ISO 178Plastics - Determination of Flexural Properties
ISO 178 is a test method for the determination of flexural properties of rigid and semi-rigid plastics. These properties include flexural modulus and flexural strength. It is used to investigate the flexural behaviour of the test specimens and to determine the flexural strength, flexural modulus and other aspects of the flexural stress/strain relationship under the conditions defined.
This test standard is equivalent to BS EN ISO 178:2019
Before conducting ISO 178, it is important to read the entire specification. Standards can be obtained from appropriate standard authorities.
