SIL Certification

SIL Certification

What is SIL certification?

SIL certification can be provided to all the electrical, electronic and programmable electronic products or any components which are intended to be used into one or more safety functions as per the requirements of IEC 61508.

Each SIL level represents the extent of risk reduction required to maintain acceptable rate of failure. SIL certification covers assessment of industrial products which are intended to be used in any safety function with respect to the relevant parts and requirements of the IEC 61508 series standard for a safety integrity level. This is generally achieved by an assessment of the product and the processes by a third party assessor.


Why to consider SIL Certification for your products?

SIL certification for your product can considered for following reasons:

  • SIL certification is mandatory contractual requirement in most of the tenders of PSU’s in India as well as in international export for both mechanical products / systems and for electrical / electronic /programmable electronic products.
  • Compliance to the requirements for SIL certification also streamlines your product development and quality management system processes.
  • SIL certification provides recognition, increases brand value of your product and opens up new avenues earlier rendered inaccessible.
  • SIL certificate most importantly underlines reliability of your product.


How TUV India can help?

TUV India helps manufacturers to fulfil all necessary requirements as per standard and to establish the reliability of their products. TUV India can support for the certification of safety-relevant products in the area of electrical/ electronic/programmable electronic systems (E/E/PE systems), offering following services.

  • Performance of fault tree analyses (FTA) and failure mode and effect analyses (FMEA/ FMEDA).
  • Determination of safety-related parameters within the framework of IEC 61508, IEC 61511, IEC/EN 62061, EN ISO 13849; such as PFDavg, PFH, HFT, CCF, SFF, λSU, λDU, λDD, λSD etc.
  • Verification of functional safety in accordance with IEC 61508, IEC 61511, IEC/EN 62061, ISO 13849,etc.
  • Assessment/development of documentation for management of functional safety and design & development life cycle.


Standards include:

  • IEC 61508: Functional Safety of Electrical / Electronic / programmable electronic safety related system
  • IEC 61511: Functional safety - Safety instrumented systems for the process industry sector
  • IEC 62061: Safety of machinery: Functional safety of electrical, electronic and programmable electronic control systems
  • EN ISO 13849-1-2015 : Safety of machinery — Safety-related parts of control systems — Part 1: General principles for design
  • EN ISO 13849-2-2012 :  Safety-related parts of control systems — Part 2: Validation

Who all can avail SIL Certification?

The SIL certification services are directed towards manufacturers & system integrators of E/E/PE safety related systems which are intended to be used as a part of safety system.

TUV India can help manufacturers or integrators with SIL certification of High Integrity Protection System (HIPS), Burner Management System (BMS), globe valves, butterfly valves, ball valves, plug valves, pneumatic, hydraulic and electric actuators, transmitters (level, pressure, temperature, flow), process connections like remote seal, manifolds etc., intrinsic safety barriers, logic solvers, PLC, solenoid valves, electro-mechanical relays, pneumatic accessories like pilot valves, quick exhaust valves, volume booster, partial stroke devices, microprocessor, firmware etc.
