This Standard sets out a method for the determination of the degree of porosity in gold and gold-alloy electroplated coatings on copper base, nickel and tin-nickel alloys. This method utilizes the passage of current through a gelatinized electrolyte.
NOTES:
1 The method may be considered a variant of electrography which is usually carried out with the aid of paper soaked in a special test solution. Compared with electrography, this method has some advantages, e.g. it can be used on curved surfaces with minimum spreading of the coloured spots from the pores.
2 The test procedures described in this Standard do not necessarily include all of the precautions required to satisfy health and safety aspects. Care should be taken to ensure that the procedures are carried out only by people who have received suitable training. Guidance in the handling and use of hazardous chemicals is given in AS/NZS 2243.1 and AS/NZS 2243.2.
