This document specifies the characteristics for external thermal insulation composite kits with a rendering system (ETIC kits) for external walls and/or external finishes of walls (including cladding).

In this document, ETIC kits are used on external walls, which are made either of masonry (bricks, blocks, stones, etc.) or concrete (cast on site or as prefabricated panels).

With regard to the components, this document covers ETIC kits with:

a)     adhesives, which are ready to use mortars, dry mixed mortars or PU adhesive foams, all specified in A.1;

b)    thermal insulations, which are made of one of the following materials: mineral wool (MW), expanded polystyrene (EPS), extruded polystyrene foam (XPS), rigid polyurethane foam (PU), phenolic foam (PF), cellular glass (CG), expanded cork (ICB) or wood fibre (WF), all specified in A.2;

c)     mechanical fixing devices, which are plate anchors, spiral anchors, profiles and rails with collar anchors or anchors for an anchored metal mesh, all specified in A.3;

d)    base coats, which are ready to use or dry mixed, all specified in A.4;

e)     reinforcements, which are glass fibre meshes or metal meshes, all specified in A.5;

f)     key coats, all specified in A.6;

g)     finishing coats, which are ready to use or dry mixed, all specified in A.7;

h)    decorative coats, all specified in A.8.

This document covers ETIC kits, which are fixed to the substrate either with adhesive or mechanical fixing devices or combination of both, clustered as the fixing methods (I to VIII), all defined in to and further specified in A.9.

This document specifies procedures for assessment and verification of constancy of performance (AVCP) of the ETIC kit characteristics.

This document does not cover:

—    ETIC kits with the components and the fixing methods a) other those indicated above and b) not complying with the criteria for their parameters, further specified in Annex A;

—    ETIC kits with other finishing layers than rendering systems, e.g. ceramic tiles, glass tiles, sand-lime-bricks, ceramic brick slips, natural and artificial stones;

—    External insulation and finishing systems (EIFS), according to ISO 17738.

This document specifies the terms, definitions, test conditions, test methods and requirements for rating the performance of air conditioners and liquid chilling packages, with electrically driven compressors and with evaporatively cooled condenser when used for space cooling. The evaporatively cooled condenser is cooled by air and by the evaporation of external additional water. This additional external water is fed by a specific water supply circuit or by a water tank.

This document does not apply to air-to-air and air-to-water air conditioners with a condenser cooled by air and by the evaporation of water condensed on their evaporator.

This document applies to units equipped with a water tank or with a continuous water circuit supply that can also operate without water feeding. However, this document only concerns the testing of these units with water feeding.

This document applies to factory-made units which can be ducted.

This document applies to factory-made units of either fixed capacity or variable capacity by any means.

Packaged units, single split and multisplit systems are covered by this document.

With regard to units consisting of several parts, this document applies only to those designed and supplied as a complete package.

For evaporatively cooled condenser units that can also operate in heating mode, their performance in this mode is determined according to EN 14511 (all parts).

Installations used for industrial processes cooling are not within the scope of this document.

This document specifies the conditions for which performance data will be declared for compliance to the Ecodesign Regulation 206/2012 and to the Energy Labelling Regulation 626/2011 of air conditioners with evaporatively cooled condenser in cooling mode.
