Description

Based on the experiences of nine partners from fields as diverse as oil and gas production, transportation, aerospace, nuclear power, and defense, this work presents an in-depth examination of the issues involved in assuring consistent functionality of safety software through rigorous testing. This handbook presents clear guidelines on leading practices of testing safety-related software, including the latest IEEE and IEC standards.
