Description: grouping of components based on their construction features; Name: construction type (coupling)
Description: A group of components with the same construction features and the same structure, which - due to similar manufacturing techniques - can be collated for construction approval testing and class conformity controls. They are generally allocated to a construction type. Note: in certain cases, components can be viewed from various construction type specifications as belonging to the same type and, therefore, can be collated for construction approval and class conformity controls; Name: Construction form of the coupling
Description: amount of the absolute value of the total head above the head, equivalent to the vapour pressure of the liquid at the particular temperature, with reference to the NPSH datum plane; Name: net positive suction head
