ISO 604Plastics -- Determination of compressive properties
ISO 604 specifies a method for determining the compressive properties of plastics in the form of standard test specimens when tested under defined conditions of pretreatment, temperature, humidity and testing machine speed. The compressive properties determined by this method include compressive yield stress, compressive strength, offset yield stress, percentage compressive strain at rupture and compressive stress at specified compressive strain.
This test standard is equivalent to BS EN ISO 604:2003.
Before conducting ISO 604, it is important to read the entire specification. Standards can be obtained from appropriate standard authorities.
