Many PMELs built or renovated in recent years have not met minimum operating environmentstandards. These
13、facilities cannot be certified by the Air Force Metrology and Calibration Program, resulting inloss of calibration capability at the bases. This manual provides Air Force Civil Engineer standards for design andconstruction of Precision Measurement Equipment Laboratories. Use it as a guide for site s
14、election and design of anew metrology laboratory, or for modification of an existing facility. Only those requirements which directly affectthe accuracy and integrity of the measurements made and are unique to a calibration laboratory are addressed.Criteria in this manual must not be used as sole ju
15、stification to improve an existing facility if the facilitys conditiondoes not adversely affect the environmental requirements for performing measurement traceability. Users shouldcontact AFMETCAL DET 1/ML, 813 Irving-Wick Drive West Suite 4M, Heath OH 43056-6116, and HQAFCESA, Tyndall AFB early in
16、the design phase to ensure their facility will meet or surpass the basic designcriteria.2. Responsibilities:2.1. Headquarters Air Force Civil Engineer Support Agency (HQ AFCESA):2.1.1. Establishes standards and criteria for Air Force PMEL design and construction.2.1.2. Provides technical assistance
17、to the MAJCOMs and bases.2.2. AFMETCAL DET 1/ML: Manages the Air Force Metrology and Calibration program, including the PMELprogram.2.3. Base Civil Engineer:2.3.1. Ensures this manual is referenced in all PMEL project design documents, and reviews A space required for support/administrative areas is
18、 based on the number ofpersonnel working in the PMEL. Support/administrative area figures are not included in Table 1.4.1. Layout. Locate rooms, spaces, and equipment to ensure orderly workflow, and provide security andproperty management. Incompatible areas should not be in close proximity; e.g., e
19、quipment that vibratesshould not be near the calibration/repair area when vibration may affect measurements. Moisture-generatingareas such as restrooms and breakrooms should not be near the calibration/repair area. Limit outside walls inthe calibration/repair area as much as possible. North exposure
20、s and east exposures are preferred. Ensuretraffic from movement of equipment, technicians, and customers is isolated from the calibration/repair area.Where possible, design doors and air locks (paragraph 4.1.2) to allow movement of large PMEL equipment andappropriate material handling equipment with
21、in the facility. With the exception of the air lock doors, designateall exit doors as emergency exits only.Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-AFMAN 32-1094 1 NOVEMBER 1998 5Table 1.
