1 Scope
This part is applicable to generating sets driven by reciprocating internal combustion engines for emergency power supply to safety services. It applies, for example, to safety services in hospitals, high-rise buildings, public gathering places etc. This part establishes the special requirements for the performance, design and maintenance of generating sets used in the applications referred to above and taking into account the provisions of GB/T 2820.1~2820.6 and GB/T 2820.10.

3 Definitions
For the purposes of this part, the following definitions and those in GB/T 2820.1~2820.6 apply.
3.1
change-over time, tco
time interval from the appearance of a malfunction of the normal electrical power supply system until the safety services are again connected to the emergency power supply; this connection to the safety services may be applied in several load steps
3.2
bridging time, tB
minimum time for which the generating station must supply the consumers with electrical power under pre-determined operating conditions and which corresponds with the rated operating time as defined in IEC 60601
3.3
safety services
equipment for the safety of persons which is installed and kept prepared in case of malfunction of the usual electrical power supply system
3.4
consumer power demand
total of all intended demands of the connected consumers, taking into consideration the actual load steps
3.5
power demand for safety services
required power demand to fulfill the safety service requirements
