Definition:
A Product Safety Manual is a document provided by a manufacturer that defines the functional safety capabilities, proper use conditions, limitations, proof test procedures, and installation requirements for a device intended for use in a SIS.
It often will not be called this formal name. It may simply be the “manual” or “functional safety manual” or just be a functional safety section.
Key Points:
- Required for devices certified under IEC 61508.
- Specifies how to properly install, operate, and maintain the device to achieve the advertised SIL rating.
- Often includes proof test intervals, diagnostic coverage, safe failure fraction, types of testing, and environmental ratings.

Example:
A safety-rated solenoid valve’s Product Safety Manual states that it must be proof tested every 12 months and installed in a clean, dry environment to maintain its SIL 2 capability.
