For the purposes of testing, underlays for discontinuous roofing may be grouped into families where it is considered that the selected property is common to all underlays for discontinuous roofing within that family. 6.2 Initial type testing 6.2.1 General Initial type testing shall be performed to demonstrate the conformity to this document. Tests previously performed in accordance with the provisions of this document (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 underlay 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 4 shall be subject to initial type testing, where relevant (see Table D.1). Whenever a change occurs in the underlay 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 stated 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. 6.2.3 Test results The results of all type tests shall be recorded and held by the manufacturer for a period of at least 5 years. 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 characteristics. The FPC system shall consist of procedures, regular 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 to the requirements of EN ISO 9001, and made specific to the requirements of this document, is considered to satisfy the above requirements. The results of 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.

A.2 Apparatus Tensile testing machine in accordance with EN 12311-1. A.3 Sampling Test samples shall be taken in accordance with EN 13416. A.4 Preparation of test specimens For the purpose of a complete tensile test, two sets of test specimens are to be prepared: one set of five for the longitudinal direction and one set of five for the transverse direction. Test specimens shall be cut from a test piece not closer than 100 mm to the edge of the sheet, with the aid of a template, or die cutter, to provide rectangular test specimens measuring (100,0 ± 0,5) mm wide by a length of at least 200 mm + (2 × gripping length), the longer direction being the test direction. Any non-permanent surface layer or provisional protection sheet shall be removed. Test specimens shall be conditioned for at least 20 h at a temperature of (23 ± 2) °C and relative air humidity in the range 30 % to 70 % before testing. A.5 Procedure The 100 mm wide test specimen shall be folded and joined in the middle as shown in Figure A.1 and tightly clamped in the tensile test machine taking care that the axes of the specimen and grips are correctly aligned. The clear distance between grips shall be (200 ± 1) mm. The test specimen shall be arranged concentrically. A pre-load of maximum 5 N shall be applied before the start of the test to take out any slack in the test specimen. The folded edges shall meet in the middle of the sheet without overlapping. The tolerance of the deviation from the middle shall not exceed ± 1 mm. SIST EN 13859-1:2005+A1:2009
