Functional Safety Assessment is a third-party assessment and verification that evaluates and confirms the Safety Integrity Level or Performance Level of a safety-related system. It mainly involves FSM for development process for a safety-related system, evaluation of hardware reliability calculation and software, environmental testing, EMC electromagnetic compatibility testing, etc.
In 2000 with the issue of IEC61508.1-7 "Electrical/electronic/programmable electronic safety related system of functional safety" standard, functional safety as an independent safety discipline has entered into the practical application stage. Subsequently, functional safety standards for various application fields were developed. SIL assessment provides good confidence for owners to purchase and enterprises to promote their products from a third party perspective.
In the field of rail transit, we conduct SIL assessment according to EN50126/EN50128/EN50129 and other CENELEC or their equivalent standards for signalling, vehicle and other safety related core systems or product development process. The SIL level in this field is usually SIL1 to SIL4.
When damage happened, minimize the legal responsibility and compensation
TÜV NORD's product functional safety assessment team has many years of project experience in both domestic and overseas, covering various types of equipment for metro and new rail transit systems. In recent years, TÜV NORD has implemented functional safety assessment for several safety computer platforms, braking, traction, TCMS, LCU, DCU, on-board and trackside signaling products.
TÜV NORD has dual accreditation with CNAS and DakkS, and can provide our customers with one-stop “one assessment and dual certificate" service.
