Ignitability of Upholstered Furniture

This is some text inside of a div block.

The DNG Ignitability of Upholstered Furniture Test System is designed to assess the fire ignition risk of materials used in upholstered seating—cover fabrics, fillings, and combinations thereof—under standardized conditions. This test evaluates susceptibility to ignition from cigarette smoldering, small flames, and match-equivalent sources.

As part of our fire testing equipment portfolio, DNG Technologies offers this system to laboratories, furniture manufacturers, and certification bodies to ensure compliance with international standards and improve safety in residential, commercial, and public seating applications.

Features & Technical Specifications

Product Overview & Purpose

This test method quantifies the ignitability behavior of upholstered furniture materials when subjected to ignition sources such as smoldering cigarette (EN 1021-1 / ISO 8191-1) and match or small flame ignition (EN 1021-2 / ISO 8191-2). RISE+2RISE+2

It helps determine how a material combination (cover plus filling) responds—whether flames or smoldering propagate, whether damage spreads beyond acceptable limits, or whether ignition extinguishes safely. RISE+2RISE+2

This test is widely used for seating in public occupancies, hotels, institutions, and furniture for commercial and residential markets. measurlabs.com+1

Standards & Compliance

  • EN 1021-1 / ISO 8191-1 — Ignition by smoldering cigarette (test in the junction of seat and back) RISE+2RISE+2

  • EN 1021-2 / ISO 8191-2 — Ignition by match / small flame (gas flame / match equivalent) RISE+1

  • BS 5852 — Methods of test for assessment of ignitability by smoldering and flaming sources Eurofins+2NIST Publications+2

  • ASTM E1537 — Standard test method for fire testing of upholstered furniture; measures heat release rate, smoke, gas outputs under flaming conditions ASTM International | ASTM

  • California TB 117-2013 / 16 CFR Part 1640 — Smolder resistance requirements for upholstered furniture in the U.S. eCFR+1

Features & Technical Specifications

Key Features:

  • Modular test rig for seat-back junction simulation

  • Adjustable ignition sources (cigarette holder, burner tube)

  • Controlled airflow and ventilation in test chamber

  • Timers and sensors to record ignition, smoldering, flaming durations

  • Visual & video monitoring of test progression

  • Automated data capture: char length, after-flame time, extent of damage

Technical Parameters (Indicative):

  • Cigarette ignition test: exposure time 1 hour; no continuing smoldering allowed beyond that period. bhgs.dca.ca.gov+3RISE+3RISE+3

  • Flame ignition test: ignition flame applied for 15–20 s, observe flaming and smolder behavior; no flaming allowed to continue more than 120 s after flame removal. RISE+1

  • Maximum charring allowed: Typically ≤ 100 mm radius from ignition point in lateral directions (excluding upward). RISE+1

  • Specimen setup: Seat-back junction mock-up with cover and filling materials assembled to simulate real upholstery geometry. RISE+1

  • Conditioning: Samples conditioned (e.g. 21 ± 3 °C, < 55% RH) before testing. bhgs.dca.ca.gov+2RISE+2

Applications & Use Cases

  • Furniture manufacturing: Verify upholstery safety and compliance for sofas, chairs, public seating

  • Certification & testing labs: Offer compliance reports for EN, ISO, ASTM, TB standards
