Submittals for each manufactured item shall be current manufacturer's descriptive literature of cataloged products, equipment drawings, diagrams, performance and characteristic curves, and catalog cuts. When data that describe more than one type or size of equipment or material are submitted, the submittal shall be clearly marked to indicate which type or size of equipment or material the Contractor is proposing to supply.

1.3.3 Publication Compliance

Where equipment or materials are specified to conform to industry and technical society publications of organizations such as CEI, IEC, and UNI, shall have CEE certifications, and proof of such compliance shall be submitted. The label or listing by the specified organization will be acceptable evidence of compliance. In lieu of the label or listing, submit a certificate from an approved independent testing organization adequately equipped and competent to perform such services, and approved by the Contracting Officer’s Technical Representative, stating that the item has been tested in accordance with the specified organization's test methods and that the item conforms to the specified organization's applicable publication.

1.3.4 Certified Test Reports

1.3.5 Certificate of Compliance

Submit manufacturer's certifications as required on products, materials, finish, and equipment indicated in the technical sections. Certifications shall be documents prepared specifically for this contract. Preprinted certifications and copies of previously submitted documents will not be

Section 16050 3 acceptable. The manufacturer's certifications shall name the appropriate products, equipment, or materials and the publication specified as controlling the quality of that item. Certification shall not contain statements to imply that the item does not meet requirements specified, such as "as good as," "achieve the same end use and results as materials formulated in accordance with the referenced publications," or "equal or exceed the service and performance of the specified material."

Certifications shall simply state that the item conforms to the requirements specified. Certificates shall be printed on the manufacturer's letterhead and shall be signed by the manufacturer's official authorized to sign certificates of compliance.
