UL94 Foam Horizontal Burning Tester | ISO 9772 Flammability Testing Equipment for Cellular Plastics Safety Compliance

HongCe HVF‑5A Foam Horizontal Burning Tester is a precision flammability testing instrument built strictly to UL94 and ISO 9772, designed to evaluate horizontal burning performance of low‑density cellular plastics. As a direct manufacturer, HongCe ensures stable performance, reliable test data, full‑process pre‑sales and after‑sales support, helping labs and factories pass safety certifications efficiently.

Safety and compliance are non‑negotiable in material development and quality control. HongCe Foam Horizontal Burning Tester is engineered to deliver accurate, repeatable flammability tests for foam plastics used in packaging, furniture, electronics, automotive interiors, and construction insulation. It precisely measures burning rate, combustion time, self‑extinguishing performance, and flame spread to determine ratings like HBF, HF‑1, HF‑2.

• Fully compliant with UL94 and ISO 9772 for standardized, repeatable test results
• Integrated ignition system with 0.1s delay for stable, complete gas combustion
• Precise flame control: 38±2mm standard blue flame
• Adjustable gas pressure and flow for methane, propane, or mixed gas
• High‑precision timing: 0–9999×0.1s for combustion and self‑extinguishing periods

• UL94: Standard for Tests for Flammability of Plastic Materials for Parts in Devices and Appliances, covering horizontal burning classification for foamed materials
• ISO 9772:2001: Cellular plastics — Determination of horizontal burning characteristics of small specimens subjected to a small flame
• ISO 10093:1998: Standard specification for blast burner used in flammability tests
• ISO 845: Method for density determination of cellular plastics (required for sample eligibility)

• Q1: What materials can this tester evaluate?

  It evaluates cellular plastics with density <250kg/m³ (per ISO 845), including flexible foam, rigid foam, PU foam, EPS foam, and related composite materials.

• Q2: Which standards and flame ratings does it support?

  It fully supports UL94 and ISO 9772, used to classify materials into HBF, HF‑1, HF‑2 levels.
