II SPECIFIC CONDITIONS OF THE EUROPEAN TECHNICAL APPROVAL

1 Definition of product and intended use

1.1. Definition of product

The OPEN JOIST TRIFORCE joists are wood-based composite joists with top and bottom flanges made of solid or finger jointed sawn lumber and web members made of solid sawn lumber with a proprietary grade that meet visual and mechanical requirements listed in the Quality control manual. The top and bottom flanges are connected by a series of diagonal web members, finger joined into the flanges and glued with a resorcinol adhesive type I for structural purpose according to EN 301. The OPEN JOIST TRIFORCE are manufactured with different depths as listed in the relevant Annexes of the present European Technical Approval. The diagonal web members dimensions and arrangement depends on the total length of each joist. One end of the joists is closed by a vertical web member made of solid sawn lumber or glued lumber and the other end by a trimmable OSB part.

1.2. Intended use

The OPEN JOIST TRIFORCE joists are intended to be used as load-bearing parts of building constructions. With regard to moisture behaviour of the product and type of glue, the use is possible in service classes 1 and 2 defined in Eurocode 5. The open web joists are not intended to be used in areas where they might support seismic actions.

The provisions made in this European Technical Approval are based on an assumed intended working life of the joists of 50 years. The indications given on the working life cannot be interpreted as a guarantee given by the producer, but are to be regarded only as a means for choosing the right products in relation to the expected economically reasonable working life of the works.

2 Characteristics of product and methods of verification

The OPEN JOIST TRIFORCE joists in the range covered by this ETA corresponds to the drawings and provisions given in Annex 1. The characteristic material values, dimensions and tolerances of the joists not indicated in Annex 3 shall correspond to the respective values laid down in the technical documentation5 of this European Technical Approval. The mechanical properties of the standard Joists are given in Annexes 3.

Each OPEN JOIST TRIFORCE is marked with the product name (OPEN JOIST TRIFORCE) in capital letters.

2.1. ER 1 Mechanical resistance and stability

The mechanical properties of the standard joists sections are given in Annexes 3. They have been determined on the basis of design assisted by testing except for the characteristic bearing capacity which is calculated according to EN 1995-1-1 . No performance is determined (NPD) towards seismic action.

5 The technical documentation of this European Technical Approval is deposited at the Centre Scientifique

et Technique du Bâtiment and, as far as relevant for the tasks of the approved bodies involved in the attestation of conformity procedure, is handed over to the approved bodies.


2.2. ER 2 Safety in case of fire

No performance determined (NPD) for reaction to fire..

No performance determined (NPD) for resistance to fire.

2.3. ER 3 Hygiene, health and environment

Based on the declaration of the manufacturer, the joists do not contain harmful or dangerous substances as defined in the EU database, with exception of formaldehyde and isocyanate.

In addition to the specific clauses relating to dangerous substances contained in this European Technical Approval, there may be other requirements applicable to the products falling within its scope (e.g. transposed European legislation and national laws, regulations and administrative provisions). In order to meet the provisions of the EU Construction Product Directive, these requirements need also to be complied with, when and where they apply.

2.4. ER 4 Safety in use

Not relevant

2.5. ER 5 Protection against noise

Not relevant

2.6. ER 6 Energy economy and heat retention

The thermal conductivity for the web and flange material is 0,13 W/(m.K) according to EN 12524. The natural density variation of the materials is taken into account in this value.

2.7. Aspects of durability, serviceability and identification

The adhesive is of type I which allows use in service classes 1 and 2. Serviceability of OPEN JOIST TRIFORCE joists is understood as their ability to resist loads without unacceptable deformations.

3 Evaluation of Conformity and CE marking

3.1. Attestation of conformity system

The system of attestation of conformity 2 (i) (referred to as system 1) according to Council Directive 89/106/EEC Annex III laid down by the European Commission provides:

a) tasks for the manufacturer:

1. factory production control, 2. further testing of samples taken at the factory by the manufacturer in accordance

with a prescribed test plan.

b) tasks for the approved body:

3. initial type-testing of the product, 4. initial inspection of factory and of factory production control, 5. continuous surveillance, assessment and approval of factory production control.


3.2. Responsibilities

3.2.1. Tasks of the manufacturer, factory production control

The manufacturer has a factory production control system in the plant and exercises permanent internal control of production. All the elements, requirements and provisions adopted by the manufacturer are documented in a systematic manner in the form of written policies and procedures. This production control system ensures that the product is in conformity with the European Technical Approval.

The manufacturer shall only use raw materials supplied with the relevant inspection documents as laid down in the prescribed test plan6. The incoming components shall be subject to controls and tests by the manufacturer before acceptance.

The manufactured components of the OPEN JOIST TRIFORCE shall be subjected to the following tests:
