In addition to the definitions set forth in section 3 of the act (15 U.S.C. 2052) and in § 1205.3 of the standard, the following definitions shall apply to this subpart B of part 1205:

(a) Manufacturer means any person or firm that manufactures or imports power lawn mowers subject to this standard, and includes those that assemble power lawn mowers from parts manufactured by other firms.

(b) Manufactured means the earliest point at which the mower is in the form in which it will be sold or offered for sale to the consumer or is in the form in which it will be shipped to a distributor or retailer. In these forms, a “manufactured” mower may still require partial assembly by the consumer or the lawn mower dealer.

(c) Private labeler means an owner of a brand or trademark which is used on a power lawn mower subject to the standard and which is not the brand or trademark of the manufacturer of the mower, provided the owner of the brand or trademark has caused or authorized the mower to be so labeled and the brand or trademark of the manufacturer of such mower does not appear on the label.

(d) Production lot means a quantity of mowers from which certain mowers are selected for testing prior to certifying the lot. All mowers in a lot must be essentially identical in those design, construction, and material features which relate to the ability of a mower to comply with the standard.

(e) Reasonable testing program means any test or series of tests which are identical or equivalent to, or more stringent than, the tests defined in the standard and which are performed on one or more mowers of the production lot for the purpose of determining whether there is reasonable assurance that the mowers in that lot comply with the requirements of the standard.
