SPECIAL RECOMMENDATIONS

          Methyl alcohol should not be used in the pressure testing of tanks since failure can occur due to stress-corrosion cracking.

          Should have very low interstitial content (i.e. oxygen, hydrogen, nitrogen) to avoid hydrogen embrittlement, etc. This is particularly important when there is a need for welding or heat testing.
