(Specification)Standard Specification for Anaerobic Single-Component Adhesives (AN)
Standard Specification for Anaerobic Single-Component Adhesives (AN)
ABSTRACT
This specification establishes the requirements for single-component anaerobic adhesives suitable for locking, sealing, and retaining threaded or cylindrical assemblies. It is intended to be a means of classifying the adhesives, and does not address engineering design purposes. The adhesives are cured to a solid state when confined between closely fitting active metal surfaces. Materials shall undergo test procedures and conform accordingly to the following requirements: ultraviolet fluorescence; color and workmanship; flash point; storage stability; toxicity; solvent resistance; hot strength; heat aging; cold strength; lubricity; fluid tightness; wicking; viscosity; speed of cure; prevailing torque strength (strength at standard conditions); and qualification of primers.
SCOPE
1.1 This specification covers single-component anaerobic adhesives suitable for locking, sealing, and retaining threaded or cylindrical assemblies. The adhesives are cured to a solid state when confined between closely fitting active metal surfaces.
1.2 This specification is intended to be a means of classifying anaerobic adhesives. It is not intended for engineering design purposes.
1.3 This specification is intended to replace Military Specifications MIL-S-22473, MIL-S-46163, and MIL-R-46082.
1.4 The values stated in SI units are to be regarded as the standard.
1.5 The following safety hazards caveat pertains only to the test methods portion, Section 7, of this specification. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

3. Terminology
3.1 Definitions—Some terms in this specification are defined in Terminology D907.
3.1.1 activemetal surface, n— relative to anaerobicadhesives,ametalsurfacethatinitiatestheformationoffreeradicalswithin
anaerobic adhesives.
3.1.2 anaerobic adhesive, n—an adhesive that is kept in the uncured state by oxygen, as in air, and that cures in the absence
of oxygen when exposed to metal ions, especially copper or iron.
3.1.3 Newtonian behavior, n—the property of a liquid in which its viscosity is constant over a stated range of strain rates.
(Compare non-Newtonian behavior.)
3.1.4 non-Newtonian behavior, n—the property of a liquid in which its viscosity is not constant over a stated range of strain
rates. (Compare Newtonian behavior.)
3.1.5 thixotropy, n—in a liquid, the property of thinning when subjected to strains greater than the yield strain and of
rethickening with time upon subsequent rest.
3.1.5.1 Discussion—The liquid must exhibit yield to be thixotropic. 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.
3.2 Definitions of Terms Specific to This Standard:
3.2.1 breakaway torquebreakaway torque, n—the initial torque required to break the bond, measured at the first movement
between the nut and the bolt, when unscrewing an unseated assembly.
3.2.2 prevailing torque, n—the torque measured at 180° rotation of the nut.
3.2.2.1 Discussion—Prevailing torque was originally defined in MIL-S-46163 and MIL-S-22473 as the average of the four
torques measured at 90, 180, 270, and 360° rotation of the nut. Studies have shown that the torque measured at 180° rotation of
the nut is statistically equivalent to the average of the torque measured at the four ⁄4 turns. Since measuring the torque at the one
angle of rotation is more efficient, prevailing torque is most often defined as the torque measured at 180° rotation of the nut.
However, for purposes of this specification, the definition of prevailing torque as the average of the four torques measured at 90,
180, 270, and 360° rotation of the nut is also acceptable.
