The manufacturer shall always retain the overall control and shall have the necessary means to take responsibility for the product. NOTE The assignment of tasks to the notified bodies and the manufacturer is shown in Annex ZA, Table ZA.3.1, ZA.3.2 and ZA.3.3. 6.2 Type Testing 6.2.1 General All performances related to characteristics included in this standard shall be determined when the manufacturer intends to declare the respective performances unless the standard gives provisions for declaring them without performing tests. (e.g. use of previously existing data, CWFT and conventionally accepted performance). Assessment previously performed in accordance with the provisions of this standard, may be taken into account provided that they were made to the same or a more rigorous test method, under the same AVCP system on the same product or products of similar design, construction and functionality, such that the results are applicable to the product in question. NOTE Same AVCP system means testing by an independent third party, under the responsibility of a notified product certification body. For the purposes of assessment, the manufacturer's products may be grouped into families, where it is considered that the results for one or more characteristics from any one product within the family are representative for those same characteristics for all products within that same family. Products may be grouped in different families for different characteristics. Reference to the assessment method standards should be made to allow the selection of a suitable representative sample. In addition, the determination of the product type shall be performed for all characteristics included in the standard for which the manufacturer declares the performance (see Table D.1): — at the beginning of the production of a new or modified underlays for walls (unless a member of the same product range), or — at the beginning of a new or modified method of production (where this may affect the stated properties); or — they shall be repeated for the appropriate characteristic(s), whenever a change occurs in the underlays for walls design, in the raw material or in the supplier of the components, or in the method of production (subject to the definition of a family), which would affect significantly one or more of the characteristics.

kSIST FprEN 13859-2:2013
FprEN 13859-2:2013 (E)
 factory production control by the manufacturer, including product assessment.
The manufacturer shall always retain the overall control and shall have the necessary means to take
responsibility for the product.
NOTE The assignment of tasks to the notified bodies and the manufacturer is shown in Annex ZA, Table ZA.3.
6.2 Type Testing
6.2.1 General
All performances related to characteristics included in this standard shall be determined when the
manufacturer intends to declare the respective performances unless the standard gives provisions for
declaring them without performing tests. (e.g. use of previously existing data, CWFT and conventionally
accepted performance).
Assessment previously performed in accordance with the provisions of this standard, may be taken into
account provided that they were made to the same or a more rigorous test method, under the same AVCP
system on the same product or products of similar design, construction and functionality, such that the results
are applicable to the product in question.
NOTE Same AVCP system means testing by an independent third party, under the responsibility of a notified product
certification body.
For the purposes of assessment, the manufacturer's products may be grouped into families, where it is
considered that the results for one or more characteristics from any one product within the family are
representative for those same characteristics for all products within that same family.
Products may be grouped in different families for different characteristics.
Reference to the assessment method standards should be made to allow the selection of a suitable
representative sample.
In addition, the determination of the product type shall be performed for all characteristics included in the
standard for which the manufacturer declares the performance (see Table D.1):
 at the beginning of the production of a new or modified underlays for discontinuous roofing (unless a
member of the same product range), or
 at the beginning of a new or modified method of production (where this may affect the stated properties);
or
 they shall be repeated for the appropriate characteristic(s), whenever a change
