International Organization for Standardization

(ISO) is an international standard-setting body that develops and publishes international standards for a wide range of industries, including the mechanical engineering industry. ISO standards provide a common set of guidelines and requirements that help to ensure the quality, safety, and reliability of products and services.

In the context of mechanical bench testing, ISO standards provide a set of standardized test methods and procedures that are used to evaluate the performance and reliability of mechanical components and systems. These standards for cushion cover a wide range of test types, including immersion, envelopment, contact area, and horizontal force to name a few. There are several key benefits to using standardized mechanical bench testing:

  • 1 Consistency: Standardized tests provide a consistent and repeatable method for evaluating the performance of a product. This ensures that different products can be compared on an equal footing and allows for accurate and reliable quality control.

  • 2 Objectivity: Standardized tests are objective, as they are based on predetermined criteria and procedures. This helps to eliminate subjectivity and bias in testing, ensuring that the results accurately reflect the performance of the product.

  • 3 Validity: Standardized tests are designed to accurately reflect the conditions and requirements that a product is likely to encounter in the real world. This helps to ensure that the results of the testing are relevant and meaningful and that the product is fit for its intended use.

ISO standards are developed by technical committees made up of experts from around the world. These committees work together to develop standards that are based on the latest research and best practices in their respective fields. Once a standard has been developed, it is published by ISO and made available for use by industry, government, and other organizations.

The use of ISO standards in mechanical bench testing helps to ensure that test results are consistent and reliable, and that products are fit for their intended use. By following ISO standards, manufacturers and testing laboratories can be confident that they are using a proven, reliable method for evaluating the performance of their products.

Anthros is committed to this level of testing to ensure that we bring the best possible product to the market. We partnered with the University of Pittsburgh School of Health Sciences and Rehabilitation who are one of the leading wheelchair cushion testing labs in the country. We had them test the Anthros seat cushion on three measures that have been shown to relate to comfort- shear, pressure, and contact area. The results speak for themselves!
