(1) This European Standard applies to concrete for structures cast in situ, precast structures, and structural precast products for buildings and civil engineering structures.

(2) The concrete under this European Standard can be:

- normal-weight, heavy-weight and light-weight;

- mixed on site, ready-mixed or produced in a plant for precast concrete products;

- compacted or self-compacting to retain no appreciable amount of entrapped air other than entrained air.

(3) This standard specifies requirements for:

- the constituents of concrete;

- the properties of fresh and hardened concrete and their verification;

- the limitations for concrete composition;

- the specification of concrete;

- the delivery of fresh concrete;

- the production control procedures;

- the conformity criteria and evaluation of conformity.

(4) Other European Standards for specific products e.g. precast products or for processes within the field of the scope of this standard may require or permit deviations.

(5) Additional or different requirements may be given for specific applications in other European Standards, for example:

- concrete to be used in roads and other trafficked areas (e.g. concrete pavements according to EN 13877–1);

- special technologies (e.g. sprayed concrete according to EN 14487).

(6) Supplementing requirements or different testing procedures may be specified for specific types of concrete and applications, for example:

- concrete for massive structures (e.g. dams);

- dry mixed concrete;

- concrete with a Dmax of 4 mm or less (mortar);

- self-compacting concretes (SCC) containing lightweight or heavy-weight aggregates or fibres;

- concrete with open structure (e. g. pervious concrete for drainage).

(7) This standard does not apply to:

- aerated concrete;

- foamed concrete;

- concrete with density less than 800 kg/m3;

- refractory concrete.

(8) This standard does not cover health and safety requirements for the protection of workers during production and delivery of concrete.

This document describes a method for assessing the performance of photocatalytic inorganic materials contained in cement mortars and/or limes or ceramic-based matrices, paints or materials deposited as thin films or coatings on a variety of substrates for the photocatalytic abatement of nitric oxide in the gas phase. This method is not suitable for the assessment of samples to be applied with flow perpendicular to the surface or flow permeating the surface itself as polymeric and paper filters, honeycomb structures and suchlike.

The performance for the photocatalytic sample under test is evaluated by measuring the degradation rate of nitric oxide (NO) using the method described herein. The photocatalytic abatement rate is calculated from the observed rate by eliminating the effects of mass transfer. The intrinsic photocatalytic abatement rate is an intrinsic property of the material tested and makes it possible to distinguish the photocatalytic activities of various products with an absolute scale defined with physical and engineering meaning.

For the measurements and calculations described in this document the concentration of nitrogen oxides (NOx) is defined as the stoichiometric sum of nitric oxide (NO) and nitrogen dioxide (NO2).

This document provides core product category rules for type III environmental declaration of bituminous materials for building and civil engineering according to EN 13108-1, EN 13108-2, EN 13108-3, EN 13108-4, EN 13108-5, EN 13108-6, EN 13108-7, EN 13108-9, and EN 13108-31. The approach taken for these PCR may be considered applicable and adaptable for other bitumen based products.

This document defines the parameters to be reported, what EPD types (and life cycle stages) to be covered, what rules to be followed in order to generate Life Cycle Inventories (LCI) and conduct Life Cycle Impact Assessment (LCIA) and the data quality to be used in the development of EPDs.

In addition to the common parts of EN 15804, this document for bituminous materials:

— defines the system boundaries;

— defines the modelling and assessment of material-specific characteristics;

— defines allocation procedures for multi-output processes along the production chain;

— includes the rules for calculating the LCI and the LCIA underlying the EPD;

— provides guidance for the determination of the reference service life (RSL);

— gives guidance on the establishment of default scenarios.

Principles used:

— PCR covering bituminous materials;

— from cradle to beyond the building life cycle based on EN 15804;

— polluter pays: processes of waste processing shall be assigned to the product system that generates the waste until the end-of-waste state is reached;

— EPD will be based on declared units (e.g. tonnes of material) and not functional units (e.g. km of road);

— abiotic depletion potential of aggregate should be declared when relevant;

— all use of inert material in the quarry: reclamation, sound and dust protection shall be included in stages A1 to A3 of the EPD;

— data quality will be described (e.g. Average yearly value, average 10 years value, or maximum value ever encountered).

NOTE The Use stage, Informative Module B, depends on the use scenario and this depends on the type of road it is used for, the width of the road, the width of the lane, the total pavement structure and substrate for which pavement layer it is used, the climate conditions, the maximum and minimum pavement temperatures, the traffic intensity and the number of weights of the axle loadings, etc. The use scenario details are determined by the buyer / user of the bituminous mixture. Therefore, only examples on typical maintenance scenarios are given.

This guideline provides PCRs that can be applied for a particular asphalt mixture, from a specific asphalt plant with a specific production temperature. Hence, the design of the asphalt mixture is necessary to produce the specific EPD.

This document outlines requirements for exterior insulation and finish systems (EIFS), used in combination with a drained air space as an exterior wall cladding system. The document includes requirements for a water resistive barrier assembly that are used as part of EIFS.

The EIFS wall cladding system comprises a water resistive barrier assembly, thermal insulation boards, an attachment method to secure the system to the substrate, a glass fibre reinforcing mesh embedded in a base coat on the face of the thermal insulation boards, and a finish coat.

The use of mechanical fasteners is outside the scope of this document which is limited to materials but is addressed in the Part 2: Installation document.

In EIFS, the thermal insulation boards support the base coat with integral glass fibre reinforcing mesh. Systems where the reinforcement is the supporting element of the rendering, e.g. conventional stucco, are not covered by this document.

This document does not purport to address all the health and safety aspects associated with its use. Anyone using this document has the responsibility to establish health and safety practices for it’s use.
