Option 3: The "Free PDF" Warning

You will find websites offering a free ASHRAE Standard 70-2006 pdf download. Be extremely wary. These are typically:

Scanned Chinese or Indian "National Adoptions" (which have modified text).
Corrupted files containing malware.
Incomplete drafts missing critical tables (e.g., Table 4 - Tolerances on Instrumentation).

Legal Note: ASHRAE holds copyright. Using a pirated PDF for professional engineering certification exposes you to liability if your calculations are based on a bootlegged, corrupted copy.
