10、All rights reserved iiiForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in
11、a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commissi
12、on (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical c
13、ommittees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall n
14、ot be held responsible for identifying any or all such patent rights. ISO 18932 was prepared by Technical Committee ISO/TC 42, Photography. This second edition cancels and replaces the first edition (ISO 18932:2005), of which it constitutes a minor revision. The following changes have been made to t
15、he first edition: updating of normative references; removal of the former Annex A. BS ISO 18932:2009ISO 18932:2009(E) iv ISO 2009 All rights reservedIntroduction Adhesives can either be permanent (of more interest to consumers mounting photos in albums) or reversible (of more interest to museums and
16、 conservators). This International Standard focuses on permanent adhesives, rather than on reversible adhesives. This International Standard assures that adhesives used to mount images are both permanent and photo safe. BS ISO 18932:2009INTERNATIONAL STANDARD ISO 18932:2009(E) ISO 2009 All rights re

22、ystems commonly consist of two basic forms: supported and unsupported. They are usually applied to the back of the print. Both systems use release-coated liners to protect the adhesive prior to use. Liquid adhesives require a compatible dispenser or applicator to apply the adhesive to the back of th
23、e print or the front of the mounting board. Pastes are more viscous and are usually applied with a brush or roller. Solid adhesives are usually adhered to the back of prints by manual pressure. Thermally-activated dry mounting adhesives shall have uniform thickness, be flexible, be essentially non-t
24、acky at normal room temperature and consist of two basic forms: supported and unsupported. BS ISO 18932:2009ISO 18932:2009(E) 2 ISO 2009 All rights reserved3.1.2 Reactivity The adhesive shall not cause discoloration of the print, paper or mounting board. The adhesive shall meet the requirements of t
25、he bleed test in Clause 5 and the requirements of the photographic activity test in Clause 6. 3.1.3 Coating Pressure-sensitive adhesives shall be applied uniformly to each side of a supporting carrier or a release liner. The adhesive surface shall be tacky to the touch at 23 C. Thermally-activated a
26、dhesives shall be uniformly coated on both sides of a carrier membrane or be independent as a dry unsupported sheet. The thermally-activated film adhesive shall have uniform thickness and be flexible, dry and essentially non-tacky at 23 C. Thermally-activated film adhesives do not have release liner
27、s. 3.1.4 Physical characteristics Important physical properties of the supports and adhesive layers of thermally-activated and pressure-sensitive adhesive materials shall include: a) no surface structures that could impart texture patterns to the image due to pressure applied in mounting; b) uniform
28、 thickness and resistance to damage caused by handling; c) no voids, particles or other irregularities; d) uniformly white or light colours if transparent; uniform colour if translucent or opaque. 3.1.5 Liners Protective liners shall be easily removed from the adhesive without tearing or delaminatin
29、g. The release coating on the release liners shall be uniformly coated without voids or streaks and shall be sufficiently bonded to the liner to prevent any transfer to the adhesive. 3.2 Types of construction 3.2.1 Supported pressure-sensitive adhesives This adhesive system consists of a layer of pr
30、essure-sensitive adhesive coated on both sides of a carrier. The carrier may be any relatively thin, flexible material such as paper, film, polyester web, non-woven synthetic, etc. The carrier shall be uniform in thickness and appearance. The carrier shall comply with all requirements for paper or p
31、lastic materials in ISO 18902 and shall pass Photographic Activity Testing (PAT) in accordance with ISO 18916. This product is supplied in three basic forms: in roll form with one release liner; in roll or sheet form sandwiched between two release liners; coated on one side of a mounting board with
32、one release liner. Pressure-sensitive adhesives shall be free from imperfections and conform to ISO 18916 and ISO 18902. BS ISO 18932:2009ISO 18932:2009(E) ISO 2009 All rights reserved 33.2.2 Unsupported pressure-sensitive adhesives This adhesive material has a single uniform layer of adhesive that
33、is not reinforced or supported by a carrier. The product is supplied in three basic forms: in roll form with one release liner; in roll or sheet form sandwiched between two release liners; coated on one side of a mounting board with one release liner. 3.2.3 Supported thermally-activated adhesives Th
