Standards & Industries
Your industry determines which standards apply. Pick an industry to see its standards, or browse the full map. Document types like HARA and FMEA are listed separately below because they are work products, not standards.
Standards directory

Automotive functional safety standard defining ASIL levels and the automotive safety lifecycle.
Autonomous Machine Safety - Earth-Moving
Safety requirements for autonomous and semi-autonomous earth-moving and mining machines.
Earth-Moving Machinery - Functional Safety
Functional safety framework for earth-moving machinery control systems, defining MPL levels.
Process Industry Safety Instrumented Systems
Application of IEC 61508 to safety instrumented systems in the process industries.
Industrial Automation and Control Systems Security
The industrial cybersecurity standard family: security levels, zones and conduits, and secure development for control systems. Security and safety programs increasingly certify together.
Road Vehicles - Cybersecurity Engineering
Automotive cybersecurity lifecycle: threat analysis and risk assessment (TARA), security requirements, and post-production monitoring. The security companion to ISO 26262.
Road Vehicles - Safety and Artificial Intelligence
Guidance for assuring AI-based functions in road vehicles: data quality, model behavior bounds, and AI-specific verification evidence, extending ISO 26262 and ISO 21448.
Medical Device Software Life Cycle Processes
IEC 62304 defines the software lifecycle expected for medical device software and software embedded in medical devices. CSA treats it as a safety-critical software route when product teams need requirements, risk controls, verification evidence, and release discipline that can survive regulatory review.
Document types (not standards)
HARA, FMEA, and safety cases are work products produced under these standards - not standards themselves. Open a document type for its purpose, typical contents, and related work products.
HARA
Hazard Analysis and Risk Assessment
Produced: Concept phase
Systematic identification of hazards and assessment of risk to derive safety goals and integrity targets. A HARA is a document produced by a process, not a standard.
Safety Plan
Functional Safety Plan
Produced: Program start
Defines the safety lifecycle activities, roles, independence requirements, and evidence plan for a program.
FMEA
Failure Modes and Effects Analysis
Produced: Design phase
Bottom-up analysis of component failure modes and their system-level effects.
FMEDA
Failure Modes, Effects and Diagnostic Analysis
Produced: Hardware design
Quantitative extension of FMEA adding failure rates and diagnostic coverage to compute hardware safety metrics.
FTA
Fault Tree Analysis
Produced: Design and verification
Top-down deductive analysis tracing an undesired event to combinations of contributing faults.
Safety Requirements Specification
Safety Requirements Specification
Produced: Requirements phase
The complete, verifiable statement of safety functions, integrity levels, and constraints.
V&V Plan
Verification and Validation Plan
Produced: Before integration
Defines how each safety requirement will be verified and how the system will be validated against intended use.
Safety Case
Safety Case
Produced: Certification / release
The structured argument, supported by evidence, that a system is acceptably safe for a given application in a given environment.
