Rosslyn, VA —The

National Electrical Manufacturers Association (NEMA)

reaffirmed, on Oct. 15, the following industrial control and system standards for certain controllers, control systems, test procedures, and motor control centers:

The NEMA reaffirmed standards are: ICS 2, Part 9-2002 (R2007) AC Vacuum-Break Magnetic Controllers Rated 1500 Volts AC; ICS 5, Annex F-2002 (2007) Industrial Control and Systems: High-Pressure Power Wash Test Procedure for Self-Contained Control-Circuit Devices; ICS 18-2001 (R2007) Industrial Control and Systems: Motor Control Centers; and ICS 18-2001 (R2007) Industrial Control and Systems: Motor Control Centers.

ICS 2, Part 9-2002 (R2007) applies to magnetically operated, full-voltage, vacuum-break, non-combination controllers rated 1,500 V for both motor and non-motor loads. It may be downloaded at no charge, and a hard copy or electronic copy purchased for $68.

ICS 5, Annex F-2002 (2007)

relates specifically to high-pressure power wash procedure requirements for proximity switches, limit switches, and panel-mounted control devices that include pushbuttons, pilot lights, and selector switches. It may be downloaded at no charge, and a hard copy or electronic copy purchased for $48.

ICS 18-2001 (R2007)

applies to three-phase 50- and 60-hertz motor control centers rated not more than 600 Volts ac. It may be downloaded at no charge, and a hard copy or electronic copy purchased for $64.

ICS 19-2002 (R2007) provides guidelines for representation of devices on diagrams and drawings in a standardized manner. It may be downloaded at no charge, and a hard copy or electronic copy purchased for $75.
