ISO 178: 2010 Plastics - Determination of flexural properties

The International Organization for Standardization (ISO). Fifth edition. 2010-12-15. This fifth edition cancels and replaces the fourth edition (ISO 178:2001), which has been technically revised to harmonize it with ISO 527-2 with respect to the test speeds used for the determination of the flexural modulus and for the determination of other flexural properties. 24p. This International Standard specifies a method for determining the flexural properties of rigid and semi-rigid plastics under defined conditions. A standard test specimen is defined, but parameters are included for alternative specimen sizes for use where appropriate. A range of test speeds is included.
