Classification and Test Requirements4.1 All protective clothing complying with this specificationshall fulfill the requirements of ISO 13688 and shall be testedand classified by the level of protection based on
21、the material,seam, and garment requirements included in Sections 5-7.Information on tests to be conducted for each level of protec-tion is 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 accord
22、ance with tests specified in Table 1.The mechanical strength performance requirements are thesame for all levels of garments, and the garments shall pass apractical performance test.4.3 Level 2 garments shall be made of materials and withseams that demonstrate a higher level of liquid penetrationres
23、istance than Level 1 garments. The mechanical strengthperformance requirements are the same for all levels. Thegarments shall pass a practical performance test before beingsubmitted to a low-level spray test of the whole garment.4.4 If, for a particular pesticide, additional testing is re-quired to
24、fully characterize the material (this shall be decidedon the basis of the risk assessment provided for the registrationof the specific pesticide), the material shall also be tested forpermeation resistance using the pesticide in question. Whentested with specific pesticide formulations, information
25、regard-ing the test liquid shall be included in the information providedwith the garment. The mechanical strength performance re-quirements are the same for all levels. The garments shall passa practical performance test before being submitted to ahigh-level spray test of the whole garment, which is
26、 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.

Performance Requirements of Protective ClothingMaterials5.1 PreconditioningAll protective clothing materials ormaterial assemblies shall undergo 30 cycles of cleaning inaccordance with the manufacturers instructions before testing,if the manufacturers instruc
28、tions 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 lastcleaning cycle, materials to be tested
29、 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 If the manufacturer requires special cleaning or main-tenance conditions, this information shall be included as part ofa warning label in accordance with Section
30、 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 detergent or use of heatsuch as tumble
31、dry or ironing to reactivate the repellent finish.TABLE 1 Testing Requirements for Level 1, 2, and 3 GarmentsSpecific Performance TestLevel1A23Material Requirements Liquid penetration resistance (Test Method F2130)xBxBResistance to penetration by liquid under pressure (Test Method F903)xResistance t

When tested with specific pesticideformulations, information regarding the test liquid shall be included in the information provided with the garment.F2669 1225.2 Material Penetration Resistance:5.2.1 Penetration testing for Level 1 and Level 2 garmentsshall be conduc
36、ted in accordance with Test Method F2130,Method A, using 0.2 mL of test chemical. The average 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
37、, and the average of six readings shall be used toclassify the material. If more than one type of material is usedto construct the garment, three specimens of each material shallbe tested.

38、edient (a.i.) shall be used. It is acceptable to substitute thetest chemical as long as 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, all layers shall be tested together with the
39、outer fabric exposed to the test chemical. For single-layergarments constructed from different types of materials, eachmaterial shall be tested separately and the penetration classifi-cation based on the lowest performing level.5.2.3 Materials classified as Level 1 shall have an averagepenetration v

If the material fails to meet therequirement, Test Method F2130, Method B, an analyticmethod, can be used to verify the results obtained 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,
41、Test Method F2130, Method B, an analyticmethod, can be used to verify the results obtained for MethodA.NOTE 3It is possible that some materials, 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, i
42、s notvisible on the collector layer, proceed with analytical testing using MethodB.NOTE 4The pipette test is an accelerated laboratory test that differ-entiates the penetration performance of materials. The maximum allow-able penetration of 40 % is derived from the pipette data analysis of cottonand
43、 cotton/polyester garment materials typically used for operator expo-sure studies. Therefore, it is not possible to substitute laboratory data fromthe pipette method for field penetration data. For this reason, the 40 %limit shall not be used to calculate default protection factors used forexposure

Use Prowl 3.3, an emulsifiable concentrate with37.4 % 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
46、 every minute until failureis observed or a maximum of 15 kPa is reached. A materialmeets the requirements if all three specimens pass the test 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
