Standardised output data

Explanations to determine and interpret the specified standardised
output data
Standard: EN 16147
The output data specifically mentioned in text, diagrams and
technical datasheets has been calculated according to the test
conditions of the standard shown in the heading of this section.
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 this
method deviates from the conditions defined in the norm shown in
the heading of this section, any deviations can have a considerable
impact. Additional factors that have an influence on the test values
are the measuring equipment, the system configuration, 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.
