EN 14909:2012 (E) 5 Introduction The purpose of damp proof courses is to prevent water rising up a wall from the ground, water moving from one part of a wall to another and to deflect water from an inner wall of a cavity wall construction to the exterior of the building. Damp proof courses may also be used in masonry chimneys and parapet walls to protect the inside of the building from water moving down from above. They should be designed in conjunction with flashings and sheets for waterproofing, including roofing sheets and damp proof sheets, to ensure a continuous barrier and should deflect water to the exterior of a building so that it can drain away safely.

According to EN ISO 11925-2, the test is required to be undertaken on the exposed surface of the delivered flexible sheet membrane (surface exposure) free hanging without any substrate in one direction only, and the reinforcement has to be stated by the manufacturer as “organic” or “inorganic”. a) Test results from EN ISO 11925-2 for a given product shall apply to all colors (including black, white). b) Test results from EN ISO 11925-2 for a given product without an inner layer (homogenous) shall apply to a comparable product with an additional organic inner layer (lower than 150g/m2) or any additional inorganic layer. c) Test results from EN ISO 11925-2 for a product with a thickness of above 1 mm shall apply to any comparable product with a higher thickness up to a limit of 3 mm respectively d) Test results from EN ISO 11925-2 for a given product with a backing shall apply to a comparable product with a backing of the same type of lower mass per unit area or no backing. NOTE It is currently considered that the Euroclasses Classification system at Classes D and above requires investigation to determine its appropriateness to the products covered by this European Standard (the SBI test may be inappropriate for products covered by the standard). Pending results of such an investigation and discussions in the Fire Regulators Group, products covered by this European Standard are tested to EN ISO 11925-2. If and when a new fire test scenario and test method are developed for the products, this European Standard will be amended to refer to them. 5.16 Dangerous substances NOTE For products placed on the market within the European Economic Area, see ZA.1.

Materials used in products shall not release any dangerous substances in excess of the maximum permitted levels specified in a relevant European Standard for the material or permitted in the national regulations of the member state of destination. 6 Evaluation of conformity 6.1 General The compliance of the product with the requirements of this European Standard and with the stated values (including classes) shall be demonstrated by:  initial type testing,  factory production control by the manufacturer, including product assessment. For the purposes of testing, products may be grouped into families, where it is considered that the results for a given characteristic from any one product within the family are representative for all other products within that family. 6.2 Initial type testing 6.2.1 General Initial type testing shall be performed to show conformity with this European Standard. Tests previously performed in accordance with the provisions of this European Standard (same product, same characteristic(s), SIST EN 14909:2012

EN 14909:2012 (E) 11 test method, sampling procedure, system of attestation of conformity, etc.) may be taken into account. In addition, initial type testing shall be performed at the beginning of the production of a new product type (unless a member of the same family) or at the beginning of a new method of production (where this may affect the stated properties). All characteristics in Clause 5 shall be subject to initial type testing, where required, see Table 1. Whenever a change occurs in the product design, the raw material or supplier of the components, or the production process (subject to the definition of a family), which would change significantly one or more of the characteristics, the type tests shall be repeated for the appropriate characteristic(s). The results of all initial type tests shall be held by the manufacturer for a period of at least ten years after the date of last production of the products to which they relate.

The minimum number of tests to show compliance for initial type testing shall be one for all characteristics, unless a given test method specifies otherwise. 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 conform to the stated performance 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. An FPC system conforming with the requirements of EN ISO 9001, and made specific to the requirements of this standard, is considered to satisfy the above requirements. The results of inspections, tests or assessments requiring action shall be recorded, as shall any action taken. The action to be taken when control values or criteria are not met, shall be recorded. 6.3.2 Frequency of testing The characteristics to be controlled within the framework of factory production control are those for which the manufacturer claims a performance. Control of the product is required, either by direct testing or by indirect control. The frequency of testing shall be given in the manufacturer's FPC system.
