Scope

This standard specifies the type and model, technical requirements, scope of supply and spare parts, technical documents, inspection and acceptance, nameplate, packaging, transportation and storage, installation, operation and maintenance of small water turbines. This standard is applicable to turbines with a unit power of 500kW~10000kW (excluding 10000kW) and a runner diameter less than 3.3 m. Water turbines with unit power below 500kW can be implemented as a reference.
