ISO Guidelines

Definition

ISO Guidelines refer to the standards set by the International Organization for Standardization (ISO) that provide a framework for the evaluation and classification of material properties, particularly in relation to yield criteria and failure theories. These guidelines help ensure consistency and reliability in assessing the performance and safety of materials under different loading conditions, which is crucial in engineering design and analysis.

5 Must Know Facts For Your Next Test
