2、the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers the evaluation of specificperformance characteristics of any washable or dryclea
3、nablesoft window covering.1.2 This specification is not a specification for washable ordrycleanable soft window coverings but may be used bymutual agreement between the purchaser and the supplier toestablish material specifications.1.3 This standard does not purport to address all of thesafety conce
4、rns, if any, associated with its use.

8、wall or window openings that are either lined orunlined and primarily constructed of textile fabrics.3.1.1.1 DiscussionWashable soft window coverings in-clude those that can be refurbished by any procedure in whichthe cleaning solvent is water. Drycleanable soft windowcoverings include those that sh
9、ould be refurbished by anyprocedure in which the cleaning solvent is primarily nonaque-ous and used in drycleaning.3.2 For definitions of textile terms used in this specificationrefer to Terminology D123 and Terminology D3136.4. Significance and Use4.1 This specification may be used to evaluate pert
10、inentperformance characteristics of washable and drycleanable softwindow coverings, whether lined or unlined.4.1.1 Soft window covering characteristics to be evaluatedprior to repeated refurbishing include, but are not limited to,seam strength and appearance, uniformity of shade (part topart), and s
11、ize consistency (side to side and part to part).4.1.2 Soft window covering characteristics to be evaluatedafter repeated refurbishing include, but are not limited to,colorfastness, dimensional change, seam strength, appearance,and compatibility of components. Compatibility of dimen-sional change bet

17、e areas shall be set by mutual agreement between purchaserand supplier.5. Sampling, Selection, and Number of Specimens5.1 Division into LotsFor acceptance testing, divide theproduct into lots as agreed upon by the purchaser and thesupplier.5.2 Lot SampleAs a lot sample for acceptance testing, takeat
18、 random the number of shipping cartons directed in anapplicable material specification or other agreement betweenthe purchaser and the supplier. Consider shipping cartons ofcurtains or draperies to be the primary sampling units.NOTE 1A realistic specification or other agreement between thepurchaser
19、and the supplier requires taking into account the variabilitybetween shipping cartons, between items within a carton, and betweenspecimens within an item so as to provide a sampling plan which has ameaningful producers risk, consumers risk, acceptable quality level, andlimiting quality level.5.3 Lab
20、oratory SampleAs a laboratory sample for accep-tance testing, take two random items from each shipping cartonin the lot sample.5.4 Test SpecimensTake test specimens from each item inthe laboratory sample as directed in the individual test meth-ods. Perform each test on the product as it will reach t

Characteristics6.1 The areas to be evaluated and the criteria assigned tothose areas shall be set by mutual agreement between pur-chaser and supplier.7. Fabric Performance Characteristics7.1 The fabric in the item shall be evaluated as directed inSpecifi
22、cation D3691.8. Product Performance Characteristics Prior toRefurbishing8.1 Seam performance shall be evaluated as directed in TestMethod D1683 (for woven) or Test Method D3940 (for knit)and in AATCC Method 88B, as appropriate.8.2 Mark and record measurements as directed in Section 11of this specifi
23、cation to establish size consistency, side to sideand part to part, and as a basis for determining dimensionalchanges.8.3 Examine the soft window coverings for unacceptableshade difference from part to part, using a commerciallyavailable laboratory light source as agreed upon by purchaserand supplie
24、r.8.4 Examine soft window coverings for any other pertinentdefects.9. Refurbishing Conditions9.1 Laundering:9.1.1 Launder soft window coverings as directed inAATCCMethod 135 as in the permanently attached care label instruc-tions. Use laundering temperatures as directed in AATCCMethod 135.9.1.2 Any
25、domestically available detergent, as agreed uponby purchaser and supplier, may be used.9.1.3 When chlorine bleach is to be used, introduce one cupof any liquid chlorine household bleach containing 5.25 %sodium hypochlorite (5 % available chlorine) into the washerin the manner directed on the bleach
26、container. When testingwith non-chlorine bleach is indicated, introduce it into thewasher in the amount and manner directed on the bleachcontainer.9.1.4 Dry items following care label instructions or asdirected in AATCC Method 135.9.1.5 When ironing is to be done, follow the methodindicated on the c

Measuring Soft Window Coverings11.1 Expose the item to standard textile conditions for atleast 4 h.D4720 08 (2013)211.2 When necessary, mark the dimension to be measuredwith a suitable marking device.11.3 Unless otherwise set by mutual agreement betweenpurchaser and supplier, ma
33、ke original measurement marks atthe locations according to Fig. 1, as follows:11.3.1 Measure length of soft window coverings at eachside of each panel, and in the middle of the panel, includingruffles, flounces and trims. Measure each panel separately(AA,Fig. 1).11.3.2 Measure width of soft window c
34、overings at top,middle, and bottom (if it is a pinch pleated item, then measurethe heading only, including all ruffles, flounces and trims).Measure each panel separately (B B, Fig. 1).11.3.3 Mark the inner edge of ruffle or flounce whereattached to item with 25-cm (10-in.) or 91.4-cm (36-in.) gagema
35、rks (D D, Fig. 1). Permitting all fullness to remain, markthe outer edge of the ruffle or flounce with corresponding gagemarks (E, Fig. 1). Measure the full fabric width betweensecond set of gage marks (E E, Fig. 1).11.3.4 On one panel of fabric, excluding ruffles andflounces, on both face and back
36、of the product, mark off witha suitable marking device, three 25-cm (10-in.) gage marksparallel to the length of the fabric, and three 25-cm (10-in.)gage marks parallel to the width of the fabric to the nearest0.25 cm (0.1 in.). Each set of the gage marks must be at least5.0 cm (2 in.) from all edge
37、s of the panel and approximately 12cm (5 in.) apart. Bench marks of 50 cm (20 in.) are commonlyused to facilitate better precision of measuring, so use thismeasurement if the product is large enough.NOTE 3When actual length and width measurements are made, thetolerances shall be to the nearest 1 mm
38、(116 in.). When gage marks areused, the measurement tolerances should be supplied by the gagemanufacturer. See Test Methods D3773.REPORTING AND CONFORMANCE12.
