EN 13967:2004 (E) 9 6 Evaluation of conformity 6.1 General The compliance of a plastic or rubber damp proofing sheet with the requirements of this document 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 selected property is common to all products within that family. 6.2 Type testing 6.2.1 General Initial type testing shall be performed to show conformity with this document. Tests previously performed in accordance with the provisions of this standard (same product, same characteristic(s), 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. 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). 6.2.2 Sampling Samples shall be taken according to EN 13416. The minimum number of tests to show compliance for initial and further type testing shall be one for all characteristics. 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. If a manufacturer claims compliance with FPC requirements by operating an EN ISO 9001 system, EN ISO 9001 shall be applied in full and shall be made specific to the requirements of this document.
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.
EN 13967:2004 (E) 10 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.

Method of measuring the resistance of ventilating and draining damp-proof sheets to deformation under load B.1 Principle This is a method for the determination of the resistance of ventilating or draining thermoplastic damp-proof sheets and water vapour control products to deformation under load. The method is intended for the initial testing and/or for quality control purposes. The purpose of the test is to determine the loading resistance of flexible profiled (non-flat) sheets for damp protection which in addition provide ventilation or drainage to deformation under load. A conditioned test specimen is placed under a fixed load. Deformation is recorded as a function of time. The test is suitable for products, other than flat sheets, which experience plastic creep, i.e. the test measures the ability of the products to retain their shape under a long term fixed load. A suitable fixed load is defined as the required design load, plus a factor of safety. The time period for testing is determined by assessment of the development of deformation with time in relation to both acceptable degree of deformation and expected life of product. These factors are illustrated in Figures B.1 and B.2. Extrapolation shall not exceed one unit of logarithmic time and the extrapolated part of the data shall be clearly indicated by a dotted line. tD10987650510152025303540XXXXXXXXXXXX

Load may be applied by the use of physical weights or an alternative comparable method. Deformation is registered as a function of time. Preloading of the specimen prior to zeroing of deformation instrumentation may be applied to suit the product to be tested. Zeroing of the deformation instrumentation shall be arranged such that any deformation prior to zeroing is either eliminated or negligible. Deformation is preferably measured direct on the pressure plate, or as close to the specimen as is practically possible, so that deformation errors in the apparatus are eliminated. Measuring instruments for deformation shall have a minimum accuracy of ± 0,02 mm. All measurements shall be recorded to the nearest 0,01 mm. NOTE A typical test apparatus using physical weights is shown in Figure B.3.
