Scope

This Standard sets out the method for assessing the tarnish resistance of electroplated coatings that form visible sulfides or for estimating porosity in non-tarnishing deposits on metals that form visible sulfides.
The method is suitable for assessing the efficacy of tarnish preventing treatments applied to coatings of silver, brass or copper and for assessing the degree of porosity in gold and gold alloy coatings on copper alloy basis metal.
NOTES:
1 Nickel and tin are not affected by thioacetamide vapour.
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.
