Section 508 is a standard to ensure your website is accessible to people with disabilities who rely on assistant technologies such as screen readers or other devices.
While it's implementation is for the USA audience it shouldn't be ignored outside the USA just because it isn't mandatory. It is a very valid best practice that should be implemented by everyone who can. I'm not subject to it but I have it implemented in all sites because it's the right thing to do. It can get frustrating at times trying to code things to pass the test but I'll bet it's equally as frustrating for people with disabilities who are unable to access your information and can't because our code breaks there devices -- I don't mean literally but breaks as in exits due to being unable to parse the page.
