N.J. Stat. § 2A:123-22
The penalties provided for a violation of this act shall not apply to any person who establishes a guaranty received in good faith, signed by and containing the name and address of the person by whom the tent or sleeping bag covered by the guaranty was manufactured or from whom it was received, to the effect that reasonable and representative tests made under the rules and regulations in accordance with the procedures prescribed in this act show that the specific type tent or sleeping bag covered by the guaranty when so tested was flame resistant within the meaning of this act; and that he has not, by further processing affected the flammability of the tent or sleeping bag covered by the guaranty which he received. Such guaranty shall either be a separate guaranty specifically designating the tent or sleeping bag guaranteed, in which case it may be on the invoice or other paper relating to such articles, or a continuing guaranty filed with the director or with the Federal Trade Commission applicable to any tent or sleeping bag handled by the guarantor in such form as the director or the Federal Trade Commission, as the case may be, by rules and regulations, may prescribe. It is provided, however, that a person furnishing such a guaranty, except a person relying upon a guaranty received in good faith to furnish a guaranty to the same effect, if he, by further processing, has not affected the flammability of the tent or sleeping bag covered by the guaranty, shall not be relieved thereby from any of the penalties prescribed for the violations of this act.
