66 -- COMBUSTIBLE GAS AND OXYGEN ANALYZER SOL N68335-96-RFI-617 DUE 091596 POC B. Kephart Code 213BK, (908) 323-2065. The Naval Air Warfare Center Aircraft Division is seeking sources and/or information on a combustible gas and oxygen analyzer to detect, measure and indicate concentration of oxygen and combustible gases emitted from JP-5, JP-8, JA-1, JA-1A or similar military or commercial jet fuels. The combustible gas and oxygen analyzer is to be portable handheld commercial off-the-shelf (COTS) gas analyzer. The analyzer shall measure and digitally display the gas concentrations in the following units: oxygen in percent by volume, and combustible gases by percent Lower Explosive Limit (LEL) and Permissible Exposure Limit (PEL) in parts per million (ppm). The minimum acceptable accuracy and range for the analyzer are as follows: (a) Oxygen, +/-0.5 percent oxygen from 0-25 percent oxygen by volume; (b) Combustible Gases (LEL), +/-2 pecent from 0-100 percent LEL; (c) Combustible Gases (ppm), best commercial accuracy from 0-10000 ppm. Descriptive literature should specify the best obtainable commercial accuracy (e.g. +/-5ppm, +0.5/-0.0 percent oxygen, etc.) and resolution (e.g. LEL in 1% increments, ppm in 20 ppm increments, etc.) of the analyzer. The range of oxygen and combustible gas concentration the analyzer can measure or indicate should also be included. The analyzer shall have audible alarms for low and high oxygen concentrations, high ppm and percent LEL for combustible gases, low battery and sensor malfunction. The audible alarms shall be supplemented with aditional alarms (e.g. visual indicators) for working on high noise enviroments. The analyzer shall not be greater than 26 centimeters in any direction with a maximum volume of 5000 cubic centimeters. The weight of the unit shall be less than 2.5 kilograms. The analyzer shall operated on standard commercial alkaline batteries (i.e. AAA, AA, A, C or D size cells). The analyzer shall draw air samples from remote locations by using an automated sampling pump and a minimum 2 meter length sampling hose. The sampling hose shall be constructed of non-fuel absorbent material and contain features to prevent liquids from being drawn into the system. In addition, the system shall be supplied with a calibration kit. The kit shall contain all necessary items to calibrate the unit and a carrying case to hold all the kit's elements and the gas analyzer as well. The calibration controls or adjustment devices shall be incorporated in locations easily assessible by the user. The system shall be certified to be instrinsically safe for use in Class 1, Division 1, Group A, B, C and D atmospheres by a nationally recognized testing laboratory. The system shall be resistant to Electromagnetic Interference (EMI) and other enviromental conditions present in aircraft carrier hangar bays or during shore aircraft fuel cell repair operations. The electric field strength of the hangar deck is 10 Volt/meter over a frequency range of 1 Mhz to 1 Ghz. The integrated logistics elements to support the analyzer shall include commercial technical manuals, calibration requirements, interim parts support, supplemental provisioning documentation and training. The technical manual should include an illustrated parts list. Respondents to this request for information are invited to submit a statement of general interest and a description of any currently available system which meets our requirements. Any comments provided may or may not be included in a formal solicitation. NAWCADLKE is interested in determining if this item, along with the technical information required to support the equipment, in available in the commercial marketplace and meets the definition of commercial items as defined in the Federal Acquisition Regulations (FAR) Part 12. The technical information would be required to include a technical manual that would contain operation instructions, maintenance instructions and illustrated parts brekdown. Other data required would be supplemental provisioning technical documentation, a provisioning parts list, provisioning and other procurement screening data and a support material list. Those sources interested in the request for information are invited to submit their information and a description of any currently available product that meets our requirements. This is not a request for proposal and no solicitation is available. The Government will not pay for any information requested in response to this RFI nor will the Government compensate any respondent for any cost incurred in developing the information provided to the Government.
