Standard Specification for Evaluating Structural Capacities of Rim Board Products and Assemblies
Wood-based panels - Sampling, cutting and inspection - Part 2: Initial type testing and factory production control; German version EN 326-2:2010+A1:2014
This European Standard specifies methods for internal initial type testing (ITT) and internal factory production control (FPC) as well as external control of wood-based panels for their compliance with EN 13986 and other relevant product specifications. However, it may also apply, at the option of the manufacturer, to wood-based panels applied for non-construction purposes. This European Standard is not applicable for the assessment of compliance with specifications of panels comprised in consignments. In such cases, EN 326-3 applies. For internal factory production control, if required, methods for the assessment of conformity of batches and of production over longer periods are given. For external control, if required, methods for the initial inspection of a factory and initial type testing of a product, and for the surveillance of the factory production control, are given. In the factory production control small test pieces are used. The statistics of evaluation is based on normal distribution.

La présente Norme européenne spécifie les méthodes d'essai pour la détermination des propriétés des composites à base de matières cellulosiques et de thermoplastiques, communément appelés composites bois-polymères (WPC) ou composites fibres d'origine naturelle (NFC).La présente partie de l'EN 15534 s'applique aux compositions et produits expansés ou non expansés à base de matières cellulosiques et de thermoplastiques, destinés à être fabriqués ou fabriqués au moyen de techniques de transformation des plastiques, sans seuil pour la teneur en matières cellulosiques.Il n'est pas nécessairement requis pour une application donnée d'évaluer toutes les propriétés
Composites made from cellulose-based materials and thermoplastics (usually called wood-polymer composites (WPC) or natural fibre composites (NFC)) - Part 1 : test methods for characterisation of compounds and products
1.1 This specification recognizes the complexity of structural glued products. Consequently, this specification covers both specific procedures and statements of intent that sampling and analysis must relate to the specific product. 1.2 This specification was developed in the light of currently manufactured products as defined in 3.2. Materials that do not conform to the definitions are beyond the scope of this specification. A brief discussion is found in Appendix X2. 1.3 Details of manufacturing procedures are beyond the scope of this specification. Note 1: There is some potential for manufacturing variables to affect the properties of members that are loaded for sustained periods of time. Users of this specification are advised to consider the commentary on this topic in Appendix X2. 1.4 This specification primarily considers end use in dry service conditions, such as with most protected framing members, where the average equilibrium moisture content for solid-sawn lumber is less than 168201;%. The conditioning environment of 6.3 is considered representative of such uses. 1.5 The performance of structural composite lumber is affected by wood species, wood element size and shape, and adhesive and production parameters. Therefore, products produced by each individual manufacturer shall be evaluated to determine their product properties, regardless of the similarity in characteristics to products produced by other manufacturers. Where a manufacturer produces product in more than one facility, each production facility shall be evaluated independently. For additional production facilities, any revisions to the full qualification program in accordance with this specification shall be approved by the independent qualifying agency. 1.6 This specification is intended to provide manufacturers, regulatory agencies, and end users with a means to evaluate a composite lumber product intended for use as a structural material. 1.7 This specification covers initial qualification sampling, mechanical and physical tests, analysis, and design value assignments. Requirements for a quality-control program and cumulative evaluations are included to ensure maintenance of allowable design values for the product. 1.8 This specification, or parts thereof, shall be applicable to structural composite lumber portions of manufactured structural components. 1.9 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.10 This standard does not purport to addres......
