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.
NOTE 2 Products can 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 the first workshop fabricated horizontal cylindrical single skin and/or double skin steel tank of a certain class for the underground storage of flammable and nonflammable water polluting liquids (unless a member of the same product range);
— 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 Workshop fabricated horizontal cylindrical single skin and double skin steel tanks for the underground storage of flammable and non-flammable water polluting liquids design, in the raw material or in the supplier of the components, or in the method of production (suhect to the definition of a family), which would affect significantly one or more of the characteristics.
Where components are used whose characteristics have already been determined by the coniponent 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 harmonized European specifications may be presumed to have the performances declared in the DoP, although this does not replace the responsibility on the workshop fabricated horizontal cylindrical single skin and double skin steel tanks for the underground storage of flammable and non-flammable water polluting liquids manufacturer to ensure that the Workshop fabricated horizontal cylindrical single skin and double skin steel tanks for the underground storage of flammable and non-flammable water polluting liquids as a whole is correctly manufactured and its component products have the declared performance values.
6.2.2 Test samples, testing and compliance criteria
The number of samples of workshop fabricated horizontal cylindrical single skin and double skin steel tanks for the underground storage of flammable and non-flammable water polluting liquids to be tested/assessed shall be in accordance with Table.9
The results of the determination of the product type shall be documented in test reports. All test reports shall be retained by the manufacturer for at least 10 years after the last date of production of the Workshop fabricated horizontal cylindrical single skin and double skin steel tanks for the underground storage of flammable and non-flammable water polluting liquids to which they relate.
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 essential 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. Factory production control, therefore, brings together operational techniques and all measures allowing maintenance and control of the compliance of the product with the declared performances of the essential characteristics.
6.3.2 Requirements
6.3.2.1 General
The manufacturer is responsible for organizing the effective implementation of the FPC system in line with the content of this document. Tasks and responsibilities In the production control organization shall be documented and this documentation shall be kept up-to-date.
The responsibility, authority and the relationship between personnel that manages, performs or verifies work affecting product constancy, shall be defined. This applies in particular to personnel that need to initiate actions preventing product non-constancies from occurring, actions in case olnon-constancies and to identify and register product constancy problems.
Personnel performing work affecting the constancy of performance of the product shall be competent on the basis of appropriate education, training, skills and experience for which records shall be maintained.
In each factory, the manufacturer may delegate the action to a person having the necessary authority to:BS/EN 12285-3-2019 pdf download.
