Therefore, the attached Q&A document is amended to this SSN. All other terms and provisions remain unchanged. END. INTRODUCTION This is a Sources Sought notice. This is NOT a solicitation for proposals, proposal abstracts, or quotations. The purpose of this notice is to obtain information regarding the availability and capability of qualified business sources. This notice is strictly for market research and information purposes only. Your responses will assist the Government in determining the appropriate acquisition method, including whether a set-aside is possible. NIST is seeking responses from all responsible small business concerns. Small businesses are defined under the associated NAICS code for this effort, 334519 (Other Measuring and Controlling Device Manufacturing), as those domestic sources not exceeding the average number of 600 employees. Background: The Infrastructure Materials Group (IMG) of the Materials and Structural Systems Division (MSSD) in the Engineering Laboratory (EL) of the National Institute of Standards and Technology (NIST) studies the durability and service life of materials, components, and systems composing US buildings and road- and waterways, and pipelines for resilient infrastructure. MSSD currently performs thermal analysis of infrastructure materials to understand thermal characteristics relevant to their use. Differential Scanning Calorimetry (DSC) is a system that measures heat flow signals to allow users to better understand thermal events (chemical reactions, phase transitions, glass transitions, etc.) of materials. MSSD uses DSC to understand the thermal characteristics of infrastructure materials as they relate to processing, for example the cure kinetics of thermoset polymers and kinetics of the setting of cementitious materials. MSSD uses DSC also to investigate field performance, for example temperature-based transitions (e.g., glass-transitions) which may influence behavior. Thermogravimetric Analysis (TGA) is a system that measures the weight/mass of a sample as a function of temperature. Changes in mass are indicative of reactions. MSSD uses TGA to understand the degradation of infrastructure materials with temperature, volatiles evolved in processing, and other compositional information (e.g., carbon content). The MSSD currently owns and operates a DSC “Q 2000” and TGA “Q 500,” which were manufactured and produced by TA Instruments – Waters. The DSC Q 2000 and TGA Q 500 are at the end of their service life. A new DSC and a new TGA are therefore required. Scope of Requirement: NIST is seeking information from all responsible small business concerns capable of developing and producing a new differential scanning calorimeter with sub-ambient cooling capability and a new thermogravimetric analyzer. These new systems will replace the existing, outdated DSC Q 2000 and TGA Q 500 instruments. A dedicated DSC for measuring the heat flow into samples as a function of time and temperature is required. Similarly, a dedicated TGA is required to measure the mass loss of samples as a function of time and temperature. The two instruments are required to ensure accurate measurements and flexibility in their use, i.e., running experiments on the two instruments simultaneously. The Contractor shall deliver a quantity of one DSC and associated computer system, a quantity of one (1) cooling system for the DSC, and a quantity of one (1) TGA and associated computer system. The delivery shall be inclusive of FOB Destination delivery, installation, warranty and training. Minimum Requirements: The Contractor shall provide a system that meets, or exceeds, 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 that are not authorized for sale in the U.S. by the Contractor are not acceptable. All line items shall be shipped in the original manufacturer’s packaging and include all original documentation and software, when applicable. Requirement 0001: DSC and the Associated Computer System Description: The contractor shall provide a DSC and computer for running the instrument and subsequent thermal analysis, in accordance with the essential characteristics identified in this Statement of Requirements. The DSC shall be a heat flux design, as opposed to a power compensated design. The DSC shall have a large temperature range, as specified, for versatility in testing the wide variety of infrastructure materials (e.g., gasket materials of pipe joints, cementitious materials). The DSC shall have a robust cell and a flat instrumental baseline with low variability between runs, as specified.
