ISO 844: Compressive Testing of Rigid Cellular Plastics

ISO 844: Compressive Testing of Rigid Cellular Plastics

ISO 844 outlines the procedure for determining the compressive properties of rigid cellular plastics, a critical step in evaluating foam materials under compressive loads. This video provides a clear overview of the standard and its key requirements.

Test specimens must meet strict dimensional criteria, with the preferred shape being a right prism with 100 mm sides for consistent alignment.

During testing, the specimen is placed between two rigid platens. Proper alignment is essential to avoid uneven stress distribution. Strain can be measured using the crosshead or an extensometer, such as LVDT compression deflectometers or optical systems like the AVE3 Advanced Video Extensometer.

ISO 844 specifies these outputs:
• Compressive strength
• Relative deformation at compressive strength
• Compressive stress at 10% deformation
• Compressive modulus of elasticity

These results help engineers assess material performance for structural, cushioning, and energy-absorbing applications. Always review the full ISO 844 standard before testing to ensure compliance.

The Hidden Variables in Your Test Results

The Hidden Variables in Your Test Results

Watch this webinar to learn how the AVE3’s advanced engineering helps you take control of your testing environment and ensures consistent, high-accuracy results wherever you test.

In materials testing, precision and accuracy are everything — yet many labs unknowingly compromise their results due to one commonly overlooked factor: the environment they test in. Fluctuating lighting, thermal disturbances, and other external factors can quietly degrade data quality, leading to inconsistent and inaccurate results. These influences often go unnoticed, but their impact can be significant, especially in high-stakes applications where accuracy is critical.

The newly released Instron® AVE3, the latest generation of its advanced video extensometer, was purpose-built to address this challenge. Designed to perform reliably in virtually any lab environment — from harsh industrial settings to tightly controlled research labs — the AVE3 ensures consistent, high-accuracy strain measurement regardless of external conditions.

What you’ll learn:

  • Why non-contacting extensometers are the preferred choice for countless applications
  • How environmental conditions can impact strain measurement accuracy
  • The engineering innovations behind the AVE3’s robust and adaptive performance
  • How to optimize device settings for maximum precision
