ASTM D635 Rate of Burning and Extent and/or Time of Burning of Plastics in a Horizontal Position

ASTM D635 is a test method used to determine the rate of burning, extent, and time of burning of plastics when tested in a horizontal position. The test is used to evaluate the burning characteristics of materials and is often used in quality control and specification purposes.

Introduction to ASTM D635

ASTM D635 is a standard test method designed to evaluate the rate of burning, extent, and time of burning of plastics when tested in a horizontal position. The method involves measuring the burning rate and time of ignition of a test specimen when subjected to a flame from a Bunsen burner. The results obtained through this method are used for evaluating the fire hazard and fire resistance properties of plastic materials along with the quality control, reliability check, performance evaluation, and specification purposes.

ASTM D635 Test Method

The test method ASTM D635 involves placing the test specimen on a horizontal surface and exposing it to a Bunsen burner flame. The Bunsen burner is adjusted to provide a blue flame. The procedure can be divided into the following steps:

Conditioning and igniting the SpecimenThe specimen is conditioned to a standard temperature and humidity for a specified period of time before testing. The specimen is ignited at one end using the Bunsen burner flame, and the time taken for the flame to ignite the specimen is recorded.
Recording burning rateThe distance between the leading and trailing edges of the flame is measured at specific intervals, and the burning rate is calculated. The extent of burning is measured as the length of the specimen that has been consumed by the flame, and the time of burning is recorded as the time taken for the flame to burn the entire length of the specimen.


ASTM D635 Specimens

Specimen detailsASTM D635 test specimens are flat, rectangular shaped plastics.
Specimen dimensionsThe acceptable specimen thickness for ASTM D635 is between 0.8 to 3.2 mm. The minimum width and length of the specimen is 76 mm and the maximum length is 305 mm.
Specimen preparationThe specimen should be cut from the sample material and conditioned for a minimum of 40 hours at a temperature of 23 ± 2°C and a relative humidity of 50 ± 5%. The edges of the specimen should be free from roughness, nicks, or other imperfections that could affect the test results.

ASTM D635 Results

The results obtained through the ASTM D635 test method include the burning rate, extent, and time of burning of the plastic material. The test is used to evaluate the fire hazard and fire resistance properties of plastic materials and is often used in quality control and specification purposes.

Tests related to ASTM D635

Other ASTM test methods related to the evaluation of fire hazard and fire resistance properties of plastics include ASTM D2863 Standard Test Method for Measuring the Minimum Oxygen Concentration to Support Candle-Like Combustion of Plastics and ASTM E1354 Standard Test Method for Heat and Visible Smoke Release Rates for Materials and Products Using an Oxygen Consumption Calorimeter.
