Compression Testing
Compression Testing
Compression testing is a way of determining how something will react when it is squashed, or when a force is applied to it in compression. It is performed to:
- Assess the strength of components e.g. automotive and aeronautical control switches, compression springs, bellows, keypads, package seals, PET containers, PVC / ABS pipes, solenoids etc
- Characterise the compressive properties of materials e.g. foam, metal, PET and other plastics and rubber
- Assess the performance of products e.g. the expression force of a syringe or the load-displacement characteristics of a tennis ball
Types of Compression Tests include:
Benefits of Compression Testing
These include:
- Ensuring the integrity and safety of products
- Ensuring components, materials and products are fit-for-purpose
- Reducing material costs and achieving lean manufacturing goals
- Compliance with industry standards
Standards
There are many standards for compression testing, developed by organisations such as ASTM, BS, DIN, ISO and MIL. They include:
- ASTM C864-05, ASTM D575-91, D905-98, D1710-02, D6147-97, D6713-01, ASTM E9-89a, ASTM F628-06
