17、 of soil levels commonly used in the laundry indus-try; the definition of each category depends on the soils, fabrictype, garment construction, and fabric release properties.(Refer to “The Textile Laundering Technology Handbook” inSection 2. Referenced Documents)4. Summary of Guide4.1 This guide pro
18、vides guidelines for use by 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 element
19、s to consider when developingwash 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
20、guide identifies the responsibilities 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
21、.5.3 The guidelines in this 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
22、difficult at any given point 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 remove
23、d fromservice.6. Procedure6.1 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 a
24、nd selecting appropriateengineering 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 clo
25、thing.6.3 The processor, in consultation with the chemicalsupplier, 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 sup
26、plier in collaboration with 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 Ch

28、ing criteria, some or all 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
29、first wash chemical bath.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,us
30、ually with hot or warm 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 wa
31、ter-level bath or baths 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 usual
32、ly not added to rinse.6.3.2.6 Sour BathNormally the final bath in the launder-ing process. The purpose for the sour (or acid) bath is toF1449 08 (2015)2neutralize the alkalinity of the water in the textiles beforeremoving them from the machine for finishing.6.4 Load SizeSince proper loading of the w
33、asher isessential to effective 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
34、 may be temporarily or permanently 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.
35、1 The following items, identifiable by visualexamination, diminish the effectiveness of the flame, thermal,and arc resistant clothing. Other issues may also have sucheffects.6.5.1.1 Worn OutThin spots, holes, excessive wear atedges6.5.1.2 Mechanical DamageEvidence of cuts, rips, tears,open seams, an
36、d nonfunctional closures6.5.1.3 RepairsTears, holes, open seams, lost buttons orsnaps are types of repairs. Each processor determines if thenumber or size of the repairs, or both, are acceptable to agarment before removing the garment from service.6.5.1.4 ModificationsAlteration(s) to a garment that
37、 dif-fers significantly from the original design.6.5.1.5 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
38、 a flammability risk, such as solvents,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 compone
39、nts that areequivalent to those used 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 manufactur
40、ing. Altered garmentsthat differ significantly 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. G
41、arments that fit improperly should 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)X1.1 The individual(s) providing the laundering should beadequately inf
42、ormed of the proper cleaning processes 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
43、pass on. For example, if chlorine bleach is usedin laundering, some types of FR clothing can be compromised.X1.2 Some potentially flammable materials such assolvents, oil, and other petroleum products may not be re-moved by home laundering, industrial laundering, or drycleaning. When this occurs, us
44、e multiple or a combination ofprocesses, such as dry cleaning followed by laundering whichmay assist in 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.
