The guidelines to the regulations often refer to recognized standards as a way to fulfil the functional requirements in the regulations.
International standards, like ISO, IEC and EN standards, will normally not be available in full-text on the Internet. These standards can be ordered from the national standardisation organization. This will also apply to most national standards, like API-standards.
On the other hand, some petroleum-related standards, e.g. those issued by NORSOK, DnV and OLF, are available in full-text on the Internet. Below you will find links to websites where you can order or download standards that are referred to in the guidelines.
