1.3 Standardised output data
Explanations to determine and interpret the specified standardised
output data
1.3.1 Standard: EN 13141-7
The output data specifically mentioned in text, diagrams and
technical datasheets has been determined in line with the test
conditions described in the standard shown in the heading of
this chapter.
Generally, these standardised test conditions will not fully meet
the conditions found at the installation site of the system user.
Depending on the chosen test method and the extent to which
the selected method deviates from the conditions described in the
standard shown in the heading of this chapter, any deviations can
have a considerable impact. Further factors that have an influence
on the test values are the measuring equipment, the system con-
figuration, the age of the system and the flow rates.
A confirmation of the specified output data can only be obtained
if the conditions applicable to the relevant test match those of the
standard shown in the heading of this chapter.
1.4 Units of measurement
Note
All measurements are given in mm unless stated oth-
erwise.
