This Standard sets out two methods, the macro method and the micro method, for the assessment of the distribution of cracks and pores in electroplated coatings of chromium. The macro method is suitable for a visual assessment of the crack pattern in microcracked coatings whereas the micro method enables an accurate count of very fine crack and pore patterns.

The macro method is suitable for a visual assessment of the crack pattern in microcracked coatings whereas the micro method enables an accurate count of very fine crack and pore patterns.NOTE: 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.
