- Description
- The Office of Acquisition and Agreement Management (OAAM), of the National Institute of Standards and Technology (NIST), on behalf of the Engineering Laboratory (EL), intends to negotiate on a sole-source basis with Medtherm Corporation, under the authority of 41 US 3304(a)(1), for water-cooled Schmidt-Boelter heat flux gauges. Background Information and Basis for Sole Source The National Institute of Standards and Technology's (NIST's) Flammability Reduction Group determines material properties (e.g. thermal conductivity) and measures constituent processes (e.g. flame to surface heat flux; sample mass loss rate) controlling material response in typical fire scenarios. As part of an ongoing project, the Flammability Reduction Group is studying anaerobic pyrolysis and surface flame spread over natural and synthetic polymers as well as composite materials. Flame spread rate is governed by positive feedback between coupled processes of gas phase combustion (flame heat transfer to the solid) and condensed phase pyrolysis (heat transfer through and degradation of the solid). Detailed measurement and understanding of these processes will allow for the development and validation of models capable of predicting material flammability performance. A necessary technology to accomplish these measurements is a flame spread apparatus, which consists of a water-cooled Schmidt-Boelter heat flux gauge. Market research confirmed that Medtherm is the only manufacturer capable of meeting the required size, sensitivity, body shape/design, and ZnSe radiation windows required for the aforementioned project. Description of Requirement NIST requires the following water cooled Schmidt-Boelter heat flux gauges: •One (1x) 1/8 inch diameter, smooth/straight body, total heat flux gauge with surface thermocouple (0 - 75 kW m-2 working range) •One (1x) 1/4 inch diameter, smooth/straight body, total heat flux gauge, with surface thermocouple (0 - 75 kW m-2 working range) •Three (3x) 1/4 inch diameter, smooth/straight body, total heat flux gauges, without surface thermocouple (0 - 75 kW m-2 working range) •One (1x) 3/8 inch diameter, smooth/straight body, total heat flux gauge with surface thermocouple (0 - 75 kW m-2 working range) •Two (2x) 3/8 inch diameter, smooth/straight body, total heat flux gauges without surface thermocouple (0 - 75 kW m-2 working range) •Three (3x) cans of optical black coating to repaint the surface of heat flux gauges after cleaning ¼ inch diameter, two window options, with or without thermocouple •One (1x) 1/4 inch diameter, smooth/straight body radiometer [total heat flux gauge with 150° ZnSe window] with surface thermocouple (0 - 75 kW m-2 working range) •One (1x) 1/4 inch diameter, smooth/straight body radiometer [total heat flux gauge with 150° ZnSe window] without surface thermocouple (0 - 75 kW m-2 working range) •One (1x) 1/4 inch diameter, smooth/straight body radiometer [total heat flux gauge with 150° CaF2 window] with surface thermocouple (0 - 75 kW m-2 working range) •One (1x) 1/4 inch diameter, smooth/straight body radiometer [total heat flux gauge with 150° CaF2 window] without surface thermocouple (0 - 75 kW m-2 working range) ⅜ inch diameter, two window options, with or without thermocouple •One (1x) 3/8 inch diameter, smooth/straight body radiometer [total heat flux gauge with removable 150° ZnSe window] with surface thermocouple (0 - 75 kW m-2 working range) •One (1x) 3/8 inch diameter, smooth/straight body radiometer [total heat flux gauge with removable 150° ZnSe window] without surface thermocouple (0 - 75 kW m-2 working range) •One (1x) 3/8 inch diameter, smooth/straight body radiometer [total heat flux gauge with removable 150° CaF2 window] with surface thermocouple (0 - 75 kW m-2 working range) •One (1x) 3/8 inch diameter, smooth/straight body radiometer [total heat flux gauge with removable 150° CaF2 window] without surface thermocouple (0 - 75 kW m-2 working range) At a minimum, the heat flux gauges must meet the following specifications: •Device shall have provisions for water cooling of the gauge body •Device output voltage shall be linearly proportional to net heat transfer rate into gauge surface; maximum non-linearity +/- 2 % of full range •Device shall be calibrated in accordance with ANSI/NCSL Z540-1 and ISO/IEC 17025 with calibrations made against a blackbody or a reference gauge traceable to NIST standards. •Device shall have a time constant (response) of no more than 250 ms •Outer diameters of each heat flux gauge shall match the specifications provided in the scope of work (Section II) •Device shall have a smooth body (no threads or flange) •Device shall be constructed in a manner to ensure accuracy, ruggedness, and reliability throughout repeated and continued setup and use in a fire environment. More specifically, each heat flux gauge (i.e. all configurations, sizes, radiation windows) must be able to operate continuously (minimum of 30 minutes during each use) in a fire environment (specifically with direct flame impingement, with heat fluxes up to 75 kW m-2, on the surface of the heat flux gauge) without damage or degradation to any components of the gauge (provided that adequate water flow is supplied to the measurement device) •Sensor absorptance shall be at least 0.95, nominal, from 0.6 to 15 μm •When installed, window attachments (used to convert total heat flux gauge to radiation heat flux gauge) shall have a viewing angle of no less than 150° •When installed, window attachments (used to convert total heat flux gauge to radiation heat flux gauge) shall provide a flat transmittance of at least 0.7 from 0.7 to 17 μm (ZnSe) OR 0.9 from 0.4 to 10 μm (CaF¬2) •One-Year Warranty The North American Classification System (NAICS) code for this acquisition is 334519 - Other Measuring and Controlling Device Manufacturing. The small business size standard is 500 employees. No solicitation package will be issued. This notice of intent is not a request for competitive quotations; however, responses received by 5:00 p.m. Eastern Time on June 13, 2017 will be considered by the Government. A determination by the Government not to compete the proposed acquisition based upon responses to this notice is solely within the discretion of the Government. Information received will normally be considered solely for the purpose of determining whether to conduct a competitive procurement. Interested parties that believe they could satisfy the requirements listed above for NIST may clearly and unambiguously identify their capability to do so in writing on or before the response date for this notice. This notice of intent is not a solicitation. Any questions regarding this notice must be submitted in writing via email to Adam Powell at adam.powell@nist.gov. All responses to this notice of intent must be submitted so that they are received at adam.powell@nist.gov no later than the aforementioned due date.
