IEC 61508 is a key functional safety standard applicable across industries, especially where specific safety standards are absent.
It provides guidelines for the lifecycle management of electrical, electronic, and programmable systems, emphasizing a systematic approach to risk reduction adaptable to various sectors. It also introduces Safety Integrity Levels (SILs) to quantify failure risk.
Our Services
Functional Safety Management
-
Develop detailed safety plans, harmonize processes, and document all phases from concept to decommissioning to maintain the integrity of safety-related systems.
SIL Assignment
-
Perform Hazard Analysis with applicable risk management techniques to determine SIL.
-
Allocate SIL to hardware (and software) for E/E/PE systems
Hardware Analysis
-
Conduct FMEDA to calculate SFF (Safe Failure Fraction) and PFH/PFD of the safety functions.
Software Tools
-
Advise on the selection of appropriate software tools necessary for managing the product lifecycle, drawing on our expertise with industry-specific tools
Testing and Validation
-
Support in creation of system hardware and software test plans, including fault insertion test.
-
Ensure that all the clauses from IEC 61508 are followed and documented.
Assessment & Certification
-
Conduct third-party safety assessments and audits and collaborate with certification agencies such as TUV.
Why QTSI?
-
Successful SIL2 certification of safe operating envelope applied to a naval system.
-
FMEDA analysis of E/E/PE system under high demand mode consisting of combination of architectures (1oo2, 1oo3 etc.).
-
FMECA on the hardware components of E/E/PE system, which comprised over 2000 components.
-
Support OEMs to achieve certification via external certification agencies such as TUV, UL
