Introduction to ASTM D2584
ASTM D2584 is a standard test method that measures the ignition loss of cured reinforced resins. The test determines the number of volatile materials that are released from the resin as it decomposes and burns off. This method is commonly used in various industries such as plastics and composites industries and helps assess the quality of cured reinforced resins.
Ignition loss is an important characteristic of cured reinforced resins. It is the measure of the amount of organic material present in a sample. ASTM D2584 provides a standard method for determining the ignition loss of cured reinforced resins.

ASTM D2584 Test Method
The ASTM D2584 test method involves heating a sample of cured reinforced resin in a furnace at a specified temperature for a set period of time. The weight loss of the sample is then recorded and used to calculate the ignition loss. The test is typically performed in two steps, as outlined in the table below.
Conditioning the Sample
The first step of the ASTM D2584 test method involves conditioning the sample to a specified temperature and humidity. The sample is placed in a chamber where it is subjected to a controlled temperature and humidity for a set period of time. This conditioning step is necessary to ensure that the sample is at a consistent moisture content before testing.
Ignition Loss Test
The second step of the ASTM D2584 test method involves heating the sample in a furnace to a specified temperature for a set period of time. The sample is placed in a crucible and heated in a furnace until it reaches a constant weight. The weight loss of the sample is then recorded and used to calculate the ignition loss.
ASTM D2584 Specimens
Specimen Details
The specimen used in the ASTM D2584 test method is a cured reinforced resin sample. The sample is typically in the form of a disc or cylinder and is prepared by curing a resin mixture with a reinforcing material, such as fiberglass or carbon fiber.
Specimen dimensions
The acceptable specimen for ASTM D2584 is a small piece of cured reinforced resin. The sample size is typically between 1 and 3 grams.
Specimen preparation
The specimen is prepared by mixing the resin and reinforcing material together and then curing the mixture to form a solid sample. The sample is then cut or machined into the desired shape and size.
ASTM D2584 Results
The results of the ASTM D2584 test method are reported as the ignition loss of the cured reinforced resin sample. The ignition loss is calculated as the percentage of weight loss of the sample during the heating process. The results are used to evaluate the quality of the cured reinforced resin and to ensure that it meets the necessary specifications for its intended use.
Tests related to ASTM D2584
ASTM D2584 is related to several other ASTM standards that measure the properties of plastics and composites. These standards include ASTM D638 for the tensile properties of plastics, ASTM D790 for the flexural properties of plastics, and ASTM D7264 for the flexural properties of reinforced plastics. These tests are commonly used in conjunction with the ASTM D2584 test method to fully evaluate the properties of cured reinforced resins.
Use of ASTM D2584 in Various Industries
The standard is widely used in the aerospace, automotive, and electronic industries to determine the heat-resistance and fire-retardant properties of materials. This entails testing the combustion behavior of polymers and composites pertaining to safety during rule compliance and their performance needs. This can thereby maximize the designs of products.
Materials Commonly Tested with ASTM D2584
Common materials tested include several types of thermoplastics, thermosets, and composite materials that must be flame-resistant. Many different types of polymers have been evaluated through this test method, including polycarbonate, polyamide, polyethylene, and polyester resins, as well as some fiberglass-reinforced composites.
Common Challenges and Troubleshooting in ASTM D2584 Testing
Testing faces some difficulties related to uniform preparation of the specimen and consistency in heating. Changes in sample dimension, surface, etc, may affect the result. Troubleshooting includes standardizing the procedure for cutting the specimens, calibrating heating equipment, and conducting preliminary tests to ensure better reliability and accuracy.
Thermogravimetric Analysis Process and Data Collection
It is the process of determining the inorganic content in reinforced plastics by thermogravimetric analysis by burning off all organic components. It measures inorganic content, followed by heating the specimen to a high temperature in a muffle furnace, weighing it before the test and calculating the percentage of organic and inorganic material.
Importance of ASTM D2584
It is an important test for determining the composition of reinforced plastics, the level of inorganic filler content, and guaranteeing material performance and quality. It is thus essential for the aerospace, automotive, and construction branches, ensuring strength in mechanical efficiency, stability in thermal conditions, and endurance to definite conditions.
