Sheathing Compound – Tensile Strength (without aging)

This test determines the tensile strength and elongation at break of wire specimens as specified in IEC 60811-1-1. Specimens are pulled at a controlled rate in a universal testing machine until failure occurs, and the force and extension are recorded throughout the test.Tensile strength and elongation are fundamental mechanical properties that indicate the material’s ability […] Read more

Blunt Impact

Section 6.3 of ICEA S-81-570 specifies environmental stress cracking tests per ASTM D1693. Specimens are prepared from completed cable or extrusion material and exposed to a 10% concentration cracking agent solution.The requirement is no cracks for 75°C Wall Type II or III materials. This test identifies insulation materials susceptible to stress cracking in the presence […] Read more

Sharp Impact

Section 6.2 of ICEA S-81-570 specifies six mechanical abuse resistance tests on 1/0 AWG cable with 80-mil insulation. Tests include: Sharp Impact (10 lb-force-inch min), Blunt Impact (40 lb-force-inch), Abrasion (200 cycles to fail), Crush (650 lbs), Puncture (50 lbs), and Scoring (200 cycles to fail).All testing is performed at 25.0 ±5.0°C per Appendix F […] Read more

Suitability of Insulation for Use on AC Circuits in Wet Locations

Section 6.1 of ICEA S-81-570 specifies the wet insulation resistance stability qualification test. Cable specimens at least 10 feet long are immersed in tap water at rated temperature and energized at 600V AC. Insulation resistance is measured after 1, 7, and 14 days, then weekly for 12+ weeks.The stabilization period is determined per ANSI/NEMA WC-53. […] Read more

Insulation Hot Creep and Hot Set

Section 5.3 of ICEA S-81-570 specifies measuring hot creep and hot set of the insulation per ANSI/ICEA T-28-562. For 90°C rated insulation: max 100% elongation (filled) or 175% (unfilled), max 5% set (filled) or 10% (unfilled) at 150°C.The hot creep test verifies adequate crosslinking of the insulation material, which is critical for maintaining dimensional stability […] Read more
