Adaptor fittings for use with copper tubes may combine short ends for capillary brazing with fitting ends defined in the other parts of EN 1254.
Capillary fittings with short ends for brazing may also have flanged end connections according to EN 1092-3.
Fittings can be produced by machining, metal forming, casting, or fabrication.

This standard establishes the technical safety requirements for :
- constructing ;
- assembling ;
- erecting ;
- operating ;
- servicing ;
of a liquid pump or pump unit. It contains a list of significant hazards, which can arise withthe use of a liquid pump or pump unit, and establishes the requirements and/or measures which will lead to a reduction of the risks. Liquid pumps are described as :
- rotodynamic pumps ; - rotary positive displacement pumps ; - reciprocating displacement pumps ; - supplied separately without driver.
In general, pumps are defined as being terminated by their inlet and outlet connections as well as by their shaft ends. Pump units comprise the liquid pump types above together with a driver (electric motor or i.c.-engine) including transmission elements, baseplates, and any auxiliary equipment. This standard does not deal with the technical safety requirements for the design or manufacture of drivers nor of auxiliary equipment.
