17、4A 32.8.10 Manuals. The analyzer shall be delivered with operator, maintenance, and illustrated parts manuals. Format and quantity shall be as specified in the contract or order. 3. REGULATORY REQUIREMENTS 3.1 Recycled, recovered, or environmentally preferable materials. Recycled, recovered, or envi
18、ronmentally preferable materials should be used to the maximum extent possible provided that the material meets or exceeds the operational and maintenance requirements, and promotes economically advantageous life cycle costs. The offeror/contractor is encouraged to use recovered materials to the max
19、imum extent practicable, in accordance with paragraph 23.403 of the Federal Acquisition Regulation (FAR). 3.2 Green Procurement Program. Green Procurement Program (GPP) is a mandatory federal acquisition program that focuses on the purchase and use of environmentally preferable products and services
20、. GPP requirements apply to all acquisitions using appropriated funds, including services and new requirements. FAR 23.404(b) applies and states the GPP requires 100% of EPA designated product purchase that are included in the Comprehensive Procurement Guidelines list that contains recovered materia

The products provided shall meet the salient characteristic
22、s of this CID, conform to the producers own drawings, specifications, standards and quality assurance practices, and be the same product offered for sale in the commercial market. The government reserves the right to require proof of such conformance. 4.2 Metric Products. Products manufactured to me
23、tric dimensions will be considered on an equal basis with those manufactured using inch-pound units, provided they fall within the specified tolerances using conversion tables contained in the latest revision of Federal Standard No. 376, and all other requirements of this CID are met. If a product m
24、anufactured to metric dimensions exceeds the tolerances specified in the inch/pound units, a request should be made to the contracting officer to determine if the product is acceptable. 4.3 The contracting officer has the option of accepting or rejecting the product. 5.
