Statement of Work/Specifications Request for Quotation: SB1341‐15‐RQ‐0596

1. Background

The Engineered Fire Safety Group, Fire Research Division, Engineering Laboratory at NIST studies fire phenomenon that affect fire safety in buildings and facilities. In order to study fire phenomena, it is necessary to record high resolution thermal images at high frame rates and store approximately 60 minutes of thermal video. The required system will be used to record thermal images and provide quantitative radiometric data and temperature measurements of electrical equipment such as cables, wires, current transformers, enclosures, cabinets, and circuit breakers. Due to the large temperature range between ambient temperature and fire phenomena, the required system needs to have a temperature range of at least ‐20 °C to 1500 °C. The thermal imaging system will be used to support the completion of tasks in support of the NIST/Nuclear Regulatory Commission (NRC) effort titled

“Instrumentation Circuit Fire Risk Project”.

2. Specific Requirements

The system will be used to record thermal images and provide quantitative radiometric data and temperature measurements of electrical equipment such as cables, wires, current transformers, enclosures, cabinets, and circuit breakers. Due to the large temperature range between ambient temperature and fire phenomena, the system needs to have a temperature range of at least ‐20 °C to

1500 °C.

The thermal imaging system shall be capable of operating without external cooling and shall consist of three (3) main parts: 1) Thermal Imaging Camera/Lens , 2) Image Data Acquisition/Image Analysis
