7. TxDOT is committed to procuring quality goods and equipment. TxDOT encourages manufacturers to adopt the International Organization for Standardization (ISO) 9001-9003 standards, technically equivalent to the current American National Standards Institute/American Society for Quality Control (ANSI/ASQC Q91-93), and obtain certification. Adopting and implementing these standards is considered beneficial to the manufacturer, TxDOT, and the environment. It is TxDOT's position that the total quality management concepts contained within these standards can result in reduced production costs, higher quality products, and more efficient use of energy and natural resources. PART II SPECIFICATIONS 1.

Respondent is cautioned to read the specification carefully, as there may be special requirements not commonly offered by the manufacturer. DO NOT ASSUME STANDARD EQUIPMENT MEETS ALL OF THE DETAILED SPECIFICATION REQUIREMENTS MERELY BECAUSE IT IS LISTED AS AN EXAMPLE. Respondent is cautioned that any unit delivered to the FOB point which does not meet specification in every aspect will not be accepted. 2. FUNCTIONAL REQUIREMENTS: The minimum testing range of thermal conductivity shall be 0.1 W/mK to 100 W/mK and minimum testing range of thermal effusivity shall be 0.1 W s/m 2 K to 19,000 W s/m 2 K. 2.1 The testing temperature of samples shall be between -20 C to +155 C, with the controller in the temperature range of +15 C and +28 C. 2.2 The device shall be based on the principle of transient plane source technique or modified transient plane source technique. 2.3 The test procedure shall be non-destructive and samples shall be reusable after testing. 2.4 There shall be minimum or no device calibration and sample preparation. Calibration shall already be performed in the factory. 2.5 The testing procedure performance shall be a minimum of one test within 20 seconds. 2.6 The input power shall be in the range of 110-230 VAC, 10-15 AMPS fused and 50-60 HZ. 2.7 The minimum sample size shall be 17 mm or less and the maximum sample shall be up to and inclusive of 80 mm in diameter or cube size. 2.8 The minimum sample thickness shall be 0.5 mm with a maximum of 100 mm. 2.9 The device shall work in an ambient environment with a maximum relative humidity of 85%- 90%, non-condensing. 2.10 The device shall have a minimum measurement precision from.5 % to 1% when testing is repeated on the same sample ten times. 2.11 The device shall have a minimum testing accuracy of 3%- 5% when compared to actual physical constant. 2-5
2.12 The device shall become part of TxDOT network. The vendor shall work with TxDOT to meet this requirement. 2.12.1 A laptop computer shall be part of the device, and shall have a processor of greater than 1.5 GHZ speed, a minimum memory of 1024 MB, and a battery lasting more than 3 hours. 2.12.2 Installed operating software and the interface shall be user friendly. It shall run on Windows XP Professional. The software shall have graphic capacity and data file can be easily transferred to Excel file. The acquired data shall populate into current TxDOT database system. 2.13 Shall have an automatic shutdown procedure to protect the device when temperature exceeds 110 degrees F or a voltage surge of 240 VAC is encountered. 2.14 The mean time between failures shall be more than 10,000 hours for a typical operating profile of 5 operating hours per day. 2.15 The sensor shall automatically compensate for variations in sensor temperature. 3.
