This is pretty normal? I work for a company that develops lab machines and we have a bunch of designs we have to follow:

ISO 12100 (Safety of Machinery): Sets general, fundamental principles for design, risk assessment, and reduction (Type A standard).

ISO 13849-1 (Safety-Related Parts of Control Systems): Defines performance levels and categories for safety-related components (Type B standard).

ISO 13850 Safety of machinery – Emergency stop function – Principles for design

And that's just some of them.
