The grade of gold plating follows the Knoop hardness test which was developed by Frederick Knoop and his National Bureau of Standard’s colleagues in 1939 defined by the ASTEM E384 standard. There are four grades: A, B, C, and D. Variables such as environment, temperature, and load can have impacts on testing and are taken into consideration during the examination.

Specifically, Grade D gold plating has a 201 Knoop and over. The Knoop hardness test examines the hardness of more fragile materials or thin sheets. Knoop values usually range from 100-1000 and is an ideal test to understand the limitations of a product on a small sample of material. This hardness allows gold to not only provide its typical corrosion and wear resistance but also can provide the level of stability necessary for the industry and product being made.
