This document supersedes EN 923:2005+A1:2008. This European Standard shall
26、 be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by June 2016, and conflicting national standards shall be withdrawn at the latest by June 2016. In comparison to EN 923:2005+A1:2008, several new terms have been added ( 3 terms t
27、o Section 2.1, 3 terms to Section 2.2, 7 terms to section 2.3, 3 terms to Section 2.4, 1 term to Section 2.5, 1 term to Section 2.6, 1 term to Section 2.7) and some definitions have been updated or corrected. Attention is drawn to the possibility that some of the elements of this document may be the
28、 subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. According to the CEN/CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgiu
29、m, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerl
30、and, Turkey and the United Kingdom. BS EN 923:2015EN 923:2015 (E) 4 Introduction This European Standard comprises terms peculiar to, or in general use in, the adhesive and adhesive processing industry. The terms defined have been classified so that, as far as possible, related concepts (adhesives, f
31、unctional adhesive components, chemical base products, adherents, adhesives properties, bonding, and bond properties) are grouped together. All definitions are numbered and an alphabetical index which includes all terms is provided at the end of this European Standard. The numbering of the individua
32、l definitions is the same in all three versions (English, French and German) of this European Standard. Consequently this European Standard can be used as a dictionary, combined with one or both of the other versions as an aid for translation of terms into French or German, as a source of informatio
33、n about related concepts in the adhesive industry or to provide a term for a concept. In order to find: a) the definition of a term: look up the term in the alphabetical index at the end of this European Standard. The index will refer to the number in this European Standard. The definition, the term
34、 and any synonyms appear by the number; b) information about related terms: look up the term in the alphabetical index to find its number in this European Standard. When the term has been located in this European Standard, the related concepts can be found in the same subdivision; c) the translation
35、 of a term into the French or German language: look up the number of this term in this European Standard and locate the translation of the term and the definition under the same number in the standard of the foreign version. BS EN 923:2015EN 923:2015 (E) 5 1 Scope This European Standard defines term
36、s used in the adhesive industry and terms relating to adhesives in those industries that use adhesives. 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 Adhesives 2.1.1 adhesive non-metallic substance capable of joining materials by surface bo
37、nding (adhesion), and the bond possessing adequate internal strength (cohesion) Note 1 to entry: Many adhesives names refer to their main functional components or the physical nature of the adhesive. Table A.1 lists main binders, temperature and mode of setting of these adhesives and the number of p
38、arts that have to be mixed before use. Some other names refer to the method of application, or the mode of setting. Furthermore, adhesives are named according to points of less significance: field of application (e.g. footwear adhesive, construction adhesive, packaging adhesive), material to bond (e
39、.g. paper adhesive, wood adhesive, wall paper adhesive, rubber adhesive), place of application (e.g. in situ adhesive), speed of setting (e.g. instant adhesive), bond properties (e.g. structural adhesive), shape (e.g. powder adhesive, pearl glue, table glue for solid glue, adhesive film for shaped a
40、dhesive, or stick adhesive for stick shaped adhesives), or aspect (e.g. white glue). 2.1.2 water-borne adhesive aqueous adhesive adhesive in which the solvent, or the continuous phase is water 2.1.3 glue aqueous adhesive specifically designed for bonding of wood and other porous substrates Note 1 to
41、 entry: A glue can be based on a natural product like protein or synthetic resins (UF, PF or PVAC, see 2.3.51, 2.3.52 and 2.3.30 respectively) BS EN 923:2015EN 923:2015 (E) 6 2.1.4 paste adhesive adhesive of a non-stringy, highly viscous nature Note 1 to entry: Paste adhesives based on starch or cel
42、lulose ethers are usually applied for paper bonding (e.g. paper bags or wall paper). 2.1.5 dispersion adhesive adhesive consisting of a stable dispersion of a polymer in a liquid continuous phase, usually water Note 1 to entry: Dispersion adhesives containing an elastomer as polymer conventionally a
43、re often termed “latex”. 2.1.6 emulsion adhesive adhesive consisting of a stable emulsion of a liquid hydrophobic resin in water 2.1.7 solvent-borne adhesive solution adhesive solvent-based adhesive adhesive in which the binder is dissolved in a volatile organic solvent 2.1.8 solvent free adhesive a
44、dhesive that is substantially free from organic solvents (see 2.1.7) Note 1 to entry: “Substantially free” means that organic solvents have neither been added in the basic elements of an adhesive nor during its process of manufacture out of these basic elements. “Low solvent adhesives” contain at mo
45、st 5 % of solvents based on total weight of the adhesive. 2.1.9 plastisol adhesive paste or liquid adhesive material comprising a dispersion of a polymer resin in a plasticizer that when partially heated, gels as the plasticizer is incorporated into the swollen polymer to form a solid system Note 1
46、to entry: The plastisol will be converted into a solid plastic simply by heating to fully fuse. 2.1.10 toughened adhesive adhesive which by virtue of its physical structure discourages propagation of cracks Note 1 to entry: The toughening can be achieved, for example, by the creation of a discrete e
47、lastomeric phase within the adhesive matrix. 2.1.11 spray adhesive adhesive that is projected in small particles by means of a pressure medium BS EN 923:2015EN 923:2015 (E) 7 2.1.12 gap-filling adhesive adhesive designed for filling wider gaps between uneven surfaces Note 1 to entry: For high streng
