System Architecture & Testing Workflow of SPCZ-06 Foam Tester
Standardized Testing Workflow:
- Horizontal Method (ISO 9772 / GB/T 8332): Place the foam specimen horizontally on the steel-wire mesh support. Position the wing-top burner and apply the flame for 60 seconds. Record flame extent, burning duration, and calculate horizontal burning rate.
- Vertical Method (ASTM D3014 / GB/T 8333): Fix the rigid foam sample vertically inside the glass-fronted chimney. Apply the burner flame to the lower end for 10 seconds. Observe flame height, extinguish time, and weigh the residual sample to compute mass loss percentage.
Target Customer Applications:
- Rigid polyurethane (PU) and expanded polystyrene (EPS) thermal insulation board producers.
- Flexible foam manufacturers for automotive seats, mattresses, and furniture cushioning.
- Third-party polymer testing laboratories, UL compliance centers, and research organizations.
SPCZ-06 Plastic Foam Vertical & Horizontal Burning Tester FAQ
Q1: What is the main difference between horizontal and vertical foam burning tests?
A: The horizontal method (ISO 9772 / UL 94 HBF) evaluates flame spread rate across low-density or flexible foam samples on a wire mesh during 60 s flame exposure. The vertical chimney method (ASTM D3014) assesses rigid foam flame height and residual mass percentage following a 10 s ignition.
Q2: Can this tester perform UL 94 horizontal foamed material tests (HBF, HF-1, HF-2)?
A: Yes. The 9.5 mm wing-top Bunsen burner, specimen support mesh, and timing system meet the equipment requirements for UL 94 foamed plastic classification tests.
Q3: What gases can be used for combustion fuel in SPCZ-06?
A: The machine operates with industrial methane (≥98% purity), propane (94 ± 2 MJ/m³), or standardized natural gas mixtures with a calorific value of 37 ± 1 MJ/m³.
