Standard Test Method for Flame Height, Time of Burning, and Loss of Mass of Rigid Thermoset Cellular Plastics in a Vertical Position

SIGNIFICANCE AND USE
5.1 Tests made on rigid cellular materials in accordance with the conditions described by this test method can be of considerable value in comparing their burning characteristics.  
5.2 This test method has been applied to flexible cellular materials and other plastics, but no detailed studies have been conducted to determine its general applicability to these materials.  
5.3 In this procedure, the specimens are subjected to one or more specific sets of laboratory test conditions. If different test conditions are substituted or the end-use conditions are changed, it is not always possible by or from this test to predict changes in the fire-test-response characteristics measured. The results are therefore valid only for the fire-test-exposure conditions described in this procedure.
SCOPE
1.1 This is a fire-test-response standard. This test method covers a small-scale laboratory screening procedure for comparing relative extent and time of burning and loss of mass of rigid thermoset cellular plastics. This test method is to be used solely to establish relative burning characteristics.  
1.1.1 This test method shall not be used for materials that drip or melt under the test conditions.  
1.2 During the course of combustion, gases or vapors, or both, are evolved which are potentially hazardous to personnel. Adequate precautions shall be taken to protect the operator.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. A specific precautionary statement is given in 1.2.  
1.4 This standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of materials, products, or assemblies under actual fire conditions.  
1.5 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.
Note 1: There is no known ISO equivalent to this standard.

Overview

ASTM D3014-19a is the Standard Test Method for Flame Height, Time of Burning, and Loss of Mass of Rigid Thermoset Cellular Plastics in a Vertical Position. Developed by ASTM International, this fire-test-response standard provides a small-scale laboratory screening procedure to compare the relative burning characteristics of rigid thermoset cellular plastics. Specifically, it quantifies three main fire behavior metrics: flame height, time of burning, and mass loss when the plastic specimens are exposed to a direct flame in a vertical orientation.

This test is essential for manufacturers, quality control laboratories, and material specifiers seeking consistent methodologies to assess the flammability of rigid thermoset cellular plastic materials under controlled laboratory conditions. While primarily designed for rigid materials, note that this method should not be used for materials that drip or melt during testing.

Key Topics

  • Burning Characteristics: The method provides comparative data on the extent and time of burning, as well as the percentage of mass retained after the fire exposure.
  • Test Procedure: Specimens are ignited in a vertical orientation using a standard laboratory burner. Measurements include:
    • Maximum flame height
    • Total time burning until extinction
    • Mass of specimen before and after testing
  • Applicability: The results are specific to the described laboratory exposure conditions and may not directly predict fire behavior in end-use situations or under other fire scenarios.
  • Safety Precautions: Combustion of plastics releases potentially hazardous gases and vapors. Proper safety, health, and environmental practices are critical. The user is responsible for determining regulatory applicability and ensuring the safety of personnel and facilities.
  • Limitation: This standard should not be applied to materials that drip or exhibit significant melting during burning.

Applications

ASTM D3014-19a is widely used for quality assurance, research, and product development involving rigid thermoset cellular plastics. Common practical applications include:

  • Material Comparison: Enables consistent and repeatable comparison of flammability performance among different plastic formulations or batches.
  • Product Development: Supports material selection for applications where flame resistance, minimized burning duration, and reduced mass loss are critical performance indicators.
  • Regulatory Documentation: Used to provide objective fire reaction data for regulatory compliance or product safety documentation.
  • Quality Assurance: Helps manufacturers and laboratories assess batch consistency and ensure products meet specified fire performance criteria.

Industries benefiting from this standard include construction, automotive, electronics, appliance manufacturing, and any sector where fire behavior of rigid foam plastics is a concern.
