Which standard applies to testing listed hood assemblies (excluding ultraviolet hoods)?

Explanation:
Testing listed kitchen hood assemblies is governed by UL 710, which covers Ventilating Hoods and Systems and sets the requirements and test methods for kitchen hoods and their interfaces with exhaust and fire-suppression components. This is why UL 710 or equivalent is the correct standard. The other standards address different things: UL 555 deals with fire dampers in ductwork, UL 1479 focuses on general fire-resistance testing for materials and joints, and ISO 9001 is a quality-management standard with no specific performance testing for hood assemblies.
