Standard Practice for Determining Electrolytic Corrosion of Copper by Adhesives

Importancia y uso:

5.1 Adhesives can be exposed to both electrical potential and humidity in many electrical and electronic applications. It is therefore desirable to provide a means of examining the corrosive tendencies of certain adhesives towards metals.

5.2 Although electrolytic corrosion is a direct result of ionic conduction in the adhesive, the nature of the exposed metals will have a bearing on both the severity of metal attack and the visibility of corrosion products. Because it gives a visual indication of corrosion and because of its widespread use in electrical circuits, copper is used in this practice. However, this would not preclude the use of other metals for specific interests.

5.3 This procedure is a subjective test in that determinations of the presence of corrosion is based on a visual inspection for a green discoloration or other evidence of corrosion.
