ASTM F326 describes a procedure for measuring plating permeability to Hydrogen using an electronic hydrogen detection instrument. It evaluates a variable linked to Hydrogen absorbed by steel during plating and post-plating baking. Using Cadmium-Electroplating processes for the measurement. ASTM F326 (Standard Test Method for Electronic Measurement for Hydrogen Embrittlement From Cadmium-Electroplating Processes) test method provides a quantitative control value for cadmium plate porosity that may be utilized to regulate the cadmium plating process and the condition of cadmium-plated hardware. It is pivotal during plating, as some of the Hydrogen penetrates the components. If the absorbed hydrogen level is high enough to cause embrittlement in high-strength steel, it is eliminated by baking portions after plating to release this Hydrogen. It is used in the plating process for troubleshooting, research, and development to determine the effects on plate porosity, the manufacturing industry, and steel plants.

What is ASTM F326?
ASTM F326 Equipment and Sample Preparation Guide
The test is conducted using an electronic hydrogen detection instrument. ASTM F326 test specimens are hydrogen metals that are 0.0001 to 0.0010 in. thick.
What are the Testing Procedure and Requirements for ASTM F326?
For plate porosity, there is no benchmark. A section of probe shell is electroplated and then baked; for this purpose, two ovens must be utilized, with testing alternating between them. Data from the ovens are compared to confirm that no equipment has changed.
ASTM F326 Analysis Results and Interpretation
The values are stated in SI units, which are to be regarded as the standard. The pressure for Hydrogen is measured in
p = ρgh
Where,
the height is h,
density is ρ,
gravity is g
