Harry,
IEC 61508 doesn't provide any calculation method for any particular component.
The Siemens link I provided leads eventually to a free online SIL calculator.

HI COLLEAGUES:

I'VE BEEN TAKING A GOOD LOOK & THIS LINK IS A GREAT HELPNESS.

http://www.navsea.navy.mil/nswc/card.../handbook.aspx


BUT IT DOESN'T RESPONSE FROM MY TROUBLE.
I'D LIKE FIND AN CLEAR FULL PROCEDURE FOR SIL CALCULATIONS
(NO ONLY THE MTBF).

ALSO I MUST CALCULATE THESE: PFD, SFF, & SIL.

CAN I'VE AN SIL CFSE / CFSP EXPERT OR SIMILAR QUALIFICATION BESIDE ME?.

TANKS FOR THE CURRENT HELPNESS.

AS.

Harry,

I did not imply it. The original poster asked some other questions apart from SIL calculation (which you had taken care of) and I thought the link and links within it can lead him somewhere.
