the informationprovided with the garment. The mechanical strength perfor-mance requirements are the same for all levels. The garmentsshall pass a practical performance test before being submittedto a high-level spray te

26、st of the whole garment, which is moresevere than the test for Level 2 garments. Level 3 protectiveclothing includes accessories such as aprons, protectivesleeves, and material placed below knapsack/backpack spray-ers, which is used for extra protection during spraying, mixing,and loading. Whole bod

27、y testing is not required for accessoriesworn over whole body garments.5. Performance Requirements of Protective ClothingMaterials5.1 PreconditioningAll protective clothing materials ormaterial assemblies shall undergo 30 cycles of cleaning inaccordance with the manufacturers instructions before tes

28、ting,if the manufacturers instructions indicate that the garment canbe cleaned. However, garments that, in accordance with themanufacturers instructions, can be cleaned fewer than 30times shall undergo only as many cycles of cleaning asindicated by the manufacturers instructions. After the lastclean

29、ing cycle, materials to be tested for penetration shall beair dried and shall not be ironed before testing.NOTE 1Garments do not need to be dried between wash cycles.5.1.1 f the manufacturer requires special cleaning or main-tenance conditions, this information shall be included as part ofa warning

30、label in accordance with Section 8.NOTE 2The purpose of the warning label is to inform the user ofspecial requirements that, if not followed, have the potential to impact theprotective properties of the garment. Examples of special conditionsinclude, but are not limited to, use of a specific deterge

When additional tests to determine permeation a

35、re required, the penetration by liquid under pressure shall be replaced by the permeation test.F26690925.2 Material Penetration Resistance:5.2.1 Penetration testing for Level 1 and Level 2 garmentsshall be conducted in accordance with Test Method F 2130,Method A, using 0.2 mL of test chemical. The a

36、verage of threepercent penetration values shall be used to classify the mate-rial. If the average of three readings is within 10 % of thethreshold, the test shall be repeated for an additional set ofthree readings, and the average of six readings shall be used toclassify the material. If more than o

37、ne type of material is usedto construct the garment, three specimens of each material shallbe tested. Prowl 3.3, an emulsifiable concentrate with 37.4 %pendimethalin, diluted with distilled water to 5 % activeingredient (a.i.) shall be used. It is acceptable to substitute thetest chemical as long as

38、 it has been verified that the sameperformance rating for materials and seams is achieved.5.2.2 If the garment consists of a combination of separatelayers of materials, the outer layer shall be tested. Forsingle-layer garments constructed from different types ofmaterials, each material shall be test

39、ed separately and thepenetration classification based on the lowest performing level.5.2.3 Materials classified as Level 1 shall have an averagepenetration value #40 %. If the material fails to meet therequirement, Test Method F 2130, Method B, an analyticmethod, can be used to verify the results ob

40、tained for MethodA.5.2.4 Materials classified as Level 2 shall have an averagepenetration value of 5 % or less. If the material fails to meet therequirement, Test Method F 2130, Method B, an analyticmethod, can be used to verify the results obtained for MethodA.NOTE 3It is possible that some materia

41、ls, such as those with amicroporous membrane, will allow water and not the a.i. to penetratethrough the fabric. If bright yellow, the color of pendimethalin, is notvisible on the collector layer, proceed with analytical testing using MethodB.NOTE 4The pipette test is an accelerated laboratory test t

42、hat differ-entiates the penetration performance of materials. The maximum allow-able penetration of 40 % is derived from the pipette data analysis of cottonand cotton/polyester garment materials typically used for operator expo-sure studies. Therefore, it is not possible to substitute laboratory dat

43、a fromthe pipette method for field penetration data. For this reason, the 40 %limit shall not be used to calculate default protection factors used forexposure mitigation in operator exposure and risk assessment.5.2.5 The results shall be reported in the manufacturersproduct technical information (se

44、e Section 8).5.3 Material Resistance to Penetration by Liquid underPressure:5.3.1 Resistance to penetration by liquid under pressure forLevel 3 garments shall be tested in accordance with TestMethod F 903. Three specimens shall be tested for eachmaterial. Use Prowl 3.3, an emulsifiable concentrate w

45、ith37.4 % pendimethalin, diluted with distilled water to 5 % a.iTest the specimens at 0-kPa pressure for 1 min. Then increasethe pressure at increments of 1 kPa every minute until failureis observed or a maximum of 15 kPa is reached. A materialmeets the requirements if all three specimens pass the t

46、est at apressure 14 kPa. It is acceptable to substitute the test chemicalas long as it has been verified that the same performance ratingfor materials and seams is achieved.5.3.2 If the garment consists of a combination of separatelayers of materials, the outer layer shall be tested. Forsingle-layer

47、 garments constructed from different types ofmaterials, each material shall be tested separately and thepenetration classification based on the lowest performing level.5.3.3 The results shall be reported in the manufacturersproduct technical information (see Section 8).5.4 Material Resistance to Per

48、meation (Alternative to Liq-uid Pressure Test):5.4.1 When additional testing is required to characterizefully the material for a particular application, the material shallbe tested in accordance with Test Method F 739, and the lowestof three readings shall be used to determine the normalizedbreakthr

49、ough time (see Note 5). The test chemical shall be thespecific pesticide formulation diluted with water at the fieldstrength. Materials classified for Level 3 garments shall have anormalized breakthrough time 30 min for the active ingredi-ent (see Note 6).NOTE 5Normalized breakthrough time will be reached when thenormalized permeation rate of 1 g/cm2.min is achieved for an opencollecting medium (break time (BT) 1.0) or the normalized permeatingmass of 2.5 g/cm2.min is achieved for a closed collecting medium (BT2.5).NOTE 6Pesticide formulations are mixtu
