Foreword
This Standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This Standard replaces GB/T 7094-2002, Vibration (Sinusoidal) Test Method for
Electrical Installations in Ships. Compared with GB/T 7094-2002, the main technical
changes of this Standard, except editorial changes, are as follows.
-- the selection of working positions during the vibration test of samples is changed;
-- the contents including acceleration sensor is added in vibration response analysis;
-- the vibration test duration is changed to 90 min;
-- when the discrete frequency test is replaced by the sweep frequency test, it
specifies the range of sweep frequency;
-- it adds the requirement for the temperature 600˚C under very special vibration
conditions;
-- in the vibration test, the performance test for samples in accordance with product
specifications is changed into the functional test; and
-- it adds the requirement that the vibration test equipment shall track resonant
frequency.
This Standard was proposed by and shall be under the jurisdiction of China Electrical
Equipment Industry Association.
The responsible drafting organizations of this Standard. Shanghai Electrical Apparatus
Research Institute, China Classification Society Shanghai Standard Research Institute
and China Classification Society Shanghai Branch.

3 Terms and Definitions
For the purpose of this document, the terms and definitions defined in GB/T 2422 shall
apply.
4 Mounting of Samples
Samples shall be mounted on the shaking table rigidly in accordance with the mounting
state in actual use. When there are multiple mounting states for samples, the most
unfavorable mounting state shall be selected in general cases. When it is incapable of
mounting them directly, they shall be fixed on the shaking table with a mounting clip.
During mounting, samples without a shock absorber shall be fixed on the shaking table
rigidly; samples with a shock absorber shall be mounted on the shaking table together
with the shock absorber, which shall be specified in the product specifications.
