Identification F326-96
Standard Test Method for Electronic Measurement
For Hydrogen Embrittlement from Cadmium-

Electroplating Processes



This test method covers an electronic hydrogen detection instrument procedure for measurement of plating permeability to hydrogen. This method measures a variable related to hydrogen absorbed by steel during  plating and to the hydrogen permeability of the plate during post plating baking. A specific application of this method is controlling cadmium-plating processes in which the plate porosity relative to hydrogen is critical, such as cadmium on high-strength steel.

Identification F519-13
Standard Test Method for Mechanical Hydrogen Embrittlement
Evaluation of Plating/Coating Processes and Service  Environments



This test method describes mechanical test methods and defines acceptance criteria for coating and plating processes that can cause hydrogen embrittlement in steels. Subsequent exposure to chemicals encountered in service environments, such as fluids, cleaning treatments or maintenance chemicals that come in contact with the plated/coated or bare surface of the steel can also be evaluated.

Standard Test Method for Measurement of Hydrogen Embrittlement Threshold in Steel by the Incremental Step  Loading Technique


Scope This test method establishes a procedure to measure the susceptibility of steel to a time-delayed failure such as that caused by hydrogen. It does so by measuring the threshold for the onset of subcritical crack growth using standard facture mechanics specimens, irregular-shaped specimens such as notched round bars, or actual product such as fastener springs or components as identified in SAE J78, J81 or J1237.
