Reference definitions for paint-cell terminology used in feasibility reviews, equipment selection, process setup, and production planning.
Best used for
Best used to create shared vocabulary across engineering, purchasing, operations, integrators, and external suppliers.
Use with caution
Definitions do not replace equipment datasheets, coating TDS/SDS documents, or site-specific compliance review.
Evidence basis
Compiled from TD engineering terminology, project scoping language, and equipment-integration workflows.
ATEX certification indicates equipment is approved for use in potentially explosive atmospheres, required for paint cells using flammable solvents. Certification covers electrical and mechanical equipment in hazardous zones.
Why it matters in paint cells
- •Mandatory for equipment in hazardous zones
- •Affects equipment selection and cost
- •Zone classification determines requirements
Zone classifications
- •Zone 0: Explosive atmosphere present continuously (rare in paint cells)
- •Zone 1: Explosive atmosphere likely during normal operation (spray zone)
- •Zone 2: Explosive atmosphere unlikely, only under fault conditions
- •Zone classification determines required equipment protection level
What to watch for
- •Zone classification and equipment ratings
- •Installation and maintenance requirements
- •Documentation and compliance verification
