These requirements cover both portable filters and fixed filters intended to be used with a specific fryer or fryers or with any fryer or fryers.

1.2 These requirements cover oil filters used to filter cooking oil used in deep fat fryers usually found in commercial kitchens, restaurants, or other business establishments where food is dispensed. The filters consist of a pump motor to pump oil to and/or from a deep fat fryer and are capable of including an integral oil heater. The requirements are also applicable to filters built into a fryer.

The other portions of the appliance are to be evaluated in accordance with the requirements that normally apply to that type of equipment. However, consideration shall be given to the interaction between the two portions of the appliance; for example, to the possibility that the entire appliance is capable of being exposed to hot cooking oil.
