Louisiana Revised Statutes Tit. 39, § 1655. Maximum practicable competition

A. All specifications shall seek to promote overall economy for the purposes intended and encourage competition in satisfying the needs of the state, and shall not be unduly restrictive. A specification may be drafted which describes a product which is proprietary to one company only when one of the following applies:

B. Except as provided in Paragraph (A)(2) of this Section, whenever such proprietary specifications are used, the specifications shall clearly state that they are used only to denote the quality standard of supplies, services, or major repairs desired and that they do not restrict bidders to the specific brand, make, manufacturer, or specification named; that they are used only to set forth and convey to prospective bidders the general style, type, character, and quality of supplies, services, or major repairs desired; and that equivalent supplies, services, or major repairs will be acceptable.
