2 General This test is conducted for the purpose of determining the suitability of connectors and connector assemblies when subjected to shocks such as those that may be expected as a result of rough handling, transportation and operational conditions., This test differs from other shock tests in that the design of the shock machine is not specified, but the half-sine and sawtooth shock pulse waveforms are specified with tolerances. The frequency response of the measuring systems is also specified with tolerances.

EIA Engineering Standards and Publications are designed to serve the public interest through eliminating misunderstandings between manufacturers and purchasers, facilitating interchangeability and improvement of products, and assisting the purchaser in selecting and obtaining with minimum delay the proper product for his particular need. Existence of such Standards and Publications shall not in any respect preclude any member or nonmember of EIA from manufacturing or selling products not conforming to such Standards and Publications, nor shall the existence of such Standards and Publications preclude their voluntary use by those other than EIA members, whether the standard is to be used either domestically or internationally.
3.1 Axis Figure 1 indicates a pictorial view of the axis definitions. The Detail Specification shall indicate the fixturing required or the axis definitions if different than as stated in figure 1. Axis definitions for symmetrical, square and “free” connectors shall be defined in the Detail Specification.
