(informative)
Relationship between this European Standard and the essential
requirements of EU Directive 89/106/EEC, EU Construction Products
Directive
ZA.1 Scope and relevant characteristics
This European Standard has been prepared under the mandate M/100 "Precast Concrete Products" given to
CEN by the European Commission and the European Free Trade Association.
The clauses of this European Standard shown in this annex meet the requirements of the mandate given
under the EU Construction Products Directive (89/106/EEC).
Compliance with these clauses confers a presumption of fitness of the box culvert units covered by this Annex
for the intended uses indicated herein; reference shall be made to the information accompanying the CE
marking.
WARNING — Other requirements and other EU Directives, not affecting the fitness for intended uses, may be
applicable to the box culverts falling within the scope of this standard.
NOTE 1 In addition to any specific clauses relating to dangerous substances contained in this European Standard,
there may be 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
Products Directive, these requirements need also to be complied with, when and where they apply.
NOTE 2 An informative database of European and national provisions on dangerous substances is available at the
Construction web site on EUROPA (accessed through
http://ec.europa.eu/enterprise/construction/internal/dangsub/dangmain_en.htm ).
This annex establishes the conditions for the CE marking of the box culvert units of reinforced concrete used
for the creation of voids below ground for the purposes of conveyance or storage and shows the relevant
clauses applicable.
This annex has the same scope as Clause 1 of this European Standard and is defined by Table ZA.1.

The manufacturer or his authorized representative in the EEA shall select for CE marking the declaration
method(s) he applies among the followings:
Method 1 = declaration of geometrical data and material properties (see ZA.3.2);
Method 2 = declaration of geometry, material properties and product properties determined following this
standard and EN Eurocodes (see ZA.3.3);
Method 3 = declaration of product compliance with a given design specification distinguishing:
Method 3a = declaration of product compliance with a given design specification provided by the client
(ZA.3.4);
Method 3b = declaration of product compliance with a given design specification provided by the manufacturer
according to the client's order (ZA.3.5).
The requirement on a certain characteristic is not applicable in those Member States (MSs) where there are
no regulatory requirements for that characteristic for the intended use of the product. In this case,
manufacturers placing their products on the market of these MSs are not obliged to determine nor to declare
the performance of their products with regard to this characteristic and the option “No performance
determined” (NPD) in the information accompanying the CE marking (see ZA.3) may be used. The NPD
option may not be used, however, where the characteristic is subject to a threshold level.
ZA.2 Procedure(s) for the attestation of conformity of box culvert units
ZA.2.1 Systems of attestation of conformity
The systems of attestation of conformity of the box culvert units, for the essential characteristics indicated in
Table ZA.1, in accordance with the Decision of the Commission 1999/94/EC of 25 January 1999 as given in
Annex III of the Mandate M/100 "Precast concrete products", is shown in Table ZA.2 for the indicated intended
uses and relevant levels or classes:

System 2+: see Directive 89/106 (CPD), 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 (CPD), annex III.2.(ii), Third possibility.
The attestation of conformity of the box culvert units for the essential characteristics indicated in Table ZA.1
shall be based on the evaluation of conformity procedures indicated in Tables ZA.3a and ZA.3b resulting from
application of the clauses of this or other European Standard indicated therein.
