This standard specifies the quality levels, quality requirements, inspection and test methods and sampling assessment methods for small and medium-sized hydraulic turbine products. This standard applies to mixed-flow, axial-flow, bucket-type and inclined-flow turbines with a power equal to or less than 10 MW (for tubular flow, please refer to the axial flow) and their matching butterfly valves, ball valves and other products. This standard is the basis for assessing product quality, product grading, enterprise upgrading and product excellence. Products are divided into three grades: qualified products, first-class products, and superior products based on quality and performance.
