1.1 These requirements cover Type I commercial kitchen exhaust hoods intended for placement over commercial cooking equipment. Exhaust hoods with and without exhaust dampers are covered by these requirements.
1.2 Exhaust hoods with and without exhaust fire actuated fire dampers are covered by these requirements
1.3 Exhaust hoods are evaluated relative to minimum exhaust air flow required and maximum supply air flow allowed for capture and containment of cooking effluents under laboratory conditions.
1.4 Exhaust hoods may incorporate non-continuous welded joints, seams, and penetrations when evaluated by these requirements.
1.5 Exhaust hoods with fire actuated fire exhaust dampers are intended to have the exhaust fire actuated dampers automatically close to prevent exhaust duct gas temperatures from exceeding 375°F (191°C).
1.6 All exhaust hoods are intended for use with fire extinguishing system units.
1.7 These requirements cover exhaust hoods provided with manually or automatically operated cleaning or washing systems. These requirements do not cover the fire extinguishing aspects of such systems.
1.8 These requirements do not cover evaluation of Ultra Violet (UV) systems for use in commercial kitchen exhaust systems . The Outline for Ultraviolet Radiation Systems for Use in the Ventilation Control of Commercial Cooking Operations, UL 710C, covers these products.
1.9 These requirements do not cover evaluation of Electrostatic Precipitators (ESP’s) for use in commercial kitchen ventilation. Electrostatic Precipitators (ESP’s) are covered under the Standard for Electrostatic Air Cleaners, UL 867.
1.10 These requirements do not cover evaluation of commercial electric cooking appliances provided with integral recirculating systems (previously referred to as ductless hoods) and nonintegral recirculating systems, both of which are intended for installation in commercial establishments for the preparation of food. The Standard for Recirculating Systems, UL 71 OB, covers these products.
1.11 Exhaust hoods covered by these requirements are intended for installation in accordance with the following:
a) The Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations,
NFPA96;
b) The National Electrical Code, NFPA 70; and/or
c) Other codes such as the International Mechanical Code (IMC) and the Uniform Mechanical
Code (UMC).
1.12 These requirements cover products rated 600 volts or less.
1.13 These requirements do not cover evaluation of the exhaust hoods with respect to their grease extraction efficiency.
2 Units of Measurement 2.1 If a value for measurement is fllowed by a value in other units in parentheses, the first stated value is the requirement. 3 Components 3.1 Except as indicated in 3.2, a component of a product covered by this standard shall comply with the requirements for that component. See Appendix A of standards covering components used in the products covered by this standard. 3.2 A component is not required to comply with a requirement specifed in its specifc standard when it: a) Involves a feature or characteristic not required in the application of the component in the product covered by this standard; or b) Is superseded by a requirement in this standard. 3.3 A component shall be used in accordance with its recognized rating established for the intended conditions of use. 3.4 Specific components are recognized as being incomplete in construction features or restricted in performance capabilities. Such components are intended for use only under limited conditions, such as certain temperatures not exceeding specified limits, and shall be used only under those specific conditions for which they have been recognized. 4 Undated References 4.1 Any undated reference to a code or standard appearing in the requirements of this standard shall be interpreted as referring to the latest edition of that code or standard. 5 Glossary 5.1 For the purpose of this Standard the fllowing definitions apply. 5.2 CIRCUIT, HIGH-VOLTAGE – A circuit having characteristics in excess of those of a low-voltage circuit.
