1、Designation: D 4800 94 (Reapproved 2005)Standard Guide forClassifying and Specifying Adhesives1This standard is issued under the fixed designation D 4800; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A
2、 number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This guide provides a classification system for tabulat-ing the properties of adhesives suitable for holding parts orassemblies toget
3、her. The use of this guide also providesinformation necessary for the development of standard speci-fications for adhesives.NOTE 1This classification system may serve many of the needs ofindustries using adhesives. This guide is subject to revision as the needrequires; therefore, the latest revision
4、 should always be used.1.2 LimitationsThis classification system is intended to bea means of identifying adhesives. It is not intended for theselection of materials. Material selection should be made bythose having expertise in the adhesives field after carefulconsideration of the design and the per
5、formance required of thepart, the environment to which it will be exposed, the attach-ment process to be employed, the inherent properties of thematerial not covered in this document, and the economicfactors.1.3 This classification system is based on the premise thatadhesives can be arranged into br
6、oad generic families usingbasic properties to arrange the materials into groups, classes,and grades.1.4 In all cases where the provisions of this classificationsystem would conflict with the referenced ASTM specificationfor a particular material, the latter shall take precedence.1.5 The values state
7、d in SI units, as detailed in IEEE/ASTMSI 10, are to be regarded as the standard.2.

Classification5.1 Fig. 1 summarizes the classification system as detailedin this guide.5.2 Adhesives shall be classified on the basis of their broadgeneric
16、 family. The generic family is identified by letterdesignations as found in Table 1.NOTE 2For example: CA = Cyanoacrylate.5.2.1 The generic family is based on the broad chemicalmakeup of the base materials. By its designation, certaininherent properties are specified.5.3 The generic family is classi
17、fied into groups according,in general, to the chemical composition. These groups arefurther subdivided into classes and grades, as shown in thebasic property table that applies. The letter designation appli-cable is followed by a four-digit number indicating group,class, and grade.5.3.1 The basic pr
18、operty tables have been developed toidentify the commercially available adhesives into groups,classes, and grades. These tables are found in the standardslisted in Table 1.5.3.1.1 Where a standard does not exist for this classifica-tion system the letter designation for the generic family will befol
19、lowed by four 0s and the use of the suffixes as needed (see7.1).NOTE 3Example: SI0000 indicates a Silicone (SI) from Table 1, with0000 indicating no basic property table.5.4 To facilitate the identification of new or special materi-als where basic property tables are not provided in a materialspecif
20、ication, cell tables will be used. These tables shall appearin the material specifications. (See example of cell table in Fig.2.)5.4.1 Although the values listed in the cell tables include therange of properties available in existing materials, users shouldnot infer that every possible combination o
21、f properties exists orcan be obtained.5.4.2 The requirements for special adhesives will use theclassification system, as described, by the addition of a singleletter that indicates the proper cell table in which the propertiesare listed. A specific value is designated by the cell number foreach prop
22、erty in the order in which they are listed in the table.When a property is not to be specified, a zero is entered as thecell number. Likewise, when an acceptable value is notavailable in the cell table, the number 9 should be used and asuffix used indicating the specific value (see 7.1). Thus, thele
23、tter designation “A” for cell table and 3400 for propertyvalues shall always be written A3400.NOTE 4An example of an anaerobic adhesive identified by thisclassification system is as follows. The designation AN0120A3400indicates the following with the material requirements from Cell Table Aof materia

Basic Requirements6.1 The cell tables included as part of
25、the listed referencestandard shall be used to develop a line call-out for thematerials listed in Table 1 covered by a material standard.6.2 When the existing cell table does not adequately de-scribe the material, then suffixes may be used in place of a celltable designation.6.3 A line call-out assem
26、bled using the standard becomes aspecification. The line call-out shall contain the broad andspecific type of adhesive together with the appropriate identi-fiers, followed by special suffix requirements, as they apply.12 345| SPECIFIC | CELL REQUIREMENTS | | Table | SuffixBroadGenericTypeGroupXXClas

31、94 (2005)27. Suffix Requirements7.1 When requirements are needed that supersede or supple-ment the property table or cell table requirements, they shall bespecified through the use of suffixes. In general, the first suffixletter indicates the special requirement needed and the secondletter indicates
32、 the condition or test method, or both, with athree-digit number indicating the specific requirement. Thesuffixes that may be used are listed in Table 2.7.2 Basic requirements from property or cell tables, as theyapply, are always in effect unless these requirements aresuperseded by special suffix r
33、equirements in the line call-out.NOTE 5When using the suffixes for additional requirements of thematerial, the user must keep in mind that not all tests are routinelyconducted by the supplier. When these requirements are necessary toidentify particular characteristics important to specific applicati
34、ons theyshall be agreed upon between user and supplier.7.3 When a standard for a material is listed in Table 1, therequirements of the referenced standard apply.