34、is adhesive system consists of a layer of a thermally-activated adhesive film coated on both sides of a carrier. The carrier may be any relatively thin, flexible material such as paper, film, polyester web, non-woven synthetic, etc. The carrier shall be uniform in thickness and appearance. The carri
35、er shall comply with all requirements for paper or plastic materials in ISO 18902 and should pass PAT in accordance with ISO 18916. The product is supplied in four basic forms: in roll form; in sheet form; coated on one side of a mounting board; coated on one side of canvas or other soft substrate w
36、ith or without one release liner. 3.2.4 Unsupported thermally-activated adhesives This adhesive system consists of a single uniform layer of adhesive that has not been reinforced or supported by a carrier. The product is supplied in four basic forms: in roll form; in sheet form; coated on one side o
37、f a mounting board; coated on one side of canvas or other soft substrate with or without one release liner. 3.3 Types of thermally-activated materials 3.3.1 Type I Non-removable The adhesive of this mounting material shall provide bonding between print and mounts, preventing deliberate separation to
38、 the print or mounting board surface by reheating for the time as specified by the manufacturer and temperature specified in 3.4.1 and 3.4.2. This type of adhesive will permanently bond after having reached recommended time/adhesion temperature within the mounting system. 3.3.2 Type II Removable The
39、 adhesive of this mounting material shall allow separation of the print from the mounting board without injury to either surface by reheating to the temperatures specified in 3.4.1 and 3.4.2, but otherwise shall maintain satisfactory bonding. Thermally-detachable adhesives shall be cooled under pres
40、sure for no less than 15 s to activate the bond. BS ISO 18932:2009ISO 18932:2009(E) 4 ISO 2009 All rights reserved3.4 Classes of thermally-activated materials 3.4.1 Class 1 Low temperature The thermally-activated coating shall provide adhesion at temperatures of 66 C to 108 C. 3.4.2 Class 2 High tem
41、perature The thermally-activated coating shall be adhesive at temperatures of 108 C to 163 C under the conditions of time and temperature specified by the manufacturer. This class of adhesives is not recommended for resin-coated (RC) or digital imaging materials because the required temperatures are
42、 likely to damage the emulsion surface and/or the colorants. 3.5 Other adhesives 3.5.1 Liquid Liquid adhesives are transparent, translucent, opaque or colour-changing. 3.5.2 Pastes Pastes are more viscous than liquid adhesives and are typically translucent or opaque. 3.5.3 Solid Solid adhesives incl
43、ude glue sticks and are typically translucent, opaque or colour-changing. 3.6 Adhesive strength 3.6.1 Pressure-sensitive adhesive strength The adhesive should form an immediate bond to the print as well as the mounting board when pressed together with enough uniform pressure to provide intimate cont
44、act. This is typically best accomplished using roll-laminating equipment so as to prevent any air entrapment during the bonding process. Adhesion should be such that forcible separation results in tearing, delaminating or distortion of the print or mounting board. If none of these occur, minimum bon
45、d strength of 1,3 N/cm (132 g-force/cm) shall be obtained when tested in accordance with 4.1 to 4.6. 3.6.2 Thermally-activated adhesive strength When available, the manufacturers recommended procedures shall be used for mounting the print. Adhesion shall be completed within 120 s after reaching bond
46、 temperature in all cases. Applied pressure shall be uniform and high enough to evenly bond. Adhesive strength and longevity is directly related to the correct amount of bonding time, proper temperature, adequate pressure and reduced moisture content. Adhesion should be such that forcible separation
47、 results in tearing, delaminating or distortion of the print/ mounting board. If none of these occur, minimum bond strength of 1,3 N/cm (132 g-force/cm) shall be obtained when tested in accordance with 4.1 to 4.6. The adhesive strength of Type I adhesives shall be sufficient to prevent peeling of th
48、e print from the mount during the cooling period. Type II adhesives bond during cooling; therefore, the adhesive strength shall be sufficient to prevent peeling of the print from the mount after cooling for 30 s or to 10 C below the bonding temperature.

If the thermally-activated adhesive of a mounting material tends to block under normal storage or use conditions, it shall be protected with an appropriate interleaving material, such as waxed or silicone-treated paper. However, slight-to-moderate blocking is acceptable at room temperature, even with interleav
