BS EN 12285-3 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. NOTE2 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 non- flammable 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 一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 (subject 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 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 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.
