Parts list, drawings and specifications, Solar Keymark Systems

Parts list

For each of the systems of a certification series parts list (bill of materials) must be made available to the inspector / test institute. The parts list shall include all parts of the systems, any changes done to the systems initially tested and the date of revision.

Engineering drawings

Each of the systems of a certification series must be accompanied by a set of engineering drawings of the collectors and storage tanks. The have to be fully dimensioned, including sectional views. Drawings shall have a number, date of issue and possible revision date. The drawings of the collectors have to fulfill the requirements of \"SKN_N0120R0 Annex A\".
