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 existing data, CWFT-classifled without further testings and conventionally accepted performance).
Assessments 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.
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 that 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:
at the beginning of the production of a new or modified cut back or fluxed bituminous binder (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 cut back or fluxed bituminous binder design, in the raw material or in the suppher 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 characteflstics.
Where components are used whose characteristics have already been determined, by the component manufacturer, on the basis of assessment methods of other product standards, these characteristics need not be re-assessed. The specifications of these components shall be documented.
Products bearing regulatory marking in accordance with appropriate harmonised European specifications may be presumed to have the performances declared in the DoP, although this does not replace the responsibility on the cut back or fluxed bituminous binder manufacturer to ensure that the cut back or fluxed bituminous binder as a whole is correctly manufactured and its component products have the declared performance values.
A manufacturer may use the results of the product type determination obtained by someone else (e.g. by another manufacturer, as a common service to manufacturers, or by a product developer), to justify his own decLaration of performance regarding a product that is manufactured according to the same design (e.g. same formulation) and with raw materials, constituents and manufacturing methods of the same kind, provided that:
the results are known to be valid for products with the same essential characteristics relevant for the product performance;
— in addition to any information essential for confirming that the product has such same performances related to specific essential characteristics, the other party who has carried out the determination of the product type concerned or has had it carried out, has expressly accepted to transmit to the manufacturer the results and the test report to be used for the latter’s product type determination, as well as information regarding production facilities and the production control process that can be taken into account for FPC;
the manufacturer using other party results accepts to remain responsible for the product having the declared performances and he also:
ensures that the product has the same charactenstics relevant for performance as the one that has been subjected to the determination of the product type, and that there are no significant differences with regard to production facilities and the production control process compared to that used for the product that was subjected to the determination of the product type; and
keeps available a copy of the determination of the product type report that also contains the information needed for verifying that the product is manufactured according to the same design and with raw materials, constituents and manufacturing methods of the same kind.
6.3 Factory production control (FPC)
6.3.1 General
The manufacturer shall establish, document and maintain an FPC system to ensure that the products placed on the market comply with the declared performance of the characteristics.
The FPC system shall consist of procedures, regular inspections and tests and/or assessments and the use of the results to control raw and other incoming materials or components, equipment, the production process and the product.
All the elements, requirements and provisions adopted by the manufacturer shall be documented in a systematic manner in the form of written policies and procedures,
This factory production control system documentation shall ensure a common understanding of the evaluation of the constancy of performance and enable the achievement of the required product performances and the effective operation of the production control system to be checked.BS EN 15322-2013 pdf download.
