[MW:14889] RE: 14886] Diffusible Hydrogen Test of Low Hydrogen Electrode

Biplab,
 
Design basis codes  e.g Sec-VIII, does not call for this requirement.However depending on the intended end use of the electrodes(structural or pressure vessels) this requirement is a "good engineering" practice and should be recorded in the electrode MTR.
 
Look through Sec-II, Pt-C SFA 5.5 for clarifications.
 
Thanks.

Subject: [MW:14886] Diffusible Hydrogen Test of Low Hydrogen Electrode

Dear Experts,

I have a doubt,
Is it mandatory to check the diffusible hydrogen test for every batch of Low Hydrogen electrode as per sec-II part c.
Please give me the code reference.
