Referenced Documents)4. Summary of Guide4.1 This guide provides guidelines for use by
18、 suppliers ofthe flame, thermal, and arc resistant clothing (including thefabric and fibers used in its construction), processors, and endusers to effectively care for and maintain flame, thermal, andarc resistant clothing. The guidelines include:4.1.1 A listing of elements to consider when developi
19、ngwash procedures and formulas for processor(s).4.1.2 Recommendations for removing flame, thermal, andarc resistant clothing from service.4.1.3 Recommendations for the repair, modification and fitof flame, thermal and arc resistant clothing.5. Significance and Use5.1 This guide identifies the respon
20、sibilities of the fiber,fabric, and clothing manufacturers, as well as the processor, theprocessors chemical supplier and the end user.5.2 This guide describes the key components involved in aprogram for the care and maintenance of flame, thermal, andarc resistant clothing.5.3 The guidelines in this
21、 standard will provide a processorassistance to develop a processing system that maintains theflame, thermal, and arc resistant characteristics of the clothingduring its useful service life.5.3.1 The development of published formulas for eachfabric and level of soiling is difficult at any given poin
22、t in timedue to ongoing continuous improvement of flame, thermal andarc resistant clothing, including new fibers, fabrics, and laun-dering equipment and procedures.5.4 The guide also provides suggestions as to when flame,thermal, and arc resistant garments should be removed fromservice.6. Procedure6
23、.1 Garment manufacturers, in consultation with fiber andfabric suppliers, are responsible for providing information onthe performance characteristics and maintenance needs of theirgarments. The end-user is responsible for understanding thehazards present in the workplace and selecting appropriateeng
24、ineering controls and protective equipment and garments toaddress those hazards.6.2 The processor should sort flame, thermal, and arcresistant clothing by fiber, fabric, finish, and soil level inconsultation with the chemical supplier, and wash separatelyfrom all other clothing.6.3 The processor, in
25、 consultation with the chemical sup-plier, should develop loading plans and wash formulas toremove soils, while maintaining the flame and thermal protec-tive characteristics of the garments.6.3.1 Laundry wash formulas should be developed by theprocessor and wash chemical supplier in collaboration wi
26、th theclothing and fabric manufacturers based on the followingcriteria:(1) Washing Machine Type and VolumeMachine Loading FactorMechanical ActionExtractionCycle Times(2) Product Classifications and Material Construction(3) Soil types and soil level(4) Sorting(5) Wash Room ChemistryWater TemperatureW
27、ater HardnessDetergent Make-upAdditives(6) Finishing ProcessType Finishing-Drying, Pressing, TunnelingMoisture RetentionFinishing TemperatureFinishing Time(7) Special Instructions prohibiting laundering (for ex-ample, “Dry Clean Only” or “Do Not Wash”.6.3.2 Based on the preceding criteria, some or a
28、ll of thefollowing processes may be included in the wash formula:6.3.2.1 FlushA high-level bath for a short period of timeprior to the break. Flushes generally are used for conditioningtextiles before subsequent baths and for removing loose soils.6.3.2.2 Break (Break Suds)The first wash chemical bat
29、h.In light and medium-soil formulas, all of the surfactant/detergent and alkali to be used in the entire formula is generallyadded to the washer in the break bath.6.3.2.3 SudsA bath occurring between the break andensuing steps. Suds baths are carried out at low water levels,usually with hot or warm
30、water. If alkali or detergent isntadded on these additional suds baths, they are referred to ascarryover.6.3.2.4 Carryover (Carryover Suds)A cleaning step in alaundry formula in which no supplies are added, but suppliespreviously added are retained for use.6.3.2.5 RinseHigh water-level bath or baths
31、 following thecarryover and preceding the sour or finishing bath. Duringrinsing the final portions of loosened soils are removed alongwith the bulk of the washing compounds used in laundering.Rinses are used to cool down the wash load. Except forantichlors, chemicals are usually not added to rinse.6
32、.3.2.6 Sour BathNormally the final bath in the launder-ing process. The purpose for the sour (or acid) bath is toneutralize the alkalinity of the water in the textiles beforeremoving them from the machine for finishing.F14490826.4 Load SizeSince proper loading of the washer isessential to effective
33、processing of flame, thermal, and arcresistant clothing, appropriate consideration of load size shouldbe made by the processor in coordination with the machinemanufacturer and the processors chemical supplier.6.5 Removal from ServiceFor most practical purposes,garments may be temporarily or permanen
34、tly removed fromservice for reasons as determined by inspection based onsubjective evaluation and advice by the processor. Ultimately,determination of when flame, thermal and arc resistant clothingshould be removed from service is the responsibility of the enduser.6.5.1 The following items, identifi
35、able by visual examina-tion, diminish the effectiveness of the flame, thermal, and arcresistant clothing. Other issues may also have such effects.6.5.1.1 Worn OutThin spots, holes, excessive wear atedges6.5.1.2 Mechanical DamageEvidence of cuts, rips, tears,open seams, and nonfunctional closures6.5.
36、1.3 RepairsTears, holes, open seams, lost buttons orsnaps are types of repairs. Each processor determines if thenumber and/or size of the repairs are acceptable to a garmentbefore removing the garment from service.6.5.1.4 ModificationsAlteration(s) to a garment that dif-fers significantly from the o
37、riginal design6.5.1.5 FitThe flame, thermal, and arc resistant clothingno longer fits the wearer; a garment may be assigned to anotherwearer if it meets all appropriate usability requirements.6.5.1.6 Flammable SubstancesGarments soiled by sub-stances that represent a flammability risk, such as solve
38、nts,solids, oils and other petroleum products that cannot beproperly cleaned; the presence of a petroleum or chemical odorcan be evidence of a flammable substance.6.6 RepairsRepairs of flame, thermal and arc resistantclothing shall be made using fabrics and components that areequivalent to those use
39、d in the original manufacturing. Prop-erly repaired garments may be returned to service in a FRclothing program.6.7 ModificationsFlame, thermal and arc resistant cloth-ing shall be modified using fabrics and components that areequivalent to those used in manufacturing. Altered garmentsthat differ si
40、gnificantly from original design or function shouldnot be worn.6.8 FitThe fit of flame, thermal and arc resistant clothingsignificantly impacts its protective performance. Garmentsshould fit comfortably and loosely without compromising othersafety considerations. Garments that fit improperly should
41、notbe worn.6.9 Permanent Removal from ServiceGarments that haveunrepairable damage, are worn out, or are unusable for othersafety reasons, are not to be reused.APPENDIX(Nonmandatory Information)X1.X1.1 The individual(s) providing the laundering should beadequately informed of the proper cleaning pro
42、cesses neededto ensure the flame, thermal, and arc resistant characteristics ofprotective clothing are maintained. Normally such advice isprovided by the chemical supplier, however additionally thegarment manufacturer and fabric supplier may have usefulinformation to pass on. For example, if chlorin
43、e bleach is usedin laundering, some types of FR clothing can be compromised.X1.2 Some potentially flammable materials such as sol-vents, oil, and other petroleum products may not be removedby home laundering, industrial laundering, or dry cleaning.When this occurs, use multiple or a combination of p
44、rocesses,such as dry cleaning followed by laundering which may assistin removing the flammable substances.ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentionedin this standard.
