Asgm — 08b Standard Terminology of Adhesives1 This standard is issued under the? A number in parentheses indicates the year of last reapproval. Terms that are generally understood or adequately de? Also, the following codes are included after the year of publication to describe the type change that was made: The deleted terms do not appear in the text of the standard. Current edition approved Oct. Originally approved in Last previous edition approved in as D — 08a.
Terminology acceptance test, n—a test, or series of tests conducted by the procuring agency, or an agent thereof, upon receipt to determine whether an individual lot of materials conforms to the purchase order or contract or to determine the degree of uniformity of the material supplied by the vendor, or both. Compare preproduction test and quali?
Compare coupling agent and primer. See also glue, gum, mucilage, paste, resin, and sizing. These terms are loosely used interchangeably.
Various descriptive adjectives are applied to the term adhesive to indicate certain characteristics as follows: See also adhesion failure and cohesion failure. It is applied to adhesives used in fabricating? See also closed assembly time and open assembly time. A-stage, n—an early stage in the preparation of certain thermosetting resins, in astk the material is still soluble in certain liquids, and fusible.
See also adhesion and bond. In latex adhesives the aastm is also used to describe the joint strength when the adherends are brought together with the adhesive still in the wet state.
B-stage, n—an intermediate stage in the reaction of certain thermosetting resins in which the material swells when in contact with certain liquids and softens when heated, but may not entirely dissolve or fuse. Compare to bulk adhesive.
Compare to bulk adherend. See also curing time and setting time. See also viscosity and viscosity coefficient. D — 08b copolymerization, n—see polymerization. See also joint-conditioning adtm, setting time. Dd907F07; DD14 delamination, n—the separation of layers in a laminate because of failure of the adhesive, either in the adhesive itself or at the interface between the adhesive and the adherend. Some adhesives will bond by bridging without completely?
See also adhesive, glue, n, and resin. Gums are included by some in the category of natural resins.
See also curing time, drying time, and setting time. Compare coldsetting adhesive, hot-setting adhesive, and roomtemperature-setting adhesive. Compare laminate, n and wood laminate. See also adhesive, glue, paste, and sizing. Newtonian behavior, n—the property of a liquid in which its viscosity is constant over d970 stated range of strain rates. E 6, E28; DD14 A Taken f907 part from non-Newtonian behavior, n—the property of a liquid in which its viscosity is not constant over a stated range of strain rates.
A standard test method must be used to obtain 9d07 results. When two or more monomers are involved, the product is called a copolymer. The angle between the members varies with the type of peel test.
Compare adhesive, glue, mucilage, and sizing.

Compare acceptance test and quali? Compare acceptance test and preproduction test. See also vulcanization, n.
See also cure and dry. See also curing temperature and drying temperature. See also novolak and thermosetting. Compare cold-setting adhesive, hot-setting adhesive, and intermediate-setting adhesive. Many adhesives exhibit curvilinear or nonelastic behavior, or both, in which case 9d07 other term, such as secant modulus, may be substituted.
Stress on a non-planar surface varies with the location of the point, depending upon the direction of the application of stress. E 6, E28; DD14; DD14 stringiness, n—the property of an adhesive that results in the formation of? See also legging and webbing.
See also tack range and tacky-dry. Compare legging, stringiness, and webbing. See also A-stage, B-stage, and C-stage. See yield strain and viscosity. If the liquid is deformed more than the yield strain, the underlying elastic network is disrupted and its viscosity is reduced.
The network reestablishes itself in time when at rest. See Newtonian behavior, non-Newtonian behavior, and thixotropy.
All points within the material return to their original d9907, thus showing elastic behavior. If the material is deformed more than the yield strain, some permanent deformation? Part of the energy is consumed in the permanent deformation. Synonym yield value R yield value, n—Synonym yield stress. The year of publication is shown in parentheses following the de? A Addition since previous Volume Curing agent was formerly a cross reference for hardener.
The discussion was revised.
