      5.1.3       Environmental Requirements

      Spring pins comply with the DKBA2332 Environmental Specifications of Huawei Purchased Materials.

      5.2             Performance Requirements and Inspection Methods

      5.2.1       Performance Requirements

      A spring pin resumes smoothly after being pushed.

      A spring pin does not extrude above the socket after being pulled out without rotating and sunkens after you pull out and rotate it, as shown in Figure 5-3.

      Figure 5-3 Performance requirements for a spring pin

      After being pulled out, the pin snaps in position by rotating the non-threaded dowel shaft within 30 degrees.

      5.2.2       Appearance Requirements

      The surface is clean, flat, and smooth, as shown in Figure 1.

      5.2.3       Reliability Requirements

      The riveted part is secure and does not tilt.

      The pulling force of the pin shaft and the pin cover is greater than or equal to 400 N.

      Test the mechanical performance and rivet force by referring to the following table.

      Environmental testing requirements:

      Stainless steel parts: meet the performance requirements DKBA0.450.0067 passivation of   stainless steel.

      Spring after-sales portfolio requirements: in accordance with IEC 68-2-30 (or GB / T 2423.4)  alternating hot and humid 6 cycles (6 days), without any visible corrosion conditions.

      Determine other unspecified parameters by referring to the DKBA04800128 Technical Requirements for Riveted Fasteners.

      6.    Inspection Rules

      The inspection rules are applicable to the incoming materials of Huawei and comply with the regulations of the quality department of the Mechanical Power Environment Department (MPE) System Department Huawei. The undefined products are inspected in batches and the single sampling plan of the GB2828 batch inspection is used.

      7.    Description

      The MPE System Department of Huawei reserves the right to interpret the technical requirements.

      If there is any disagreement, the arbitration is subject to the technical requirements.
