Scope
GB/T 7094-2016 is the English-translated version of 船用电气设备振动（正弦）试验方法.
This standard sets out the mounting of samples, the test parameters and the test procedure of the vibration (sinusoidal) test for electrical installations in ships.
Clause 1, headed Application Scope, says the standard applies to the vibration (sinusoidal) test for electrical installations in ships, and the page records no exclusion.
Its contents run Foreword, 1 Application Scope, 2 Normative References, 3 Terms and Definitions, 4 Mounting of Samples, 5 Test Parameters, 6 Test Procedure and 7 Performance Evaluation.
Clause 2 cites GB/T 2422 and GB/T 2423.43-2008, and clause 3 applies the terms and definitions defined in GB/T 2422.
Clause 4 requires samples to be mounted rigidly on the shaking table in the mounting state of actual use, the most unfavourable state being chosen in general where a sample has several, with a mounting clip used where direct mounting is impossible, and it requires a sample without a shock absorber to be fixed rigidly while a sample with one is mounted on the table together with the shock absorber, as specified in the product specifications; the copy on the page stops at the end of this clause, so it shows nothing of clauses 5 to 7.
The foreword records that the standard was drafted in accordance with the rules given in GB/T 1.1-2009 and that, against the 2002 edition and apart from editorial changes, the selection of working positions during the vibration test of samples was changed, content including the acceleration sensor was added in vibration response analysis, the test duration was changed to 90 min, the range of sweep frequency was specified for the case where the discrete frequency test is replaced by the sweep frequency test, a requirement was added for the temperature 600 °C under very special vibration conditions, the performance test of samples according to product specifications became a functional test, and the vibration test equipment was required to track the resonant frequency.
It was proposed by and is under the jurisdiction of China Electrical Equipment Industry Association, with Shanghai Electrical Apparatus Research Institute, China Classification Society Shanghai Standard Research Institute and China Classification Society Shanghai Branch as the responsible drafting organizations.
It replaces GB/T 7094-2002, was issued on 29 August 2016 and has applied since 1 March 2017.

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.
1 Application Scope
This Standard specifies the contents including mounting, test parameters and test procedure of samples during vibration (sinusoidal) test for electrical installations in ships.
This Standard applies to vibration (sinusoidal) test for electrical installations in ships.

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. […]
