1 TEXAS DEPARTMENT OF TRANSPORTATION GENERAL SERVICES DIVISION CABINET, CORROSION TESTING PUBLICATION This specification is a product of the Texas Department of Transportation (TxDOT). It is the practice of TxDOT to support other entities by making this specification available through the National Institute of Governmental Purchasing (NIGP). This specification may not be sold for profit or monetary gain. If this specification is altered in any way, the header, and any and all references to TxDOT must be removed. TxDOT does not assume nor accept any liability when this specification is used in the procurement process by any other entity. PART I GENERAL CLAUSES AND CONDITIONS 1. The equipment furnished under this specification shall be the latest improved model in current production, as offered to commercial trade, and shall be of quality workmanship and material. The respondent represents that all equipment offered under this specification shall be new. USED, SHOPWORN, DEMONSTRATOR, PROTOTYPE, REMANUFACTURED, RECONDITIONED OR DISCONTINUED MODELS ARE NOT ACCEPTABLE. 2. Respondent should submit with the solicitation or have on file with TxDOT, Austin, Texas, the latest printed literature and detailed specifications on equipment the respondent proposes to furnish. This literature is for informational purposes only. 3. All parts not specifically mentioned which are necessary for the unit to be complete and ready for operation or which are normally furnished as standard equipment shall be furnished by the vendor. All parts shall conform in strength, quality and workmanship to the accepted standard of the industry. 4. The unit provided shall meet or exceed all Federal and state of Texas safety, health, lighting and noise regulations and standards in effect and applicable to equipment furnished at the time of manufacture. 5. It is the intent of TxDOT to purchase goods, equipment and services having the least adverse environmental impact, within the constraints of statutory purchasing requirements, TxDOT need, availability, and sound economical considerations. Suggested changes and environmental enhancements for possible inclusion in future revisions of this specification are encouraged. 6. TxDOT encourages all manufacturers to comply voluntarily with the Society of Automotive Engineers (SAE) Recommended Practice for marking of plastic parts per current SAE J1344 standard. All plastic components furnished to this specification should have an imprinted SAE symbol identifying the resin composition of the component so that the item can be recycled after its useful life. Manufacturers are encouraged to use recycled plastics and materials in the manufacture of their products in order to conserve natural resources, energy and landfill space. Respondents should note that future specification revisions may require mandatory compliance with the SAE plastic coding system. 7. TxDOT is committed to procuring quality goods and equipment. We encourage manufacturers to adopt the International Organization for Standardization (ISO) 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. 1-5

Where any conflict between the two stated measurements may occur, the measurements provided in the English system shall supersede those provided in the metric system. PART II SPECIFICATIONS 1. SCOPE: This specification describes a cyclic corrosion cabinet for use in a traffic materials laboratory to perform accelerated corrosion testing on different materials in various corrosive environments. The cabinet shall meet or exceed the following: EXAMPLE: Atlas Material Testing Solutions Model No. CCX 3000 Auto Technology Co. Model No. CCT-NC-30 or TxDOT approved equal. NOTICE TO RESPONDENTS: Any example shown is listed to show type and class of equipment desired. Respondents are cautioned to read the specification carefully, as there may be special requirements not commonly offered by the manufacturer. DO NOT ASSUME YOUR STANDARD EQUIPMENT MEETS ALL OF THE DETAILED SPECIFICATION REQUIREMENTS MERELY BECAUSE IT IS LISTED AS AN EXAMPLE. Respondents are 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 cyclic corrosion cabinet shall be equipped with a laptop computer control which shall be programmable to automatically cycle and replicate the following test conditions: 2.1. Salt or chemical fog (saturated relative humidity (RH)) 2.2. Water fog (saturated RH) 2.3. Dry-off 2.4. Dwell (period of rest where no action is taken) 2.5. High humidity (moist heat) 2.6. Direct spray (impingement) using salt or chemical spray 2.7. High temperature 2.8. Controllable and adjustable relative humidity per testing requirements stated in Paragraph Ambient temperature and RH 3. TESTING REQUIREMENTS: Cabinet shall be equipped to perform the following American Society for Testing and Materials (ASTM), and SAE tests, latest version: 3.1. ASTM B ASTM G85-02E SAE-J CABINET REQUIREMENTS: Cabinet shall be constructed of a corrosion resistant material such as fiber reinforced plastic. Interior space of the cabinet shall contain a test chamber in which all testing cycles shall be performed TEST CHAMBER: Interior walls shall be gel coated to prevent corrosive deterioration and shall be defined by the following boundaries: Top: Plane-of-entry of the fog or spray. Space above the plane shall have laterally moving fog or spray, not downward moving condensation. 2-5

3 Bottom: Lowest point at which a sample receives direct condensation of fog or spray without being shielded by heating elements, false floors, another sample, or other barrier Sides: Interior walls of the cabinet walls on which condensation occurs SOLUTION RESERVOIR: Shall be gel coated to prevent corrosive deterioration and shall be a minimum of 60 gallons FOG DISPERSION UNIT: Shall perform the following functions: Provide uniform fog throughout the test chamber Baffle the fog both horizontally and vertically throughout the test chamber Be raised or lowered manually Spray electrolyte solutions with a 12 nozzle spray bar header directly onto the samples 4.4. BUBBLE TOWER: Shall create corrosive fog and high humidity cycle HEATERS: Shall maintain the programmed temperature within the test chamber POWER EXHAUST BLOWER: Shall exhaust salt fog enabling the chamber to begin the drying cycle CLEAR FRONT COVER: Shall allow viewing of all test specimens within the test chamber and shall meet the following requirements: A contact switch and controller shall be installed to shut air flow to the bubble tower when front cover is raised, and open air flow to the bubble tower when cover is closed for testing to resume Dual magnetic gaskets shall be installed on both the underside of the cover and the top of the cabinet to seal the test chamber and prevent the escape of fog TESTING VOLUME: The testing volume of the cabinet is defined as the actual, usable testing space of the cabinet, not including the space below the exposure zone or the space within the angled cover and shall be a minimum of 30 cubic feet (.85 cm³) TESTING PLANE: The testing plane of the cabinet is defined as the length by width measured inside the test chamber at the sample position and shall be a minimum of 15 square feet (1.39 sqm) ACCESS: Cabinet shall have only front access for sample positioning, maintenance and calibration SAMPLE: Shall be situated lower than fog point-of-entry into the cabinet. 5.
