4.4 An eyewash/safety shower shouldbe located nearby and an organic vaporrespirator should be readily available foremergency use.
4.5 Exposure to chemicals used in thisprocedure must be controlled at or belowlevels set by governmental authorities(e.g.,Occupational Safety and HealthAdministration’s[OSHA]permissibleexposure limits [PEL] as found in 29CFR1910.1000; see web site:www.osha.gov for latest version). In ad-dition, the American Conference of Gov-ernmental Industrial Hygienists (ACGIH)Threshold Limit Values (TLVs) com-prised of time weighted averages (TLV-TWA)，short term exposure limits (TLV-STEL) and ceiling limits (TLV-C) arerecommended as a general guide for aircontaminant exposure which should bemet (see 10.2).
5. Apparatus and Materials (see 10.3)5.1 Accelerated laundering machinefor rotating closed canisters in a thermo-statically controlled water bath at 40 ±2rpm.
5.2 Stainless steel cylindrical contain-ers, 203× 89 mm (8.0×3.5 in.) in diame-ter equipped with solvent-resistant rings.5.3 Teflon liners.
5.4 Metal adapters (to hold containerson shaft of accelerated laundering ma-chine)(see 10.9).
5.5 Stainless steel balls,6.3 mm (0.25in.).
5.6 Gray Scale for Color Change(AATCC Evaluation Procedure 1) (see10.4).
5.7Perchloroethylene,drycleaning grade.
7.1 Run Number 1: Place the specimenin a steel container with 150 mL of per-chloroethylene,1 mL drycleaning deter-gent (see 10.6) and 100 steel balls.Sealthe container (see 10.7), clamp in the ac-celerated laundering machine and run atroom temperature 27C (81F) for 10min. Drain.
7.2 Run Number 2: Replace the solventwith an equal amount of perchloroethyl-ene without detergent and run another10 min. Drain.
7.3 Run Number 3: Repeat Run Num-ber 2. Remove the specimen,blot thor-oughly between paper towels and air dry.7.4 Finish the specimen by one of thefollowing methods:
7.4.1 Hand Pressing [for all except pilefabrics (see 10.8)]—Cover with a dampmuslin cloth,weighing 135-153 g/m2(4.0-4.5oz/yd2)，previously saturatedwith water and wrung out so as to retainmoisture equal to approximately 75% ofits dry weight and press with a hand ironhaving a temperature between 135-150°C(275-300°F)until dry.
7.4.2 Steam Pressing [for all exceptpile fabrics (see 10.8)]—A hotbed or pol-ished metal-top type press for flat fabrics,or a cloth-top type press for roughcrepes，operating at a steam pressure ofbetween 448 and 482 kPa (65-70 psi).Lower the head of the machine and holdin contact with the fabric. During this pe-riod admit steam from the buck of thepress for a period of 5-10 s.
8.1 Durability of Applied Designs—Rate the specimens containing flock,metallic or other applied designs for ap-pearance as follows:
Grade A5—negligible or no change inappearance.
Grade A4—slightly changed in appearance.
Grade A3—noticeably changed in appearance.
Grade A2—considerably changed inappearance.
Grade Al—much changed in appearance.
8.2 Durability of Fabric Handle—Ratespecimens for change in handle as follows:Grade B5—negligible or no change inhandle.
Grade B4—slightly changed in handle.Grade B3—noticeably changed in han-dle.
Grade B2—considerably changed inhandle.
Grade B1—much changed in handle.8.3 Finish Performance—Evaluate fin-ish performance characteristics in accor-dance with TM22.
9.1 Precision. Precision for this testmethod has not been established. Until aprecision statement is generated for thistest method, use standard statistical techniques in making any comparisons of testresults for either within-laboratory orbetween-laboratory averages.
9.2 Bias.The durability of applied de-signs and finishes to drycleaning can bedefined only in terms of a test method.There is no independent method for determining the true value. As a means ofestimating this property, the method hasno known bias.
10.Notes
10.1 This test is based on an extensive series of interlaboratory tests which showedgood correlation between laboratory tests andcommercial drycleanings for as many as threerepeated drycleanings.Since a major loss offinish material occurs in the first drycleaning,a single application of this test furnishes agoodindication of the effect of repeateddrycleanings.

10.5 Use any reputable supplier of dry-cleaning detergent.
10.6 Where residual soap affects the perfor-mance of the finish (e.g.,where water-repel-lency evaluation is impaired by the presenceof detergent) the detergent may be omittedfrom the test solution,but it is an artificialcondition.
10.7 The jars need not be immersed in awater bath as required in washfastness tests.10.8 Pile fabrics need only be air dried byany suitable means.
