Swedish Chimney – Vertical Cable Fire Test Apparatus for Flame Spread Evaluation

The Swedish Chimney is a fire-testing apparatus designed for evaluating the fire resistance and flame-spread behavior of single vertical electric cables as per standard IS 10810 (Part 61) and SS-424-1475. With a robust vertical tube length of 800 mm, this equipment replicates real-world fire exposure conditions to determine how cable materials perform under elevated temperatures and direct flame contact.

Built to support fire-safety compliance, the Swedish Chimney helps assess how cables withstand thermal stress, heat exposure, and the potential spread of flames. Its controlled test environment allows manufacturers and quality-control laboratories to evaluate combustion characteristics, ensuring cable systems meet essential fire-performance requirements.

Ideal for R&D, certification, and routine QA testing, the SC-261 provides reliable and repeatable results, making it an essential component in evaluating fire behavior of electrical cables and flue-related materials.
