PNEUMATIC PNEUMATIC ST STANDARD ANDARDS S for INDUSTRIAL EQUIPMENT and GENERAL PURPOSE MACHINE TOOLS P-1-1975 FOREWORD Users and suppliers of industrial equipment, as well as the component manufacturers, have long recognized that the safety of personnel and uninterrupted production are of cardinal importance to the economic growth of industry. The application of pneumatics to industrial equipment resulted in preparation of the first pneumatic standard over 20 years ago. This is the latest revision of that standard. This revision has been written as a General Purpose Pneumatic Standard and has been extended, where noted, to Mass Production Equipment, as well as to the type of engineering considered desirable. This standard is basic in nature, that is, it does not contain any requirements specific to any one industry, industry, company, division, or plant.
All JIC standards are advisory only. only. Their use in industry or trade is entirely voluntary. The JIC assumes no liability for any patent infringements or asserted patent infringements which may result from the use of this standard. Comments or requests for information regarding JIC activities or interpretation of the JIC standards should be addressed to the Secretary of the Joint Industrial Council, 7 901 Westpark Westpark Drive, McLean, VA 22101. Proposals to change this JIC Pneumatic Standard are considered in the Joint Ind ustrial Council meetings held at intervals for this purpose. Future revisions will include application requirements for those fields that become so closely associated with the pneumatic science as to be deemed a part thereof. No additions, revisions, or deletions shall be made hereto when reproduced as the JIC Pneumatic Standard for In dustrial Equipment.
The JIC Pneumatic Standard Committee which prepared this standard was composed of: T.F. Graffy - Chairman Airmatic/Beckett-Harcum W.A. Burton Lawrence Livermore Laboratory C.A.

Field changes are subject to provisions of P1.1 2.3. Section 6 . Purchaser’s drawing numbers assigned to PE3.6 the pneumatic circuit and the equipment to which the circuit is applied, if different, should be shown. Where numbers are not available at the time the inquiry is originated, they should be included with the purchase order or as soon thereafter as assigned. Section 7 . The purchaser should use this section to PE3.7 emphasize particular and previously stated requirements, statements of policy, and general data. Section 8. 8 . The purchaser should list all unusual PE3.8 environmental conditions, required deviations from the specified standard, and additional safety requirements. Applicable labor conditions, unusual operating conditions and/or problems, supply or material handling problems, and other special requirements should also be shown. Section 9 This section should be filled in by the PE3.9 purchaser only where his selection of components is advantageous relative to his inventories, component procurement, and/or his equipment maintenance. Such preference should be based on design requirements, operational experience, and inventory consideration. Information provided in Section 9 of the Data For m should specify general type of function of the equipment or component and should include the rnanufacturer’s name and size, group. or series to which the equipment or components belong (not a specific model designation) in accordance with the p urchaser’s preference. When no equipment preference is specified, the supplier’s choice shall be acceptable. The order of the purchaser ’s preference should be indicated numerically (1.2.3) in the space provided immediately preceding the listing of the preferred component or equipment. When the order of pr eference is omitted, preferred equipment or components listed shall be considered equally acceptable.
