4 Principles
4.1 General principles
Extended application is the outcome of a process (involving the application of defined rules that
may incorporate calculation procedures) that predicts, for a variation of a product property
and/or its intended end use application(s), a test result on the basis of one or more test results
to the same standard.
The extended application of the lightweight partition shall be based on the reference fire test
results performed according to EN 1364-1. Extended application reports shall be prepared
according to EN 15725.
When performing extended applications for a tested partition changes can occur either in
materials and/or in the construction. Both are dealt with in this standard. Table 1 gives an
overview of the changes which may be made in accordance with this extended application
standard.

4.2 Use of test evidence
4.2.1 General
The applicant for the extended application shall either be the “owner” (i.e. sponsor) of the
reference test and additional test evidence being submitted for the extension, or have written
permission from the owner to use the submitted test evidence.
4.2.2 Use of additional test evidence
Additional test evidence may be used to support extended application, for instance to evaluate
the influence of a particular component.
5 General rules
5.1 Fire performance classification
In the extended application, an increase in the classification time (e.g. from 30 min to 45 min)
shall not be permitted.
5.2 Combination of modifications
A combination of modifications mentioned in Table 1 is allowed.
5.3 Reference test
5.3.1 General
The basis for any extension is the reference test.
In case of an extended application described in Clause 6, the reference test shall have an
overrun time and/or a deflection less than the maximum allowed deflection if mentioned in the
relevant clause.
5.3.2 Overrun time
For some extended applications an overrun time is required. The required overrun time
depends on the intended classification time as shown in Table 2 below.
Table 2 — Required overrun time
Classification time Overrun time required
min
≤ 30 ≥ 3 min
> 30 and ≤ 60 ≥ 6 min
> 60 ≥ 10 % of the classification time
5.3.3 Maximum deflection
The maximum deflection of the lightweight partition is not in excess of h/30 with h being the
height of the tested lightweight partition.
