1 Scope
This part of GB/T 2820 specifies the test methods to be used for characterizing an entire generating set.
It applies to alternating current (a.c.) generating sets driven by reciprocating internal combustion (RIC) engines for land and marine use, excluding generating sets used on aircraft or to propel land vehicles and locomotives.
For some specific applications (e.g. essential hospital supplies and high-rise buildings), supplementary requirements may be necessary. The provisions of this part may be intended as a basis for establishing any supplementary requirements.
For generating sets driven by other prime movers (e.g. steam engines), this part may be intended as a basis for establishing these requirements.
Note: Existing test methods for engine (GB/T 6072.1-2008 and GB/T 6072.32008) and generator (GB/T 755.2-2003) are applicable for those components. The generating set manufacturer shall be responsible for specifying these characteristics and the tests to be performed to verify them.

3 Other regulations and additional requirements
For a.c. generating sets used on board ships and offshore installations which have to comply with rules of a classification society, the additional requirements of the classification society shall be observed. The classification society name shall be stated by the customer prior to placing the order.
For a.c. generating sets operating in non-classified equipment, any additional requirements must be subject to agreement between the manufacturer and customer.
If special requirements from regulations of any other authority (e.g. inspecting and/or legislative authorities) have to be met, the authority name shall be stated by the customer prior to placing the order.
Any additional requirements shall be subject to agreement between the manufacturer and customer.
