In everyday and technical usage it describes how much a material or object has been compacted relative to its original size, and it is commonly expressed as a percentage or as a dimensionless ratio. The exact definition can vary by field, which means the term is not always tied to a single, universal formula.
In materials science and engineering, puristusaste is often linked to a uniaxial compression process. A common
In other industries, such as packaging, papermaking, or food processing, puristusaste can describe the degree of
Because Finnish terminology often differs between sectors, puristusaste does not have a single, universal definition. Readers
