17、Committee on National Connector Standards) 1 Introduction 1.1 Scope This standard establishes 2 methods for determining the total amount of extractable ionic contamination on the surface of an electrical connector or socket assembly or component. 1.1.1 Method A, Ionography A test method for quantify
18、ing the extractable ionic contamination on the surface of an electrical connector or socket assembly or component using an ionograph contamination measurement system as determined in sodium chloride (NaCl) equivalents. 1.1.2 Method B, Ion chromatography A test method for quantifying and identifying
19、the extractable ionic species on the surface of an electrical connector or socket assembly or component using an ion chromatograph system. Ion chromatography results are reported as parts per million as ionic species. 1.2 Object The object of this test procedure is to determine the amount of ionic c
20、ontamination that may be present on the surface of a connector or socket assembly or component (either plastic or metallic). The source of the contamination may be in the materials of construction or in residues from manufacturing processes. If excessive, the reliability of electronic equipment util
21、izing the connector or socket may be compromised. 1.3 Definitions 1.3.1 Total ionic contamination Soluble ionic species such as inorganic salts or weak organic acids 1.3.2 Connector or socket assembly Functional part consisting of conjoined components.
