ASTM D2584 Ignition Loss of Cured Reinforced Resins

ASTM D2584 Ignition Loss of Cured Reinforced Resins Scope:

ASTM D2584 test determines ignition loss of cured reinforced resins by evaluating the fiber content remaining after burning. The ignition loss obtained can be considered resin content if only glass reinforcement and organic resin are present in the product.

Test Procedure:

Ignition Loss Test of Cured Reinforced Resins by ASTM D2584 includes conditioning of three specimens of 5 g (2.5 inch × 2.5 inch × thickness) at quality laboratory conditions for 40 hours at minimum. The weight of specimens is then measured on an analytical weighing balance nearest to 0.1 mg. After that, the specimens are placed in pre-weighed and pre-dried ceramic or metal containers and placed in a furnace at 565°C ± 28°C until all carbonaceous materials vanish. Crucibles are then cooled in a desiccator. Finally, ignition loss p is calculated after weighing the crucibles.

Specimen size:

Specimens weighing 5 g of approximate dimension 2.5 inch × 2.5 inch × required thickness

Data:

 The ignition loss percentage is calculated as:

 IL = (w₁ – w₂) / w₁ × 100

 w₁ = Specimen weight 

w₂ = Residue weight

Conclusion:

ASTM D2584 is a standard test method used to determine ignition loss of cured reinforced resins.
