Application Summary AI generated
This standard specifies test methods for evaluating the ozone resistance, thermal stability (hot set), and resistance to mineral oil of elastomeric compounds used in cable insulation and sheathing. It is applied in the manufacturing and quality control of electric and optical cables, particularly for products like rubber-insulated wires and cables intended for harsh environments. The tests ensure the long-term durability and safety of cable materials under exposure to ozone, heat, and oil.
