TO 00-20-14 30 SEPTEMBER 2011 - Wright-Patterson Air Force Base

30 September 2011 TO 00-20-14e. When calibrating in extreme environmental conditions, care should be taken to ensure the test uncertainty ratiofor each measurement performed in the calibration (including the effects of any temperature coefficients) isequal to or better than the test uncertainty ratio in the calibration authority.3.9.5.4 Environmental conditions must be monitored for the calibration. The calibration technician must determine howfrequently the calibration environment should be monitored/checked based on the stability of the calibration environment,the length (time) of the calibration, and the sensitivity of the equipment involved in the calibration to fluctuations in thecalibration environment. The calibration environment should be monitored/checked frequently enough to provideassurance that the calibration environment does not adversely impact the calibration process/results. Record the worstobserved temperature/humidity in the PMEL MIS.3.9.5.5 In all cases, PMELs shall conform to the maintenance TO or manufacturer’s data regarding any environmentallimitations or temperature coefficients of any item used in a measurement setup. The calibration authority may statespecific environmental conditions, which shall be met, for the calibration.3.10 PMEL MANAGEMENT RESPONSIBILITIES.The PMEL shall be organized and shall operate in such a way that permanent, temporary and mobile facilities meet therequirements of this TO.3.10.1 Responsibilities of PMEL Commanders and Senior Level Management. Commanders and Managers in thePMEL chain of command shall ensure that:a. The PMEL is maintained in a condition that facilitates effective mission performance. This includes an adequateenvironmental system.b. TMDE requiring calibration is not used unless it has been calibrated and that it is removed from service once thecalibration due date has expired.c. Special attention is placed on personnel proficiency, PMEL manning, environmental control, quality assurance,materiel resources and use of technical directives.d. The PMEL provides maximum support to Air Force activities, other federal agencies, contractors (authorized toreceive such support) and security assistance programs under the guidelines of AFI 25-201, AFI 21-113 and AFI99-103 (Capabilities Based Test and Evaluation).e. TMDE is calibrated and certified as prescribed in this TO, AFI 21-113, applicable CMSs, and TO 33K-1-100-1/-2.f. Vehicles used to transport TMDE are equipped to provide full protection to TMDE from damage that may occurfrom weather, vibration or shock.g. When PMEL measurement standards are not maintained or authorized at an installation or on an instrumentationship, affected TMDE shall be calibrated by a PMEL possessing the required capability. Support agreements maybe negotiated between the site or base and the supporting activity as needed. Reference DoDI 4000.19(Interservice and Intragovernmental Support) and AFI 25-201.h. Continuing problems with PMEL customers regarding timely delivery of TMDE for scheduled calibration shallbe elevated for resolution if the supervisor responsible for the OWC quality control cannot obtain results.i. PMEL intermediate off-equipment TMDE maintenance production requirements are identified in operationsplans when applicable.j. The PMEL shall have managerial staff with the authority and resources needed to discharge their duties.3-21
