About this file
This document contains the technical specifications for an Altitude/Humidity/Temperature Chamber required by the Defense Logistics Agency (DLA) Land and Maritime Engineering & Technical Support Directorate Product Test Center Division, Electronics Lab in Columbus, Ohio. The chamber must have a minimum 16 cubic foot capacity and be capable of simulating altitudes up to 100,000 feet, with simultaneous temperature and humidity control. Key requirements include a temperature range of -68°C to +190°C, cooling and heating rates of 60 minutes or less, a humidity range of 10% to 95%, and other specifications for power, insulation, safety features, training, and installation. The chamber must be new, with a 1-year warranty, and have been on the market for a minimum of 3 years. The contractor must provide references, spare parts, and on-site installation, training, and acceptance testing. Pricing for shipping, NIST calibration, and an extended service contract are also required.
