TO 00-20-14 30 September 2011circuitry/equipment to remove dust. Techniques for cleaning electronic equipment are provided in TO 00-25-234. Thesetechniques may also be applied for electromechanical and physical standards when applicable. Oxygen TMDE shall becertified as clean by the user prior to shipment to the PMEL.NOTEOxygen gages shall contain the warning OXYGEN-USE NO OIL printed on the faceof the gage by the manufacturer or by use of the OXYGEN- USE NO OIL decal partnumber 69A52267 (TO 15X-1-102, General Care and Cleaning of Oxygen Gaugesand Oxygen Device Related Test Equipment) or an equivalent statement of oxygenservice. If the gage does not have the OXYGEN-USE NO OIL warning or decal orequivalent statement of oxygen service printed on the face or affixed to the gage, thePMEL shall not include the “Not Oxygen Clean” statement on the certification label.3.8.4 PMEL Tracking of TMDE. Each item of equipment shall be labeled, marked or otherwise identified to indicate itscalibration status. Records shall be maintained for each item of equipment and all materials significant to the calibrationsor verifications performed. All items having PAMS ID numbers that require calibration when used to accomplish thecalibration shall be entered into the PAMS or alternate management information system traceability listing (calibrationdetail listing in PAMS). TMDE used for preliminary steps, but not listed as a standard in the calibration procedure, doesnot require listing. The records shall be stored and held secure and in confidence to the customer for a minimum periodof one year or the length of one calibration interval if the calibration interval exceeds one year. The intent is to have atleast the last record in the file. The records shall include as a minimum:a. Nomenclatureb. Manufacturer, type identification and serial number or other unique identificationc. Current location, where appropriated. Where applicable, date calibrated, results of calibration and/or verifications, and date due calibratione. Details of maintenance carried out to date and planned for the futuref. History of any damage, malfunction, modification or repairg. The identity of the certifying technician3.8.5 PMEL Handling of TMDE.a. The PMEL shall have a system for uniquely identifying the items to be calibrated, to ensure there can be noconfusion regarding the identity of such items at any time.b. Upon receipt of the TMDE for calibration, any abnormalities or departures from standard condition as prescribedin the relevant calibration method shall be recorded on an AFTO Form 350 or equivalent document. Wherethere is any doubt as to the item’s suitability for calibration, where the item does not conform to the descriptionprovided, or where any limited or special calibration required is not fully specified, the PMEL shall consult thecustomer for further instruction before proceeding. The PMEL shall establish whether the item has received allnecessary preparation, or whether the customer requires preparation to be undertaken or arranged by the PMEL.3.9 PMEL MOBILE/ON-SITE MEASUREMENT CAPABILITIES.3.9.1 Transportable Field Calibration Unit (TFCU). The TFCU consists of working standards, TMDE and accessories.These items are mounted in shockproof transportable cases. The cases serve as equipment racks during operation andprovide protection during transit. The TFCU is used to augment a PMEL to provide on-site calibration support. ThePMELs that possess and operate TFCUs are identified in Section 12.3-18
