Flame Retardance Test Apparatus for Bunched Cables

(Vertical Flame Propagation Test)

The Flame Retardance Test Apparatus for Bunched Cables is designed to evaluate the flame propagation characteristics of vertically mounted bunched cables when subjected to a standardized flame source. The apparatus complies with IEC, IS and international standards and is widely used by cable manufacturers, test laboratories, and certification bodies.

Applicable Standards

  • IEC 60332-3-10

  • IS 10810 (Part 62)

  • UL 1685

Principle of Test

A bundle of insulated cables is mounted vertically on a ladder inside a metallic chamber and exposed to a controlled flame for a specified duration. After the flame application, the extent of flame spread and damage height is measured to determine compliance with the specified standard.
