Terminology3.1 For definitions of terms relating to UV protective Textiles refer to Terminology D123.3.2 The following terms are relevant to this standard
16、: UV protective textile, ultraviolet protection factor (UPF), and UVprotection categories.3.3 For definition of other terms related to textiles, refer to Terminology D123.4. Significance and Use4.1 This guidespecification to labeling provides a uniform system of labeling on UV-protective textiles th
17、at informs consumersabout the amount of UV-protection provided.4.2 UV-protective textiles labeled according to this standard will permit consumers to compare the amount of protectionprovided by various textiles and purchase the product that best meets their sun protection needs.4.3 UV-labeling is in
18、 addition to other required labeling of garments including Permanent Care Labels and fiber content(composition) labels.4.4 Manufacturers are encouraged to provide information to consumers that aids in selecting products that provide the amountof UV-protection desired.4.5 UV-protective textiles label
19、ed according to this standard guidespecification will be labeled with a UPF value. AATCC TestMethod 183 must be used to determine the mean UPF values of unprepared specimens, of specimens prepared using PracticeD6544 (prepared-for-testing specimens), and of specimens taken from garments labeled, “Wa
20、sh once before wearing,” thesespecimens being taken after the garment is laundered once according to label directions. The latter specimens are referred to aslaundered-once specimens in this document.Alabel UPF will be calculated for the various types of specimens following directionsprovided in thi
21、s document. Usually, the value to be placed on the product label will be the label UPF calculated for theprepared-for-testing specimens or the label UPF calculated for the unprepared specimens, whichever is the lower value. In the caseof products to be labeled, “Wash once before wearing,” or similar
22、 wording, the UPF value to be placed on the product label willbe either the UPF calculated for the prepared-for-testing specimens or the laundered-once specimens, whichever value is the lowerone.4.5.1 DiscussionThe UPF value to be placed on a garment label needs to be the lowest protection value exp
23、ected duringconsumer use over a two-year period. Usually, this UPF value will be that obtained for the prepared-for-testing specimens becausethey have been laundered 40 times and exposed to UV-radiation to simulate conditions expected to lower the UPF during consumeruse. However, for certain fabrics
24、, knits in particular, the fabric manufacturer must tenter (stretch) the fabric to standard width forthe garment manufacturer. This process decreases the UPF of the fabric dramatically because the optical porosity, which has asignificant influence on UPF, is increased and does not represent the lowe
25、st UPF provided to the consumer because after the firstlaundering shrinkage may restore the lost protection by reducing the optical porosity of the fabric. In these cases, the value tocompare to the prepared-for-testing value is logically that of laundered once specimens.4.6 UV-protective labeling i

Determina
27、tion of Mean UPF of Prepared-for-Testing Specimens5.1 The determination of Mean UPF (UPFm) of prepared-for-testing specimens is based on measurements on specimens thathave been exposed to environments that may alter the transmittance of ultraviolet radiation through them. Fabric specimens shallhave
28、been prepared for UV transmittance testing according to Practice D6544. All specimens shall be tested in the dry state. Formaterials that are intended to be used where there is a likelihood that the garment will be worn wet, specimens may also be testedin the wet state according to AATCC 183. If the
29、 end use product/garment is expected to be worn wet the purchaser and suppliershould agree upon whether a material should or should not be tested in the wet state.5.2 The measurement site UPF (MSUPF) is the arithmetic average of the UPFs obtained when a prepared-for-testing specimen,is rotated in sp
30、ectrophotometric equipment as directed inAATCC 183.The MSUPFshall be calculated for the dry specimen, MSUPFdry using Eq 1.

