ASTM D5113 Adhesive Attack Testing on Rigid Cellular Foam
Rigidity of Cellular Polystyrene (RCPS) foam cavitation damage is measured using the ASTM D5113 test method when an adhesive is used to bond this substrate. This would help the end-user decide which adhesive to use with the RCPS foam.

Overview
ASTM D5113 evaluates the effect of adhesives on rigid cellular foam by determining whether the adhesive causes degradation, distortion, or structural damage to the foam material. It is commonly used to assess compatibility between adhesives and foam substrates before application in bonded assemblies.
This test is critical for ensuring that adhesives do not chemically or physically attack foam structures, which could compromise insulation, strength, or dimensional stability. It helps manufacturers select suitable adhesive systems, ensuring long-term performance and preventing premature failure in foam-based applications.

Test Process
Specimen Preparation
Rigid foam samples are cut and conditioned as per standard requirements.
1Adhesive Application
Adhesive is applied uniformly on the foam surface under controlled conditions.
2Conditioning Period
Specimens are allowed to react for a specified time to observe interaction effects.
3Visual Evaluation
Foam is inspected for signs of attack such as shrinkage, softening, or distortion.

Frequently Asked Questions
ASTM D5113 is used to evaluate whether an adhesive causes damage to rigid cellular foam. It helps determine compatibility by identifying chemical or physical attack, ensuring that the adhesive will not degrade or weaken foam materials during application.
Incompatible adhesives can dissolve, shrink, or weaken foam structures. This affects insulation properties, strength, and dimensional stability. Testing ensures that the adhesive maintains foam integrity and prevents long-term failure in bonded systems.
Common signs include foam softening, shrinkage, surface distortion, discoloration, or complete dissolution. These effects indicate chemical incompatibility and potential failure in real applications.
The test is qualitative and does not provide numerical data. It may not capture subtle chemical interactions, so it is often used alongside other tests for comprehensive material evaluation.
Following ASTM D5113 ensures standardized procedures and consistent results. It allows reliable comparison across materials and laboratories, supporting quality assurance and regulatory acceptance in industrial applications.
