This article provides an exhaustive breakdown of the , explaining how to read it, apply it, and avoid costly manufacturing mistakes.
If a part slightly violates an ISO 2768-mh tolerance but its functional utility is completely unimpaired, the component should not be automatically rejected unless the customer explicitly states so in their contractual documentation.
