MODUK DEF STAN 61-012 PART 06 PDF

The equipment wire specified herein is for the internal wiring of electronic and other equipment. They are insulated with PVC, Polyethylene or Silicone Rubber.

The upper temperature limits in the above table refer to maximum continuous temperature of the conductor due to the combination of ambient temperature and temperature rise due to current flow. The lower value may be subjected to slight flexing during normal operating life.

Historic cables meeting the requirements of Defence Standard 61-012 Pt 6 have not been tested for compliance with Defence Standard 07-247 and are therefore prohibited from use in submarines and ships. Future design requirements shall give consideration to tests detailed in DS 07-247 and if those tests are not viable, then agreement shall be sought from Authority that they will not be completed. Agreement shall be provided in writing from the appropriate Authority.

NOTE

Current carrying capacities will depend on circumstances but for general guidance the quoted current values will give a temperature rise of about 15 °C in ambient temperatures up to 70 °C for single, freely ventilated, insulated wires. Different values will apply when equipment wires are bunched.
