ASTM B764-04(2021) 《Standard Test Method for Simultaneous Thickness and Electrode Potential Determination of Individual Layers in Multilayer Nickel Deposit (STEP Test)》 Related products
This standard describes a test method for determining the thickness of each layer in multilayer nickel platings and their electrode potential difference. Direct measurement of platings thickness and potential difference by anode disbonding at constant Current density. These data help evaluate the corrosion resistance of the nickel layer. This method is suitable for mass assurance of platings in production and can reflect the corrosion resistance of the nickel layer, but the interpretation and evaluation of the results should be determined by negotiation between the buyer and the seller.
