PSTD-009

Pack: F_OVERLAY Severity: major

Food-contact designs must not include enclosed/trapped volumes in product/splash zones

Rule Card

Field Value
Pack F_OVERLAY — Industry Overlay and Compliance
Title Food-contact designs must not include enclosed/trapped volumes in product/splash zones
Severity major
Check logic Hybrid
Applies to Compliance overlay
Inputs required geometry_features
Fix template Eliminate enclosed cavities in hygienic zones (open, vent, drain, or redesign); if a cavity is necessary, document cleaning/inspection access and validation.

Short Description

Flags enclosed cavities or trapped volumes in product-contact or splash zones that are difficult to clean, supporting EN 1672-2 hygienic/cleanability intent.

When It Applies

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