• Electrical Resistance

  • NE 001/97: National Standard of Electrical Resistance

• Electrical Capacitance

  • NE 014/98: National Standard of Electrical Capacitance

• Time and Frequency

  • NE 004/97: National Standard of Time and Frequency

Other Standards (Pending National Recognition)

• AC Power and Energy
  • OE 032: Other Standard of AC Power and Energy at 50 Hz
