SPECIFIC PARTS 1. TECHNICAL DESCRIPTION OF THE PRODUCT

The product ECOSISM is a non-load-bearing shuttering kit based on preassembled panels of insulating materials and one storey height, applicable as formwork for plain and reinforced concrete walls cast in-situ, structural and non-structural. The shuttering panels are mechanically inserted into a 3D wire-rod reinforcement cage made of horizontal and vertical electrically welded steel rods of Ø2.2 mm (see Annex A1). The panels are 100 to 1200 mm wide (steps of 100 mm, the last step can be adjusted to 10 mm), 150 to 12000 mm high (steps of 150 mm, the last step can be adjusted to 50 mm), as detailed in Annex A2. The thickness of the outer shuttering panels ranges from 40 to 250 mm whereas the one of the inner shuttering panels ranges from 40 to 100 mm. The concrete infill structural pattern is of continuous type and it can be produced in the thickness range from 80 to 350 mm. Therefore, the total thickness of the shuttering can vary from 170 to 520 mm according to the dimensions of the wire spacers and/or the insulating panels (see Annex A3/1-A3/2). Shuttering panels made of the following basic insulating materials are adopted (as specified in Annex A4):

• Expanded-Polystyrene Syntherized (EPS) • Extruded-Polystyrene Syntherized (XPS) • Mineral wool (MW) • Wood wool (WW) • Phenolic foam (PF) • Factory made rigid polyurethane foam (PU)

The vertical edges of each panel are flat. Prior to pouring concrete, adjacent units are wired together, vertically plumbed and propped on one side. The props are kept in place until the concrete has reached the initial design strength. No special elements are used for making joints, window and door openings, which are obtained by inserting (or not) shuttering elements into the 3D steel cage (see Annexes A5-A6-A7). Finally, after concrete has cured, the metal wire rods inside the openings, doors and windows, shall be removed. Renderings, coatings and plasters are not part of this ETA. 2. SPECIFICATION OF THE INTENDED USE IN ACCORDANCE WITH ETAG 009 USED AS

EUROPEAN ASSESSMENT DOCUMENT (hereinafter EAD)

The product ECOSISM is intended to be used as formwork for plain and reinforced concrete walls cast in-situ, load-bearing or non-load-bearing , internal and external, above or below ground, including those which are subject to fire regulation. The load-bearing concrete walls obtained with the kit are not covered by this ETA and they are subject to the applicable national regulation, under the direct responsibility of the designer. Concerning product packaging, transport and storage it is the responsibility of the manufacturer to undertake the appropriate measures and to advise his clients on the transport and storage, as he considers necessary in order to reach the declared performances. The information about installation is provided with the technical documentation from the Manufacturer and it is assumed that the product will be installed according to it or (in absence of such instructions) according to the usual practice of the building professionals. The performances assessed in this European Technical Assessment, according to the applicable EAD, are based on an assumed intended working life of at least 50 years, provided that the conditions for the installation, packaging, transport, storage, installation as well as appropriate use, maintenance and repair are met. The indications given on the working life cannot be interpreted as a guarantee given by the manufacturer, 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.

3. PERFORMANCE OF THE PRODUCT AND REFERENCES TO THE METHODS USED FOR ITS ASSESSMENT

The performance assessment of the product ECOSISM were carried out in compliance with ETAG 009 used as EAD according to the test methods reported herein, as well for what concerns sampling, conditioning and testing provisions.

3.1 MECHANICAL RESISTANCE AND STABILITY (BWR 1)

# Essential characteristic Performance

1 Type of structural pattern The type of structural pattern is continuous

2 Efficiency of filling See Annex B1

3 Possibility of inserting the steel reinforcement By examining technical drawings, the possibility of inserting at least the minimum required steel reinforcement for reinforced concrete walls is verified. The additional spacers provide suitable cover as wall as they efficiently hold the reinforcement in place.

Such results are confirmed by the on-site practice tests carried out in the conditions given in Annex B1.

3.2 SAFETY IN CASE OF FIRE (BWR 2)

# Essential characteristic Performance

4 Reaction to fire See Annex B2

5 Resistance to fire See Annex B2

3.3 HYGIENE, HEALTH AND THE ENVIRONMENT (BWR 3)

# Essential characteristic Performance

6 Dangerous substances NPA(1)

7 Water vapour permeability See Annex B3

8 Water absorption EPS: based on the results of the on-site inspection carried out in the conditions given in Annex B1, it is observed that water absorption by the shuttering in contact with fresh concrete is negligible so that it is drained out again during the evaporation period.

3.4 SAFETY AND ACCESSIBILITY IN USE (BWR 4)

# Essential characteristic Performance

10 Bond strength and resistance to impact load Not applicable, since no finish is incorporated in the shuttering kit.

11 Resistance to filling pressure Resistance to filling pressure is assessed by both calculations and on-site practice tests on the complete shuttering systems carried out in the conditions given in Annex B1.

During the on-site tests, the shuttering kits showed adequate resistance to filling pressure under the most extreme filling conditions specified by the manufacturer with no cracks nor failure in the current position and at junctions, and no significant irreversible bowing was observed (maximum deflection value lower than 5 mm).

Adequate resistance to filling pressure has been confirmed also by the calculation results.

The obtained results are valid for all the adopted basic insulating materials.

12 Safety against personal injuries Delivered on site, the shuttering kit has sharp points.

19 Resistance to normal use damages Normal use impacts

Not applicable, since no finish is incorporated in the shuttering kit.

Incorporation of the ducts

The integrity of any of the kit components is provided by the voids for horizontal passing ducts made on site; the diameter of the voids shall coincide with the diameter of the ducts; the ducts must be installed in the voids before filling in with concrete. Detailed instructions are given in the installation guide of the manufacturer.

Fixing of objects

As resulted from eccentric vertical loads tests according to §7.2 of the ISO DIS 8413, it is possible to fix the objects up to 100 kg mass with eccentricity of 30 cm from the external surface of the wall by means of 4 plastic fixing devices Ø 12 mm and 70 mm long in the finishes of the shuttering leaves (coating based on 3 cm-thick cement-lime mortar).

For other cases the fixing devices should be inserted in the concrete.

Note:

A European reference fire scenario has not been laid down for façade. In some Member States, the classification

use in façades. An additional assessment of the system according to the National provisions (i.e. based on a

large-scale test) might be necessary to comply with specific Member State Regulations, until the existing
