IMPORTANT CORRECTIONS TO FR PROTECTION COLUMN, SEPT ISSUE
The September 2017 issue of ISHN contained errors in the FR Protection column (page 20) and posted online as the September FR Protection column:
- NEVER use the 1998 version of ASTM F1506. It was pre-arc rating and is commonly cited by incorrect clothing because it only had a VERTICAL FLAME test. Many melting materials will pass that standard.
- ASTM F1891 has no 1998 version. It was not published until the last part of 1999 so the first version number is 1999a.
- The current versions of these important standards are as follows: ASTM F1891-12 and ASTM F1506-15.
- Arc Rated is the proper term. Arc Resistant is old and now only properly used of equipment that does not allow out arc flash energy onto a worker.
- Corrections provided by Hugh Hoagland, senior consultant, ArcWear.
