Federal Specifications are issued by the General Services Administration and are listed in the GSA “Index of Federal Specifications, Standards and Commercial Item Descriptions.” New military specifications are developed and existing specifications are updated to establish requirements for military-unique products or commercial products that must be substantively modified to include military-unique requirements. If a nongovernment standard exists that contains the basic technical requirements for a product or process, it is referenced in the military specification, and the military specification contains only those additional requirements needed by the Department of Defense. Military specifications are issued by the Department of Defense and are listed in the “Department of Defense Index of Specifications.” d. Proprietary. Proprietary specifications refer to specifications owned by an oil producer or used for acquisition of a product from a lone source. (1) Oil producer. Some proprietary specifications contain confidential trade secrets, and are developed and exclusively controlled by a lubricant producer. Producer specifications published in company brochures, pamphlets, and handbooks contain nonproprietary information and are described in subparagraph 132-a(6) Oil Producers’ Product Data and Specifications. (2) Acquisition. Sometimes a proprietary specification is used as an acquisition method to specify a product that is available from only one source. It identifies a product by manufacturer’s brand name, product number, type, or other unique designation. A specification can be considered proprietary even if brand name is not stated but the product is available from only one source. Specifying by product name is suitable and advantageous when a specific product has proven successful or its use is specified by an equipment manufacturer as an equipment warranty condition. Disadvantages to specifying a product by brand name are that it eliminates competition and the purchaser may pay a premium price. 13-5. Lubricant Consolidation a. General. Older machines tend to operate at slow speeds and light loads. These machines also tend to have large clearances and few lubricating points. Lubrication of such older machines is not as critical, comparatively speaking, as for modern machines that operate at higher speeds, under heavier loads, and with closer mechanical tolerances. A common maintenance practice is to have inventories of several types of lubricant to service both older and newer versions of similar equipment (e.g., speed reducers). This problem is further aggravated by the different types of unrelated equipment operating at a complex facility (e.g., turbines, speed reducers, ropes and chains, etc.), each requiring lubrication. Consolidation of lubricants is usually undertaken to reduce inventories, storage requirements, safety and health hazards, and 13-10 EM 1110-2-1424 28 Feb 99 cost. Consolidation, done properly, is a rational approach to handling the lubrication requirements at a facility while reducing the total number of lubricants in the inventory. b. Manufacturer’s recommendations. Manufacturers may recommend lubricants by brand name or by specifying the lubricant characteristics required for a machine. Depending on the machine, lubricant specifications may be restrictive, or they may be general, allowing considerable latitude. Usually the manufacturer’s warranty will be honored only if the purchaser uses the...
