16、THOUT PERMISSION FROM UL INTRODUCTION 1 Scope 1.1 These requirements cover adhesive-attached labels for use as permanent nameplates or markers; bearing information, instructions, or identication in the form of text or pictographs. The adhesive may be pressure-sensitive, heat-activated, or solvent-ac

17、tivated. These labels are intended to be used by manufacturers for application to their products at their place of manufacture. 1.2 These requirements also cover: a) Unprinted materials used by label converters to produce nished labels, such as blank label stocks, overlaminations, laminating adhesiv

18、es and screen-printable adhesives; b) Specic combinations of label material, ink, and printing process evaluated as a system; and c) Labels that are intended to be mechanically affixed or molded into a plastic part. 1.3 These requirements apply to marking and labeling systems used on complete device

19、s, appliances, or equipment. The acceptability of a label system/material in a particular application is to be judged under the applicable requirements in the standard covering the device, appliance, or equipment on which the label system/material is used. 1.4 Marking and labeling systems are evalua

20、ted for specic uses and for application to specic surface materials that are essentially smooth, at, and rigid unless another surface conguration is specied by the manufacturer. 2 General 2.1 Values stated without parentheses are the requirement. Values in parentheses are explanatory or approximate

21、information. 3 Glossary 3.1 For the purpose of this standard, the following denitions apply. 3.2 FACE STOCK A polymeric lm, metal, paper, fabric, or laminated material capable of receiving printing. 3.3 FLOOD COAT A layer of ink that coats an area of the face stock, generally intended to provide bac

24、g process, and adhesive, where present. A system may also include an overlamination or an overprint coating. 3.9 MECHANICALLY AFFIXED LABEL A label intended to be affixed to a device using screws, rivets or other mechanical means of attachment. The means of attachment is not addressed by this standa

25、rd. Therefore the acceptability of the means of attachment must be determined for each device application. 3.10 OVERLAMINATION A transparent lm applied over printed face stock for protection. 3.11 OVERPRINT COATING A transparent coating, such as a varnish, applied over printed face stock for protect

26、ion. 3.12 PRINTING PROCESS A means by which ink is applied to face stock. 3.13 RELEASE LINER A removable component of a label or label stock that protects the adhesive prior to application. (Also known as backing.) 3.14 SUBSURFACE PRINTING Printing on the underside of the face stock. 3.15 TEMPERATUR

27、E RATING, MAXIMUM The highest surface temperature at which a label or label material is intended to be used. 3.16 TEMPERATURE RATING, MINIMUM The lowest surface temperature at which a label or label material is intended to be used. 3.17 TOP COATING A coating applied to face stock to improve ink rece

28、ptivity. 3.18 TOP-SURFACE PRINTING Printing on the topside of the face stock. PERFORMANCE 4 General 4.1 Labels or unprinted materials, applied or bonded to representative test surfaces and exposed to the applicable conditions as described in 4.1 7.3.4, shall show permanence and legibility as given i

29、n Table 4.1.

30、R REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL Table 4.1 Permanence and legibility Test Requirement Visual Examination The labels shall be viewed at arms length approximately 18 in (457 mm) by a person with normal or corrected vision. A label or unprinted material shall adhere to the test

31、 surface without any signicant curling or loosening around the perimeter greater than 10 percent of the label area, or other indication of loss of adhesion such as wrinkles or bubbles. It shall not excessively craze, shrink more than 10 percent of the label area or slip from its original position on

32、 the test panel more than 0.2 in (5.1 mm). Overlamination, if present, shall show no separation, excessive darkening or shrinkage of more than 10 percent of the label area. Printing, if present, shall be legible and there shall be no signicant deterioration of legibility such as fading or bleeding.

