ASTM D4363-22 PDF

Overview

ASTM D4363-22: Standard Specification for Thermoplastic Chlorinated Polyethylene (CPE) Jacket for Wire and Cable is an internationally recognized standard developed by ASTM International. This specification details the requirements for thermoplastic chlorinated polyethylene (CPE) compounds used as the outer covering, or "jacket," for electrical cables. These CPE jackets are valued for their flexibility, durability, and resistance to environmental factors such as sunlight and weather exposure. The standard is critical for manufacturers, designers, and installers of electrical wiring and cabling systems that require reliable performance in demanding environments.

Key Topics

• Material Suitability: Specifies CPE compounds as suitable jacketing materials for electrical cables, particularly in installations where operating temperatures are above –35 °C.
• Physical Properties: Details the required physical characteristics of CPE jackets, including:
  • Minimum tensile strength and elongation at rupture values
  • Performance after aging (air oven and oil immersion)
  • Resistance to heat distortion and cold bend (no cracks at –35 °C)
• Electrical Performance: For cables rated 2001 to 5000 V phase-to-phase, includes provisions for minimum surface resistivity and U-bend test results.
• Sunlight and Weather Resistance: Outlines testing procedures and minimum retention of original tensile properties following prolonged exposure to carbon-arc light, demonstrating strong UV resistance and durability in outdoor environments.
• Testing and Sampling: References standardized test methods for evaluation of material performance, ensuring consistent quality and compliance.

Applications

The ASTM D4363-22 standard is widely used in the manufacturing and assessment of electrical cable jackets for various sectors, including:

• Industrial Facilities: Electrical cables in harsh industrial environments benefit from CPE jackets that resist heat, oil, and mechanical stresses.
• Outdoor Installations: Power and control cables exposed to sunlight and weather are protected by CPE’s UV and weather resistance, meeting stringent durability requirements.
• Construction and Infrastructure: CPE jacketing is employed in commercial and infrastructure projects requiring cables to maintain flexibility and integrity under severe temperature or environmental conditions.
