It is crucial to understand that standards are copyrighted documents and a major source of revenue for standards bodies like the BSI. The only way to ensure you have the complete, correct, and legally compliant version is to purchase it directly from an authorized distributor. Using an unofficial or free copy is risky; it may be an outdated draft, contain errors, or be missing critical information.
