Horizontal Vertical Flame Tester: High-Precision UL94 & IEC Standard Flammability Chamber

Quick Summary

The Horizontal Vertical Flame Tester is an advanced flammability test chamber designed to evaluate the combustibility and fire resistance of plastic materials and electronic components. Engineered in full compliance with international standards such as UL 94, IEC 60950-1, and IEC 60695-2-2, this instrument features a durable stainless steel enclosure, PLC control system, and a high-precision digital timing unit. It provides precise measurements for flame-applying time, afterflame, and afterglow duration to ensure material compliance across electronics, automotive, and polymer industries.

Introduction to Flammability Testing

Evaluating the burning characteristics of plastic materials is critical for ensuring product safety in modern electrical, electronic, and industrial manufacturing. The Horizontal Vertical Flame Tester assesses how solid components react when exposed to a controlled burner flame.

Constructed with a heavy-duty stainless steel enclosure and a large transparent glass viewing window, the unit allows safe observation of flame propagation, afterflame, and heat-remaining times while maintaining high test repeatability and operational stability.
