IEC PAS 63325:2020提供了在生命周期不同阶段确保和保证功能安全的要求和指南。它将有助于协调风险评估、设计和管理以及运营过程，避免功能安全和安保之间的冲突。 本PAS并不旨在给出一些全新的生命周期，而是基于功能安全生命周期、安全生命周期和其他最先进的工程流程，旨在提供一些典型阶段的需求和建议，以实现功能安全和安全之间的协调。 本PAS的目标是工业自动化控制系统（IACS），包括受控设备（EUC）系统和安全相关系统。

IEC PAS 63325:2020 provides requirements and guidance on the ensurance and assurance of functional safety and security in different stages of the lifecycle. It will help to coordinate risk assessment, design and management and operation processes, avoiding conflicts between functional safety and security.
This PAS does not aim to give some completely new lifecycle, but based on the functional safety lifecycle, security lifecycle and other state of the art engineering processes, it aims to provide requirements and suggestions in some typical stages to achieve coordination between functional safety and security.
The objective of this PAS is Industry Automation Control System (IACS), including Equipment Under Control (EUC) system and safety-related system.
