Precast normal/lightweight/autoclaved aerated concrete products (1):
Intended for light structural(2) or non-structural use (in particular, boundary fences, junction boxes for telecommunications, small box culverts, non-loadbearing wall elements and cladding elements).
Precast normal/lightweight/autoclaved aerated concrete products:
Intended for structural use (in particular prestressed hollow core floor elements, posts and masts(3), foundation piles, shuttering slabs, lattice girder elements, beam/block floor units and elements, ribbed floor slabs, linear structural elements (beams and columns), load-bearing wall elements, retaining wall elements, roof elements, silos(4), stairs, bridge deck elements and large box culverts).
For the product(s) and intended use(s) listed below, CEN/Cenelec are requested to specify the following system(s) of attestation of conformity in the relevant harmonised standard(s):
| a Light structural use refers to applications that in case of failure are not supposed to cause the collapse of the works or part of them, inadmissible deformations or injury to people (to be defined by Member States). | |||
| System 2 +: See Directive 89/106/EEC, Annex III(2)(ii), First possibility, including certification of the factory production control by an approved body on the basis of initial inspection of factory and of factory production control as well as of continuous surveillance assessment and approval of factory production control. System 4: See Directive 89/106/EEC, Annex III(2)(ii), Third possibility. | |||
| Product(s) | Intended use(s) | Level(s) or class(es) | Attestation of conformity system(s) |
|---|---|---|---|
| Precast normal/lightweight/autoclaved aerated concrete products | for structural use — for non-structural or light structural usea | — — — | 2 + — 4 |
The specification for the system should be such that it can be implemented even where performance does not need to be determined for a certain characteristic, because at least one Member State has no legal requirement at all for such characteristic (see Article 2(1) of Directive 89/106/EEC and, where applicable, point 1.2.3. of the Interpretative Documents). In those cases the verification of such a characteristic must not be imposed on the manufacturer if he does not wish to declare the performance of the product in that respect.
Excluding pipes and tanks.
Light structural use refers to applications that in case of failure are not supposed to cause the collapse of the works or part of them, inadmissible deformations or injury to people (to be defined by Member States).
Excluding lighting columns on highways.
Excluding the storage of liquids.
