Flame Retardant Tester
Category：Material Combustion Tester
Introduction
The Flame Retardant Tester for Synthetic Sports Track Surface Materials is designed to evaluate the flame resistance of horizontal synthetic track surfaces under controlled flame exposure. It is developed according to GB/T 14833-2011, Appendix D, and provides precise and repeatable assessment of surface burning characteristics for quality control, R&D, and regulatory compliance of synthetic track materials.
Application
This tester is widely used for:
(1) Evaluating flame resistance of synthetic running track layers in schools, sports facilities, and stadiums.
(2) Quality control of PU, rubber, or composite sports surface materials before installation.
(3) Research and development of flame-retardant coatings and additives for synthetic track materials.
(4) Testing surface layers of athletic tracks, gym flooring, and playground synthetic mats.
(5) Regulatory compliance testing according to national and international flame resistance standards.
Tested products include: PU track layers, EPDM/rubber track surfaces, multi-layer composite track sheets, and other horizontal synthetic surfaces.
Compliance Standards
(1) GB/T 14833-2011 — Synthetic material track surfaces — Appendix D: Flame retardant testing method (China national standard)
(2) ISO 11925-2 — Reaction to fire tests — Ignitability of building products exposed to direct flame
(3) EN 13501-1 — Fire classification of construction products and building elements
(4) Relevant ASTM, UL, or IEC standards for flame resistance testing of polymer and composite materials
