ASTM D624
Testing Method to Evaluate Tear Strength of Vulcanized Rubber and Thermoplastic Elastomers
Micom Laboratories offers ASTM D624 testing to assess the tear resistance of elastomers and rubber materials. This essential test measures a material’s ability to resist stress, tear initiation, and propagation, ensuring durability and reliability.
About ASTM D624 Testing
The ASTM D624 test evaluates the tear strength of rubber and thermoplastic elastomers, providing key insights into their performance under stress. It measures the force needed to initiate and propagate a tear, helping clients select high-performance materials that meet industry standards for safety and effectiveness.
Why is it important?
ASTM D624 testing is crucial in industries like automotive and medical, where material durability and resistance to tear are essential for product reliability and safety. For example, in automotive applications, it ensures tires made from natural rubber can withstand road impacts. In the medical field, it confirms that latex in medical gloves maintains integrity, ensuring safety.
Benefits of ASTM D624 Testing
- Quality control and assurance: ASTM D624 testing helps ensure consistent quality by identifying potential weaknesses in elastomers before they reach the production stage. It serves as a reliable measure for maintaining the desired material properties throughout manufacturing.
- Product development and improvement: By evaluating the tear strength of different formulations, ASTM D624 testing provides valuable data for optimizing materials. It helps improve the durability and performance of products, enabling our clients to refine designs for better outcomes.
- Compliance with industry standards: This test ensures that materials meet essential industry requirements, helping manufacturers comply with safety regulations.
- Performance validation: ASTM D624 testing can confirm a product’s compliance with its stated tear resistance parameters.
What Types of Elastomeric Materials Can Be Evaluated Using ASTM D624?
ASTM D624 can be used to evaluate a wide range of elastomeric materials, including:
- Natural rubber
- Synthetic rubbers (e.g., SBR, NBR, EPDM)
- Thermoplastic elastomers (TPEs)
- Silicone rubbers
- Polyurethane elastomers
- Fluoroelastomers
- Neoprene
- Butyl rubber
ASTM D624 Testing Process
The ASTM D624 procedure evaluates the tear strength of elastomeric materials.
- The process begins with vulcanizing the sample, which is one sheet, 2.3 ± 1.0 mm thick and large enough to allow our technicians to cut five test specimens in the required shape (types C, T, and CP).
- After vulcanization, the sample is transferred to our laboratory. It is important to prevent light exposure to the sample after vulcanization to ensure accurate results.
- Upon arrival at Micom Laboratories Inc., and prior to cutting, samples are conditioned under standard laboratory conditions (23 ± 2°C and 50 ± 5% RH) for 3 to 24 hours, depending on moisture sensitivity. Due to conditioning requirements and the need for testing within 24 hours of cutting, specimens cannot be precut by the client.
- During testing, specimens are mounted in a tensile testing machine, where the test is conducted at a constant crosshead separation speed, as specified by ASTM D624, ensuring reliable results.
In addition to ASTM D624 tear strength testing, Micom Laboratories offers other elastomer testing services, including ASTM D412.

How do I submit samples for ASTM D624 testing at Micom Laboratories?
To submit samples for ASTM D624 testing, we recommend contacting our team first to be guided through the process and ensure that all necessary steps are followed. The client is responsible for vulcanizing the elastomeric material according to the required specifications. However, after vulcanization, the sample must be cut by our experienced technicians to meet the ASTM D624 test standards. It’s also crucial to prevent light exposure to the sample during its transfer to our laboratory, as exposure to light can affect the accuracy of the test results. Upon arrival, the sample will be conditioned under standard laboratory conditions (23 ± 2°C and 50 ± 5% RH) for the necessary time before testing begins. Our team will assist you throughout the entire submission process to ensure proper handling and accurate test outcomes.
