The ISO 37 or ISO 037 test standard deals with the determination of the tensile strength and elongation of rubber and elastomers. The standard ensures that the mechanical properties of the two materials are tested under standardised conditions so that the results are comparable. The results ensure that products made from these materials meet the required specifications and quality standards.

The main part of ISO 37 focuses on the tensile test to measure the tensile strength and elongation of materials. The test is carried out on a tensile testing machine, which stretches the sample in a controlled manner and simultaneously measures the forces that occur, which are analysed by the testing software. The results include the following characteristic values:

• Tensile and tear strength
• Elongation at break and elongation at break
• Yield strength
• Stress at specified elongation values

This data is crucial for assessing the performance and suitability of the material for specific applications.

Typical areas of application

• Automotive industry: Testing of seals, hoses and other elastomer components.
• Medical devices: Ensuring the durability and reliability of rubber components in medical applications.
• Construction industry: Evaluating the suitability of sealing materials and other rubber-based products.

Test system for testing in accordance with ISO 37

The inspekt table testing machines from Hegewald & Peschke are ideally suited for carrying out tensile tests in accordance with ISO 37. With the ability to precisely stretch the test specimens and measure the forces that occur, they fulfil all the requirements of the test standard. The equipment with extensometers, such as the L1100 long distance extensometer, enables precise determination of the elongation, which is particularly important for determining the elongation at break and the moduli at different elongations.

Specifications:

• Force range: The inspekt table testing machines are available in various models covering force ranges from 5 kN to 250 kN, with models in the lower force range being particularly suitable for testing rubber and elastomers.
• Testing speed: These machines offer a variable testing speed that can be adapted to the specific requirements of ISO 37.
• Modular design: The machines have a modular design and can be equipped with various accessories and extensions as required.

Further features:

• Precision and accuracy: inspekt table testing machines are known for their high precision in force and displacement measurements, making them ideal for ISO 37 requirements.
• Versatility: These machines can be used for a variety of materials and test methods, including rubber and elastomers.
• Expandable functionality: With a wide range of accessories, such as various fixtures and extensometers, the machines can be customised to meet specific testing requirements.
• User-friendly software: The LabMaster testing software enables easy control of the machine and offers comprehensive functions for data evaluation and reporting.
• Benutzerfreundliche Software: Die Prüfsoftware LabMaster ermöglicht eine einfache Steuerung der Maschine und bietet umfassende Funktionen zur Datenauswertung und Berichterstellung.
