Standardised output data
Explanations to determine and interpret
the specified standardised output data
Standard: EN255-3
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 condi-
tions will not fully meet the conditions
found at the installation site of the system
user. Depending on the chosen test meth-
od 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 configuration, the age of the sys-
tem and the flow rates.
A confirmation of the specified output
data can only be obtained if the condi-
tions applicable to the relevant test match
those of the standad shown in the head-
ing of this chapter.
