Functional safety support for safety-critical systems.
ExConform has extensive experience in functional safety, the application of both IEC 61508 and IEC 61511, and associated machinery safety standards such as ISO 13849-1. From hazard identification and SIL or PL determination, to Safety Requirement Specifications, verification and validation, ExConform can assist with any phase of the functional safety lifecycle.
Functional Safety Lifecycle Support
Standards-based support
Application of IEC 61508, IEC 61511 and ISO 13849-1 for process and machinery safety systems.
Lifecycle evidence
Support from hazard identification through to SRS, verification, validation and assessment readiness.
Competent assessment
Engineers with practical functional safety experience and exida Functional Safety Practitioner certification.
Assessment from sensor to final element.
Functional safety depends on the complete safety function, not just one component. ExConform reviews the sensor, logic solver and final element arrangement together with the assumptions used for diagnostics, proof testing, systematic capability and failure behaviour.
We apply industry-recognised calculation methods for both SIL assessment and verification, helping clients demonstrate whether the implemented safety function meets the required risk reduction.
Assistance with any phase of the functional safety lifecycle.
From early hazard review to final Functional Safety Assessment, ExConform provides practical support where safety evidence must be clear, consistent and technically justified.
Hazard identification and SIL / PL determination.
Identification of hazardous events and determination of the required Safety Integrity Level or Performance Level.
Safety Requirement Specification.
Development or review of Safety Requirement Specifications with clear functional, integrity and validation criteria.
Verification, validation and FSA support.
Review of calculations, evidence and validation records to support Functional Safety Assessment readiness.
Functional Safety Assessments for process and machinery applications.
The following technical diagrams are used as diagrams, not decorative backgrounds, so the content remains clear and readable.
Determine the required risk reduction.
ExConform supports SIL determination and Performance Level determination using structured, recognised approaches that connect hazard severity, exposure, avoidance and probability to the required integrity target.
Review the full safety function chain.
We assess the complete safety function architecture and the assumptions behind it, including sensor, logic solver and actuator performance, diagnostics, proof testing and final validation evidence.
Apply IEC 61508, IEC 61511 and ISO 13849-1 correctly.
ExConform supports the application of functional safety standards for both process safety and machinery safety applications, including novel systems where standard templates may not be sufficient.
Experience with IEC 61508, IEC 61511 and ISO 13849-1.
ExConform has completed projects on many novel applications and systems, and has assisted clients through important Functional Safety Assessments.
Because proof of competence is important to meet both standards and client requirements, our engineers are exida Functional Safety Practitioner certified.
Focused functional safety support.
ExConform can assist with any phase of the functional safety lifecycle, from first hazard review to Functional Safety Assessment close-out.
