About this file
This document is a combined synopsis/solicitation for the procurement of two laboratory ovens by the National Institute of Standards and Technology (NIST). The ovens must meet specific requirements, including temperature range, dimensions, weight capacity, and control system functionality. The solicitation is a Request for Quotations (RFQ) under FAR Part 13 Simplified Acquisition Procedures, with a small business set-aside. Quotations are due by 5/27/2024, and the ovens must be delivered and installed within 90 days of award. The Government will award a purchase order to the responsible quoter whose quotation, conforming to the solicitation, is the lowest price, technically acceptable. Quoters must provide documentation demonstrating their product's ability to meet or exceed the minimum specifications, as well as firm-fixed price quotations and other required submissions.

Requirement
Background
The NIST Security Technologies Group requires a pair of laboratory ovens for maintaining elevated conditioning temperatures on ballistic witness materials. These witness materials must be maintained at temperatures in the range of 37 C to 50 C (99 F to 122 F). The new ovens will replace an existing oven that is at end-of-life and which has insufficient size for optimal handling of the witness materials.
The interior dimensions of the ovens must be sufficiently large to accommodate witness material blocks that meet the requirements of ASTM E3004, “Standard Specification for Preparation and Verification of Clay Blocks Used in Ballistic-Resistance Testing of Torso Body Armor”, while the exterior dimensions must allow the ovens to be transported through the existing doorways into the laboratory space where they will be used. The shelves in the ovens must be able to support the weight of the materials, and the control system must be able to maintain the temperature with sufficient accuracy and uniformity.
Minimum Specifications
The ovens must meet the following specifications:
Type: Forced (mechanical) convection oven. The oven shall use electric heating. Note: natural gas, propane, or other fuel-based heating systems are not acceptable.
Temperature:
Minimum temperature: 15 degrees C (27 deg F) above ambient or less.
Preference will be given to ovens capable of 10 degrees C (18 deg F) above ambient or less.
(When used in a laboratory maintained at 22 degrees C (72 deg F), the oven should be capable of maintaining a temperature as low as 37 degrees C (99 deg F))
Maximum temperature: 200 degrees C (390 deg F) or greater.
Temperature uniformity: +/- 3 degrees C (5.5 deg F) or less.
Control Tolerance: +/- 1 degrees C (1.8 deg F) or less.
Dimensions:
Minimum Interior Dimensions:
Interior width: 760 mm (30 in) or larger.
Interior depth: 710 mm (28 in) or larger.
Preference will be given to ovens with a 760 mm (30 in) or larger depth.
Interior height: 1170 mm (46 in) or larger.
Maximum Exterior Dimensions:
The oven must be able to fit through an opening:
1270 mm wide by 2060 mm high (50 in wide by 81 in high).
(It is acceptable that easily removed and replaced components might need to be removed to allow the oven to fit during the installation process; however, if this is the case it should be clearly documented that this is possible)
Exterior width: 2160 mm (85 in) or less.
Exterior height: 2440 mm (96 in) or less.
Weight Capacity:
Each shelf: 90 kg (200 lb) or greater.
Oven total: 200 kg (440 lb) or greater.
Other Mechanical:
Interior material: Stainless steel.
At least two shelves.
Shelves shall be height adjustable.
At least one lead-in (entry) port, ≥ 19 mm (0.75 in) diameter.
Control System:
Digital Controller with 0.1 °C resolution.
Temperature setpoint operation or programmable operation.
Over-temperature alarm and auto-shutoff.
Electrical Requirements:
480 V single or three phase 60 Hz.
Operations manual shall be included (any format acceptable)
Delivery
Delivery shall be FOB Destination and be completed no later than 120 days from the date of award.
Description Quantity Due Date Lab oven meeting the minimum requirements 2 Within 120 Calendar days after award of requirement
Operation Manual 2 At the time of delivery
Testing and Acceptance
The Government Contracting Officer’s Representative will inspect and verify that all minimum specifications have been met for Government acceptance. If either oven fails acceptance, that oven will be removed and returned at the expense of the supplier. The NIST will not incur any cost associated with the removal and return.
Warranty
• Warranty coverage should include the controller, all heaters and fans, mechanical components, and workmanship and construction.
• Warranty shall be for a minimum of one year after Government acceptance has occurred.
