REQUIREMENTS DOCUMENT

Title: Environmental Chamber Requesting Lab: Engineering Lab; Materials and Structural Systems Division

I. BACKGROUND INFORMATION

The National Institute of Standards and Technology (NIST) Engineering Laboratory (EL) Materials and Structural Systems Division (MSSD) studies the durability and service life of infrastructure materials (polymers, concrete, engineered composites, etc.) for resilient infrastructure applications.

One of the key research focuses is to evaluate the durability of these materials when exposed to a wide range of environmental conditions. As such, accelerated aging of materials using elevated temperature and humidity is a common practice. The MSSD will benefit from an environmental chamber to condition and age concrete materials for the “Engineered Materials for Resilient Infrastructure” program in projects such as “Assessing Pyrrhotite in Concrete”, “Forward Looking Building Codes”, and “Additive Manufacturing with Cement Based Materials” as well as polymeric materials for the “Measurement Science for Service Life Prediction of Polymeric Components Used in PV Systems”.

Purpose/Objective: The purpose of this requirement is to obtain an Environmental Chamber to reliably condition materials for testing and perform accelerated aging tests. The environmental chamber shall be capable of conditioning infrastructure materials such as concrete specimens as well as cementitious and polymeric materials. The MSSD is anticipating an expansion of its infrastructure materials testing capabilities.

II. MINIMUM REQUIREMENTS

The Contractor shall provide an Environmental Chamber that meets all technical specifications identified below. All items must be new. Used or remanufactured equipment will not be considered for award. Experimental, prototype, or custom items will not be considered. The use of “gray market” components are not authorized for sale in the U.S. by the Contractor is not acceptable. All line items shall be shipped in the original manufacturer’s packaging and include all original documentation and software, when applicable.

III. DELIVERY REQUIREMENTS

Delivery shall be F.O.B Destination and shall occur in accordance with the manufacturer’s or vendor’s standard commercial lead time not to exceed 12 weeks after receipt of an order.

FOB Destination means: The contractor shall pack and mark the shipment in conformance with carrier requirements, deliver the shipment in good order and condition to the point of delivery specified in the purchase order, be responsible for any loss of and/or damage to the goods occurring before receipt and acceptance of the shipment by the consignee at the delivery point specified in the purchase order; and pay all charges to the specified point of delivery.

Delivery shall be made to the NIST Shipping and Receiving address identified below. The delivery will then be directed to the equipment’s final destination, also identified below.

NIST Shipping & Receiving 100 Bureau Drive Building 301 Gaithersburg, MD 20899-0001

NIST Final Equipment Destination:

The National Institute of Standards and Technology 100 Bureau Drive, Building 226, Room B363 Gaithersburg, MD 20899-1640

No installation or training shall be required by the Contractor.

IV. INSPECTION & ACCEPTANCE

In addition to the inspection and acceptance terms articulated in 52.212-4, the Government reserves the right to perform such performance tests and evaluations as defined below to verify specified system performance. Such tests and evaluations, if performed, shall be conducted within the environment that the system is to be operated. The Contractor has the right to be present during the tests and evaluations, if performed, at the Contractor’s expense. Inspection and Acceptance shall take place on the NIST Gaithersburg campus in building 226.

Performance Tests:

1. Ensure that the equipment is operational and has no defects or missing parts.

NIST may choose at its discretion to forego this part of acceptance testing.

A visual inspection of the equipment will be performed by the NIST Subject Matter Expert (SME) to identify surface defects or any form of indication that any equipment was damaged during transport to NIST. The Government shall have sole discretion to require repair or replacement of damaged and/or nonconforming supplies at no cost to the Government. The Government at any time prior to acceptance shall reject the equipment due to defects and/or nonconformance. The vendor is responsible for latent defects discovered any time after final inspection. However, the extent of its liability shall be prorated over the useful life of the equipment.

Ownership of the equipment shall transfer to NIST upon acceptance by the Government.

The Government will test, inspect, and accept or reject the equipment within 10 business days after delivery to ensure that it conforms to the requirements identified in this Requirements document. If all performance testing, as described below, is approved and all other requirements are met and the equipment is operational, the product shall be accepted. of the receipt of the equipment unless otherwise indicated above. The Government reserves the right to conduct quality assurance testing to confirm that a given instrument(s) meets the manufacturer’s and/or the Government’s performance specifications. It is anticipated that the equipment will meet all manufacturer’s specifications and/or the Government’s performance specifications identified in the most recent operations and maintenance manual for each piece of equipment and/or in this document.

V. WARRANTY

The contractor shall warranty the entire system for a period of a minimum of 1 YEAR after receipt of the equipment and shall be in accordance with terms in FAR 52.212-4. Warranty at a minimum shall include the following:

To be free of defects in materials and workmanship for a period of ONE (1) year from the date of the original shipment.
