We're aware of no such standard. Check with ink suppliers [eg, Conductive Compounds, Coats Circuit Products, Creative Materials, etc] to confirm.

You need to cover the chipped areas with a protectant coating, like epoxy. Look here:http://www.circuittechctr.com/products/115-1322.shtml We have no relationship, nor receive benefit from the company referenced above.
