Full title and description
ASTM D1929-23 — Standard Test Method for Determining Ignition Temperature of Plastics. Laboratory procedure using a controlled hot‑air furnace to determine the flash ignition temperature and the spontaneous (auto) ignition temperature of plastic materials under specified conditions.
Abstract
This test method specifies equipment, specimen preparation, and procedures for measuring the lowest ambient air temperature at which a plastic specimen ignites when exposed to a calibrated hot‑air furnace. Results provide comparative ignition temperatures for materials and support fire‑safety assessments, while noting that ignition temperature alone does not represent the full fire hazard of a material.

Scope
This standard covers a laboratory determination of the flash ignition temperature and spontaneous ignition temperature of plastics using a hot‑air furnace. Values are stated in SI units. The method includes specimen conditioning, apparatus and thermocouple requirements, specified air velocity and heating procedure, and safety cautions regarding hazardous combustion products. The test is intended for comparative ranking of materials, not as a sole criterion for overall fire hazard.
Key topics and requirements
- Definitions of flash ignition temperature and spontaneous (auto) ignition temperature.
- Apparatus: hot‑air furnace design and calibration, thermocouple type and placement, and requirement for specified air velocity.
- Specimen geometry, conditioning (reference to ASTM D618), and mounting in the furnace.
- Controlled heating procedure and criteria for identifying flash ignition and spontaneous ignition events.
- Use of SI units as the standard; precision and reproducibility considerations and interlaboratory study practices.
- Required reporting elements: measured temperatures, test conditions, specimen details, and any deviations from the procedure.
- Safety and environmental precautions for handling combustible gases and combustion products.
- Equivalence and alignment with ISO 871 (noting similarity to ISO 871‑2022, Option 1).
Typical use and users
Used by materials test laboratories, plastics manufacturers, product designers, fire safety engineers, regulatory bodies and certification organizations for product development, quality control, material selection, and comparative evaluation of ignition susceptibility of plastic materials and components.
