Q1: Can I use ASHRAE Standard 70-2006 for a new project in 2024? A: No. Building codes reference the "latest adopted edition." Using a 2006 standard for a new permit will result in plan rejection. You need the updated version (70-2020).
Q2: Is there a free PDF of the updated standard from ASHRAE? A: No. ASHRAE is a non-profit but relies on standard sales to fund research. However, you can read the standard for free at a participating ASHRAE Research Library (e.g., Georgia Tech, UIUC, or Texas A&M). No personal download is provided.
Q3: Does OSHA accept the 2006 version? A: OSHA (Occupational Safety and Health Administration) references ASME, not directly ASHRAE 70. However, OSHA’s process safety management (PSM) standard requires using "recognized and generally accepted good engineering practices" (RAGAGEP). In 2024, the 2006 version is no longer considered RAGAGEP. The updated RAGAGEP is 70-2020.
Q4: I bought an "updated" PDF online that says 70-2006 on the cover. Is it legitimate? A: No. An "updated" 2006 standard is a counterfeit. The date signifies a specific edition; it cannot be updated without changing the year. You have likely purchased a scanned draft. Request a refund and report the seller. ashrae standard 702006 pdf updated
