Description / Abstract:

These requirements apply to direct-fed incinerators, including those of the gas and electric ignition types, designed primarily for use in one-and two-family dwellings for the burning of ordinary combustible waste materials and garbage incidental to domestic occupancy and having a firebox or charging compartment of not over 5 cubic feet capacity. 

Incinerators of this type may also be employed in other occupancies including commercial establishments and institutions where the refuse is of a character for which the incinerator is designed and is not excessive in amount. They are not intended for use in spaces in which flammable vapor or gases may be present. 

Incinerators covered by these requirements are the factory-made type not requiring field construction, and are designed for inside use. These requirements do not cover an incinerator that requires the use of a brick or masonry wall, etc., which forms a part of the building structure, or requires masonry work at the site to complete the incineration chamber. 

A product that contains features, characteristics, components, materials, or systems new or different from those in use when the standard was developed, and that involves a risk of fire, electric shock, or injury to persons, shall be evaluated using the appropriate additional component and end-product requirements as determined necessary to maintain the level of safety for the user of the product as originally anticipated by the intent of this standard.
