PSTD-007

Pack: F_OVERLAY Severity: major

Pipe thread callouts must explicitly state ISO 228-1 for G-threads

Rule Card

Field	Value
Pack	F_OVERLAY — Industry Overlay and Compliance
Title	Pipe thread callouts must explicitly state ISO 228-1 for G-threads
Severity	major
Check logic	Deterministic
Applies to	Compliance overlay
Inputs required	thread_callouts
Fix template	Revise pipe thread notes to include 'ISO 228-1' and the proper designation (e.g., 'G 1/2'). Specify sealing method elsewhere if joint must be pressure tight.

Short Description

Ensures pipe threads intended as ISO 228-1 are called out as ISO 228-1 to avoid confusion with pressure-tight thread standards.

When It Applies

This rule runs only when an overlay activates F_OVERLAY. It targets Compliance overlay.
