comma before and after 'i.e.' [abbreviation]: alternative, i.e.,...


New Member
Dear all,

I am wondering if I should enclose i.e. in commas in below sentence or if just one comma before i.e. would be sufficient. Your help is greatly appreciated.

In view of the fact that a test pressure of at least 50 bar would be indicated for bare tanks in this case, the working party favours the first alternative, i.e., reducing the filling ratio to 0.87 kg/l.

Thank you!
