ASTM D5267 Standard Test Method for Determination of Extrudability of Cartridge Adhesives

Get Certified ASTM D5267 Cartridge Adhesive Extrudability Testing

ASTM D5267 testing is beneficial to adhesive manufacturers, cartridge manufacturers, material suppliers, engineers, and maintenance or quality control staff who are assessing the dispensing properties of cartridge adhesives. Technicians identify representative adhesive cartridges and prepare them according to the applicable test requirements. The cartridge is installed in suitable extrusion equipment, and the adhesive is dispensed under the specified conditions. Technicians record the applicable extrusion measurements, including the required force or other specified dispensing characteristics. Analysts examine the recorded information to establish the extrudability of the tested adhesive. The results provide information for comparison of adhesive formulations, production consistency monitoring, cartridge performance assessment, and detection of changes that could have an impact on adhesive application.

• Cartridge Adhesives: Evaluates applicable adhesives supplied in cartridge packaging. 
• Adhesive Extrusion: Determines how the adhesive responds when it is dispensed under specified conditions. 
• Dispensing Characteristics: Provides information about the force or other applicable characteristics associated with adhesive extrusion. 
• Material Comparison: Supports comparison of extrusion characteristics between applicable adhesive materials or formulations. 
• Quality Control: Supports monitoring of adhesive and cartridge dispensing consistency. 

What are the uses of ASTM D5267 testing?

ASTM D5267 provides information about the extrudability and dispensing behavior of cartridge adhesives. The test helps to:

• Determine the extrudability of applicable cartridge adhesives. 
• Evaluate the dispensing characteristics of adhesive materials. 
• Compare different adhesive formulations. 
• Monitor variations between production batches. 
• Identify changes that may affect adhesive application. 
• Support adhesive formulation and product development. 
• Assist in quality control and manufacturing-monitoring activities. 

Which materials can be tested according to ASTM D5267?

ASTM D5267 applies to adhesives supplied in cartridges for which extrudability evaluation is required. Technicians should verify the adhesive type, cartridge configuration, sample condition, and applicable test requirements before testing. The method applies to:

• Cartridge Adhesives: Evaluates applicable adhesives supplied in cartridge containers. 
• Different Adhesive Formulations: Supports comparison of extrusion characteristics between applicable adhesive formulations. 
• Production Samples: Allows representative cartridge adhesives from different production batches to be evaluated. 
• Adhesive Products: Supports evaluation of applicable finished adhesive products intended for cartridge dispensing. 

Why is ASTM D5267 testing important?

The ability of an adhesive to be dispensed consistently can affect the efficiency and quality of an adhesive application process. Adhesives that require excessive extrusion force or display inconsistent dispensing behavior may affect application accuracy and process performance. ASTM D5267 provides a standardized approach for evaluating cartridge adhesive extrudability under controlled conditions. The results help manufacturers and engineers compare adhesive products, monitor production consistency, evaluate dispensing characteristics, and support product development and quality control activities.

ASTM D5267 Testing Process and Data Collection

Technicians identify the cartridge adhesive and prepare representative samples for testing. They inspect the cartridge and verify that the adhesive and cartridge configuration meet the applicable test requirements. The technician installs the cartridge in suitable extrusion equipment and applies the specified dispensing conditions. The adhesive is extruded while the required force or other applicable dispensing measurements are recorded. Technicians record the adhesive identification, cartridge information, test conditions, extrusion measurements, and relevant observations. Analysts review the recorded data to evaluate and report the extrudability characteristics of the cartridge adhesive.

Common Challenges and Troubleshooting

The results of ASTM D5267 can be influenced by the condition of the cartridge, the temperature at which the adhesive is applied, the preparation of the samples, the configuration of the nozzle, the alignment of the equipment, the flow rate of the adhesive during the extrusion process, the consistency of the material, and calibration of the equipment. The technicians should make representative samples of the cartridges and keep the test conditions as specified during the procedure. They should check the extrusion equipment and ensure the appropriate force-measuring system is calibrated and running correctly. When the results are not as expected, the technicians are required to check the condition of the adhesive, the configuration of the cartridge, the test temperature, the setting of the extrusion condition, the setup of the equipment, the measurement system, and the preparation method of the specimen.

• ASTM D5267 produces extrudability-specific results rather than a single overall material-property value.
• Analysts report the applicable extrusion force in the units specified by the selected procedure, such as N or another applicable SI force unit. 
• Where applicable, the report may also include extrusion rate, dispensing distance, or other specified test parameters.
• The report includes adhesive identification, cartridge configuration, specimen condition, applicable test conditions, and the recorded extrusion measurements.
• Systems and analysts can achieve comparable and reliable results by using consistent sample preparation, controlled test conditions, proper equipment setup, and calibrated test equipment.
