3、ortation of chemicals canbe exposed to numerous substances capable of causing harm upon contact with the human body. Thedeleterious effects of these chemicals can range from acute trauma, such as dermatitis or burns, tochronic degenerative disease, such as cancer or pulmonary fibrosis. Since enginee
4、ring controls maynot eliminate all possible exposures, attention is often given to reducing the potential for direct skincontact through the use of protective clothing that resists degradation, penetration, and permeation.Chemical-protective ensembles range from outfits of gloves, boots, and coveral
5、ls to totally-encapsulating ensembles employing self-contained or airline-supplied, breathing apparatus. Theensemble of chemical-protective clothing in combination with gloves, boots, a breathing apparatus,and other auxiliary protective equipment can provide maximum protection to wearers in situatio
6、nswhen no contact with hazardous chemicals is permitted. Chemical-protective ensembles are oftenselected on the basis of material chemical resistance, but equally important are the comfort, fit,functionality, and overall integrity of the ensemble allowing the wearer to safely carry out his or herass
7、igned tasks. Few standards, if any, apply to the design and manufacture of chemical-protectiveensembles. Additionally, protective clothing designs vary depending on different end use applicationsin industrial settings, hazardous waste site clean up, and emergency response.As a consequence, usersare
8、faced with a variety of commercial products and generally depend on manufacturer salesinformation to decide which protective clothing is appropriate for their own application. Otherprotective equipment such as gloves, boots, respiratory protective equipment, communicationssystems, and cooling device
9、s must also be selected and integrated with the chemical-protectiveclothing to provide an ensemble with adequate protection.This standard is intended to provide standardized methods for qualitatively evaluating the comfort,fit, function, and durability of chemical-protective ensembles and ensemble c
10、omponents. It may alsobe used by protective clothing manufacturers to assess current or proposed designs.1. Scope1.1 These practices are intended for evaluating chemical-protective ensembles and ensemble components to determinethe suitability of the ensemble or ensemble components in awork environme

Summary of
23、 Practices4.1 In Option A, the durability of the chemical-protectiveensembles and ensemble components are evaluated by subject-ing the protective ensemble to a manned exercise scenario. Thesuit is inspected prior to and after the series of exercises toassess any changes in the garments integrity.4.2
24、 In Option B, the function of the chemical-protectiveensemble and ensemble components are evaluated by observ-ing the ability of a test subject to perform routine work taskswhile wearing the protective ensemble. As in Procedure A, thesuit is inspected prior to and after the series of tasks to assess
25、changes in the garments integrity.4.3 For each option, the fit and comfort of the chemical-protective ensemble and ensemble components are assessed bymeasuring the test subjects body dimensions and mass, andthe dimensions and mass of the ensemble. These measurementscan be qualitatively used to evalu
26、ate fit and comfort by relatingtest subject and ensemble measurements to test subject re-sponses following each test.5. Significance and Use5.1 These practices establish standard procedures designedfor qualitatively evaluating the performance characteristics ofchemical-protective suit ensembles in t
27、erms of comfort, fit,function, and durability.5.2 These practices are suitable for both end users andmanufacturers to evaluate performance characteristics of en-sembles and ensemble components.5.2.1 End users may use these practices to qualitativelydetermine how well ensembles and ensemble component
28、s(gloves, boots, breathing apparatus, communications systems,and cooling devices) meet their particular application.5.2.2 Manufacturers of ensembles and ensemble compo-nents may use these practices to determine the qualitativeperformance characteristics in existing or proposed designs.5.3 Procedure
29、A permits a qualitative evaluation ofchemical-protective suit integrity (materials, seams, and com-ponents) by subjecting the protective ensemble to a mannedexercise routine. Option B permits a qualitative evaluation ofensemble and component function. Each procedure can be usedto assess ensemble com
30、fort and fit by relating test subjectresponses and by comparing the dimensions and weights ofboth the test subject and suit.NOTE 1The accumulation of suit and human subject dimension datamay eventually be used by manufacturers or end users in standards toimprove the sizing of chemical-protective sui
31、ts and the integration ofensemble components in protective ensembles.5.4 The use of these practices is for qualitative purposesonly. In general, results from use of these practices on one typeensemble may not be comparable to other test results on adifferent ensemble due to the subjective nature of
32、test results.5.5 These practices are not intended to assess heat stressresulting from wearing a chemical-protective ensemble, al-though thermal comfort of the suit ensemble may be subjec-tively evaluated.2For referenced ASTM standards, visit the ASTM website, www.astm.org, orcontact ASTM Customer Se

Users of thesepractices may wish to consider additional tests and procedurethat relate directly to their p
35、articular application. Each facilityperforming these practices should establish its own criteria forassessing acceptable ensemble performance.6.