33、Signicant change in print colors shall be noted. Legibility Test Printed surfaces of labels are to be rubbed with thumb or nger back and forth ten times with a downward force of approximately 4 lb (18 N) and then examined for legibility as in the Visual Examination. a Printing shall be legible and t

34、here shall be no signicant deterioration or blurring of legibility. The top coating of unprinted label stock, if present, shall not be rubbed off. Defacement Test Labels or unprinted materials are to be scraped back and forth ten times across printed areas and edges, with a downward force of between

35、 1.6 and 2.0 lb (between 7.2 and 9 N) using the edge of a 0.065- to 0.100-in (1.65- to 2.54-mm) thick steel blade held at a right angle to the test surface. The portion of the blade contacting the test surface shall have a radius of curvature of 1.0 to 1.3 in (25.4 to 33.0 mm) and the edges of the b

36、lade shall be rounded to a radius of 0.016 0.003 in (0.41 0.08 mm). b A label or unprinted material, including overlamination or overprint coating, if present, shall remain in place and shall not be torn, uplifted, or otherwise damaged. Scratching or defacement of unprotected printing, either text o

37、r background, is not considered a non- compliance. Adhesion Test (8.2) This test is to be conducted if it is possible to remove test strips from surfaces. If removal as described in 8.2 is not possible because of breaking, tearing, or excessive rigidity of the label material, adhesion is to be deter

38、mined by attempting to remove the entire sample by hand. c The average quantitative adhesion value shall not be less than 0.50 lb/inch (0.088 N/mm) width and the adhesion shall not be less than 0.10 lb/in (0.0175 N/mm) at any point. If it is not possible to separate test strips from the surface, the

39、 sample shall show good adhesion to the surface when removal by hand is attempted. a Subsurface printed labels and labels in which printing is protected by an overlamination are not subject to the Legibility Test. b Labels intended to be mechanically affixed shall be evaluated by holding the label o

40、n a at test surface for support. c The adhesion test is not applicable to labels intended to be mechanically affixed. 4.2 If after any exposure condition the test surface excessively warps, bubbles, deteriorates, melts, chips, or otherwise renders it impossible to determine compliance of the label o

41、r label material with the requirements of this standard, the evaluation of the sample applied to the test surface is considered to be inconclusive.

42、ROM UL 4.3 Samples are to be representative of the construction of the marking and labeling system or unprinted material to be tested. Signicant construction variables such as top-surface or subsurface printing; top coating; face stock; overlamination or adhesive thickness range; partial adhesive co

43、verage; differing types or colors of similar face stock or adhesive (for example, clear, pigmented, or metallized); and alternative printing processes and inks (including oodcoating for subsurface printed constructions) are to be represented in the samples provided. 4.4 The minimum recommended sampl

44、e size is 2.0 by 2.0 in (50.8 by 50.8 mm) and the maximum recommended height of text is 0.063 in (1.60 mm). 5 Test Surfaces 5.1 Test surface panels are to be provided for each material on which the samples are to be tested. Panels are to be essentially at, smooth, and rigid, and are to measure appro

45、ximately 3 by 11 in (76.2 by 279.4 mm). Larger panels that can be cut, or smaller panels, if sufficient in number, may be used. If samples are to be investigated for use on a curved surface, curved surfaces or tubing of representative radius are to be provided. When samples are to be investigated fo

46、r use on a textured surface, panels of the specic textured surface are to be provided. 5.2 Test surfaces are to be cleaned as described in 5.3 5.5 before the samples are applied. 5.3 A test panel, except for wood, is to be repeatedly wiped with cheesecloth (bleached cotton gauze) dampened with denat

47、ured ethyl alcohol or isopropanol until it appears clean. The surface is then to be wiped once more, with the dampened cheesecloth turned to expose a clean area, and is then allowed to dry in air for at least 1 minute. 5.4 If alcohol affects the surface or is not considered the solvent of choice for

48、 a particular test surface: a) An alternative solvent that does not affect the surface or leave a lm is to be used; or b) A detergent and water solution is to be used, after which the surface is to be thoroughly rinsed with demineralized water, wiped with clean dry cheesecloth, and allowed to dry in

49、 air for 1 hour. 5.5 Bare wood surfaces, except for textured wood surfaces, may be lightly sanded with a 400 grit silicon carbide paper and then vacuumed to remove loose residual dust.