Using Eq 3 Calculate UPFmfor the dry specimen , UPFm-dry and as needed the wet specimen, UPFm-wet.UPFm5UPF11 UPF211 UPFNN(3)where:N = the number of prepared-for-testing test specimens.6. Determination of Mean UPF of
33、Unprepared and Laundered-once Specimens6.1 The Mean UPF (UPFm) must be calculated using the UPF specimen values of the unprepared specimens or the UPF valuesof the laundered-once specimens. Proper sampling procedures as stated in Practice D6544 should have been followed in selectingthe yardage from
34、which the unprepared specimens are taken and likewise proper sampling procedures should be followed inselecting the garments to be laundered and from which the laundered-once specimens are taken.6.2 The measurement site UPF (MSUPF) is the arithmetic average of the UPFs obtained when an unprepared sp
35、ecimen orlaundered-once specimen, is rotated in spectrophotometric equipment as directed in AATCC 183. The formula to use is that in 5.2except that N = the number of measurements at a site on the unprepared or laundered-once specimen.6.3 The test specimen UPF (TSUPF) is the arithmetic average of the
36、 measurement site UPFs. The formula to be used is that in5.3.6.4 The mean UPF (UPFm) is the arithmetic average of the test specimen UPFs. The formula for calculating it is in Eq 3 exceptthat N = the number of unprepared or laundered-once test specimens.7. Determination of the Standard Error in the M

Determination of UPF Value for Label8.1 The UPF value to
39、be placed on the label is the sample UPF minus the standard error (E) of the sample UPF, the result ofwhich has been rounded down to the nearest multiple of five in all cases except when the calculated UPF is less than the lowestspecimen UPF for the sampling unit. Eq 6 should be used to calculate a
40、UPF for the prepared-for-testing specimen data and foreither the unprepared or the laundered-once specimen data in the dry state and as needed the wet state as a first step in determiningthe UPFs to be compared:UPF value for label a multiple of five! 5 Sample UPF E (6)8.2 The lower of the two values
41、 determined in 8.1 shall be selected.8.2.1 DiscussionThe UPF value to be placed on a label is to be the lowest UPF value of the fabric. In most cases preparingthe specimens according to Practice D6544 will cause the UPF of the prepared-for-testing specimens to be less than that of theunprepared spec
42、imens or laundered-once specimens. However, in certain cases, the UPF of the prepared-for-testing specimens maybe greater than that of the unprepared specimens or the laundered-once specimens (perhaps due to fabric shrinkage). In this case,the UPF on the label must be the lower of the UPFs, that of
43、the unprepared specimens.8.3 The selected UPF must be compared to the specimen UPF values of that sample.8.3.1 When the UPF value calculated in 8.1 and selected in 8.2 is less than the lowest UPF for any specimen in the sample(prepared- for- testing sample, unprepared sample, laundered-once sample i
44、n the dry state and as needed the wet state), then thevalue of UPF to be placed on the product label is the UPF value of the sample which is then rounded down to the nearest multipleof five but not greater than 50.D6603 1238.3.2 When the UPF value calculated in 8.1 and selected in 8.2 is greater tha
45、n the lowest UPF for any specimen in the sample(prepared-for-testing sample, unprepared sample, laundered-once sample in the dry state and as needed the wet state), then thevalue of UPF to be placed on the product label is the UPF of that specimen with the lowest UPF value which is then rounded down
46、to the nearest multiple of five but not greater than 50.8.3.3 DiscussionWhen variability is low, the UPF value that appears on the label will be the same as the mean UPF but whenvariability is high, the UPF value that appears on the label will differ from the mean UPF value. Fabrics with an extremel
47、y highUPF may have a very high standard deviation that can result in a calculated UPF value for the label that is less than any of theindividual UPF measurements. The use of the lowest individual measurement of UPF is therefore more representative of theUV-protection the fabric provides than the cal
48、culation that includes the error.8.4 When the calculated value of UPF for the label is greater than 50, then the value to be placed on the label shall be givenas 50+.8.5 When the calculated value of UPF for the label is less than 15, the product may not be labeled as sun or UV-protective.9. Determin
49、ation of Protection Classification9.1 The UPF value calculated in Section 8 shall be used to determine the protection category for the UV-protective textile.9.1.1 For the Good UV-protection category to be stated on the label, the UPF value must lie between 15 and 24.9.1.2 For the Very Good UV-protection category to be stated on the label, the UPF value must be between 25 and 39.9.1.3 For the Excellent UV-protection category to be stated on the label, the UPF value must be 40 or greater.10.
