"These requirements cover electrochemical capacitors for use in equipment such as electronic products@ uninterruptible power supplies@ emergency lighting@ engine starting@ and power equipment. These energy storage capacitors@ also known as ""electric double layer capacitors""@ ""ultracapacitors""@ ""double layer capacitors"" or ""supercapacitors"" consist of either individual capacitors or multiple series and/or parallel connected capacitors with or without associated circuitry. These requirements do not cover electrochemical capacitors for use in hazardous (Classified) locations."
