Simultaneous creep tests on metals

This space-saving creep testing solution allows you to test the creep strength of three metal specimens simultaneously up to +1,200 °C in accordance with ISO 204 and ASTM E139 and is ideal for small testing labs with limited space.

Accessories for creep testing

Heating systems

For creep testing systems there is a wide range of heating systems available, which meet the different standards and customer requirements. Get an overview of the possible alternatives.

3-zone furnace up to +1,200°C
3-zone furnace up to +1,500°C
Short furnace up to +1,200°C
Induction heating system up to 1,200°C
Chamber for vacuum and inert gas environment up to +2,000°C
Temperature chamber up to +250°C

Universal 3-zone furnace controller

For creep testing in an extended temperature range, exact temperature control along the specimen throughout the full duration of the test is essential. The temperature controller developed by ZwickRoell and proven for many years, ensures precise, reproducible, and user-independent temperature control of the specimen during every test. The universal 3-zone furnace controller meets all requirements of the current international test standards such as DIN EN ISO 204, DIN EN ISO 6892-2, ASTM E139, ASTM E21.

Specimen temperature measurement with attached thermocouples

Specimen temperature measuring device

For temperature measurement directly on the specimen the ZwickRoell creep testing systems are equipped with a specimen temperature measuring device.

For creep tests normally up to three thermocouples are used, which are connected to the specimen. With the connection of the thermocouples it is ensured that the specimen temperature is measured on the correct location throughout the duration of the test.

Load strings for creep tests up to 1,500°C

Load string for tests up to +1,500°C

For creep testing in high temperatures, ZwickRoell offers high-temperature load strings up to +1,500°C.

The load string consists of:

Pull-rod mounting
Pull rod
Specimen adapter

The high-temperature load string transmits the force from the high-temperature specimen adapters in the furnace to the pull-rod mountings outside the furnace. For creep tests in extended temperature ranges the pull-rods and specimen adapters therefore have to hold up to special thermal loads. Metallic high-temperature pull-rods are ideal for use up to +1,200°C and ceramic high-temperature pull-rods up to +1,500°C.

Non-contact extensometers

The differentiating advantage of extensometers featuring non-contact measurement is that they can be used right up to break without risk of damage, even with specimens that are critical in this respect. Sensitive specimen remain unaffected and with the laserXtens the need for time-consuming specimen marks is eliminated. Especially in an extended temperature range, non-contact extensometers provide a defining advantage over contact extensometers, since the access to furnace and temperature chambers can be sealed with view windows. Additional features such as another measurement axis for transverse strain and determination of strain distribution are further unique qualities that only a non-contact measuring system can offer.

With the wide selection of non-contact extensometers, our engineers are happy to help you find the right product for your application.

Contact extensometers

Contact extensometers for creep testing are available for tensile as well as compression and flexure tests. In addition to different accuracy classes and measurement ranges, extensometers for extended temperature ranges are also available. A distinction is made between side- and axial-attaching extensometers, which are suitable for special test types such as crack propagation testing. Depending on the specimen shape, different sensor arms are used. Well designed swivel units allow for easy operation and fast test-readiness.

With the wide selection, our engineers are happy to help you find the perfect contact extensometer for your application.

Overview of heating systems for creep testing

3-zone furnace up to +1,200°C
