Threads used in joints and fittings shall conform to which standards?

Explanation:
Threads used in joints and fittings must match established pipe-thread standards so that connections seal reliably. NFPA 2001 specifies that these threads conform to either ANSI B1.20.1, which covers general pipe threads, or ISO 7-1, which defines dimensions for pipe threads used to create pressure-tight joints. Allowing either standard ensures compatibility with equipment from different regions and manufacturers, promoting a leak-tight seal in clean-agent systems. Relying on a single standard would limit compatibility, and a standard like ASME B1.3 is not the relevant pipe-thread standard for this application.
