scope:

This guide provides recommendations for red stripe and raised ridge identification markings on insulating and semiconducting linear low density polyethylene (LLDPE), medium density polyethylene (MDPE), high density polyethylene (HDPE) and polyvinyl chloride (PVC) jacketed underground power cables, and HDPE duct containing jacketed or unjacketed underground power cables. The red stripe recommendations include the number of stripes, color, width, thickness, retention characteristics, physical properties, storage criteria, and testing methods. The raised ridge recommendations include physical properties, width, height, and circumferential spacing. It is the intent of this guide to provide a minimum level of physical, chemical, and color durability on red stripes used to identify underground power cables and ducts.
