This part of IEC 60749 describes a shock test intended to determine the suitability of component parts for use in electronic equipment which may be subjected to moderately severe shocks as a result of suddenly applied forces or abrupt changes in motion produced by rough handling, transportation, or field operation. Shock of this type may disturb operating normally applicable to cavity-type packages. In general, this mechanical shock test is in conformity with IEC 60068-2-27 but, due to specific requirements of semiconductors, the clauses of this standard apply.
