This specification does not purport to address all of the safety issues associated with its use. The user is responsible to consult appropriat
4、e safety and health practices and to determine the applicability of regulatory limits prior to use. Change Notice: Changed to New MPAPS format; Combined GS, GI, PP, NPP. 1.0 GENERAL: Implementation of this standard must be in accordance with the policies and procedures outlined in MPAPS S-A-0.101. T
5、here may also be supplemental group instructions in regard to use of metric standards that should be taken into account. In formulating this standard for metric split pins, considerable investigation was devoted to an effort to establish interchangeability with the inch series pins in order to avoid
6、 the creation of separate part numbers, records, inventories, etc. However, significant dimensional differences in most sizes, primarily in head dimensions and recommended hole sizes, preclude this possibility. This specification contains the essentials of the following standards: International Orga
7、nization for Standardization: ISO R 1234 Association Francaise de Normalisation: NF E27-487 British Standards Institute: BS 1574 Deutsche Normen: DIN 94 Standards Association of Australia: AS 1236 The inclusion of dimensional data is not intended to imply that all the pins described are stock produc
8、tion sizes. Inch series split (cotter) pins may be found in MPAPS S-J-1.101-GS/PL. 2.0 DESIGN CONSIDERATION: Split pins are normally used to position and lock parts in alignment. They are also used as locking devices for other features such as clevis pins, shafts, threaded rods, etc. The optimum usa
9、ge of split pins is to lock slotted nuts. In these applications, the pin should be of sufficient length to provide a minimum of 6 mm protrusion of the longer leg beyond the nut flat. This allows adequate grip for bending the pin legs at installation. 3.0 METRIC-INCH RELATED SIZES: During the inch to
10、 metric design conversion period, the following chart of related sizes may be of value for handy reference. This information is not to be considered as recommended size substitutions but only as a means of quickly determining approximate dimensional equivalents. NUMBER: MPAPS S-JM-1.101-GS/PL TITLE:

18、tion at the juncture of head and shank. 8.0 POINTS: All points will be the extended prong. The ends of points will not be open and any gaps occurring between the prongs along the shank portion of pins beyond the point will not exceed 0.4 mm. The lateral misalignment of prongs over the entire length
19、will not exceed 0.4 mm. 9.0 LENGTH: The length (L) will be measured parallel to the axis of pin, from the plane of contact of a ring gage with the head of pin (see Figure 1) to the end of shortest prong. The ring gage will have a hole or diameter equal to the nominal pin size within a tolerance of 0
20、.03 mm. The permissible break or rounding at the gaging edges of hole will not exceed 0.13 mm. Length measurement will be taken with pin inserted into gage under finger force not to exceed 2N. 10.0 TOLERANCE ON LENGTH: The tolerance on length will be as tabulated below: Dimensions in millimeters: No
