Docs for SIL Certification on Type A components

(OP)
I'm working on a documentation process to guide engineers through functional safety management IAW IEC 61508. We currently design and manufacture only Type A components (mostly final element components like valves, pneumatic actuators, etc). Parts of the standard such as software requirements just flat out don't apply, but others are not quite so clear cut. It seems to me that things like the SRS and all the elements that go into it (hazard and risk analysis, overall safety req, safety req allocation) probably aren't needed for simple mechanical devices, and are more appropriate for systems design. How would one specify a safety requirements allocation in the design phase of a single Type A component?

Am I wrong about that? If the SRS really is needed for Type A components, does anyone know where I can find some examples of a Type A safety life-cycle and the associated documentation?
