ISO 178 is a test method for the determination of flexural properties of It rigid and semi - It rigid plastics. These properties include flexural modulus and flexural strength. It is 2 the 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 the conditions defined.
This test standard is equivalent to BS EN ISO 178:2019
Before conducting the ISO 178, it is important to read the - specification. The Standards can be obtained from the appropriate standard authorities.
