ASTM D1929 Test Lab
When plastics ignite and burn, the heat, flames, and gases released can result in catastrophic loss of life and property. For this reason, the “Standard Test Method for Determining Ignition Temperature of Plastics” — referred to as ASTM D1929 — was developed.
This test specifically benefits companies in the construction, engineering and related materials manufacturing sectors that are required to use plastics that are in full compliance with building regulations, such as the International Building Code — or IBC — as well as more localized ordinances like the Florida Building Code — or FBC — and High Velocity Hurricane Zone — HVHZ. As a matter of fact, in any Florida project that uses plastic, the plastic in question must pass ASTM D1929.

ASTM D1929 — Test Procedures
Besides regulations, knowing how a particular plastic responds to heat and flames is simply prudent for builders, suppliers and manufacturers. Understanding the relative safety of plastic is determined according to the following ASTM D1929 process:
- Specimen Restrictions: First, an appropriately sized specimen must be supplied. For plastics with a density of more than 100 kilograms per cubic meter, a specimen of three grams is necessary. For plastics in sheet form, sheets of 20 millimeters x 20 millimeters are required to be stacked atop one another until a total mass of three grams is attained. For cellular plastics with a density of fewer than 100 kilograms per cubic meter, a block of 20 millimeters x 20 millimeters x 50 millimeters should be supplied with any of its outer skin removed.
- Testing Procedure: Next, the properly sized specimen is lowered into the vertical tube of an ignition furnace with a controlled hot air supply. A technician keeps careful watch looking for any signs of glowing, flaming, explosion, combustion or a rapid increase in temperature. The test lasts for 10 minutes or until ignition occurs. If no ignition occurs, the test is repeated with a fresh sample piece at a higher temperature.
ASTM D1929 — The Results
Performed under the watchful eye of a trained VTEC technician, ASTM D1929 determines two temperatures that are vital to understanding a particular plastic’s safety levels:
- Spontaneous Ignition Temperature or Self-Ignition Temperature: Referred to as SIT, the spontaneous or self-ignition temperature is the lowest temperature at which the test piece self-ignites without the existence of an added flame or external source of ignition.
- Flash Ignition Temperature: Referred to as FIT, the flash ignition temperature is the lowest temperature at which sufficient gases are produced to be flammable and ignite with exposure to an externally supplied ignition source such as a small pilot light.
