CEN-CENELEC Guide 36:2020 (E)
European foreword
This document (CEN-CENELEC Guide 36:2020) has been prepared by CEN-CENELEC BT WG 9 ‘Strategy for the
construction sector’.
This document is intended for use by Technical Committees drafting candidate harmonized European Standards in
the Construction Sector.
It gives the rules for the presentation of standards for construction products drafted following a standardization
request issued in the framework of Regulation (EU) 305/2011 (CPR).
Other EU Directives/Regulations may also apply to construction products.

CEN-CENELEC Guide 36:2020 (E)
Introduction
CEN-CENELEC is involved in the preparation of candidate harmonized European Standards for construction
products replying to European Commission standardization requests.
It has been considered necessary to propose rules for the preparation, drafting and presentation of candidate
harmonized European Standards for construction products.
Reference should also be made to the CEN Construction web site, which lists many other guidance documents
relevant for the drafting work, accessible at:
https://www.cen.eu/work/Sectors/Construction/Pages/JIS5.aspx
Other instructions and clarifications including a list of FAQs can be found on the European Commission website at:

CEN-CENELEC Guide 36:2020 (E)
1 Scope
This Guide sets out the rules for the drafting and presentation of candidate harmonized European Standards (hENs)
for construction products drafted in the framework of Regulation (EU) 305/2011 (Construction Products Regulation).
This Guide gives rules which are additional to the CEN-CENELEC Internal Regulations — Part 3 (based on ISO/IEC
Directives, Part 2) when this is necessary because of the special provisions of harmonized product standards in the
construction sector.
This Guide applies to all new candidate hENs and for new Work Items (WIs) revising/amending existent hENs.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content constitutes
requirements of this document. For dated references, only the edition cited applies. For undated references, the
latest edition of the referenced document (including any amendments) applies.
CEN-CENELEC Internal Regulations — Part 3:2019, Principles and rules for the structure and drafting of CEN and
CENELEC documents (ISO/IEC Directives — Part 2:2018, modified)

for Annex ZA
NOTE Guidance documents can be found in the following link: https://www.cen.eu/work/Sectors/Construction/Pages/JIS5.aspx
3 General principles
This Guide gives the framework to be followed by Technical Committees (TCs) for drafting of a candidate hEN in the
framework of the Construction Products Regulation (CPR).
Part 3 of the CEN-CENELEC Internal Regulations shall be used in conjunction with this document when preparing a
new candidate hEN, or when revising/amending an existing harmonized European Standard for construction
products as stated in the scope of this document.
For each clause of the candidate hENs to be drafted, a number of examples regarding their content are given.
4 Format of a harmonized European Standard for construction products
4.1 Cover page of the candidate hEN
The cover page of a candidate hEN is prepared by CEN-CENELEC Management Centre (CCMC). However, each
concerned TC shall decide the title of the candidate hEN which shall be appropriate to its contents.
4.2 Element “Title”
The title page shall be prepared according to Clause 11 of CEN-CENELEC Internal Regulations — Part 3:2019.
The proposed title should not be different from the one given in the standardization request (if available) or TC
answer to the mandate prepared by the TC and accepted by the European Commission.
4.3 Element “table of contents”
A “Table of contents” is necessary to make the consultation of the candidate hEN easier.
Clause 6 of CEN-CENELEC Internal Regulations — Part 3:2019 provides guidance on the Organization and
subdivision of the standard.
Terms in the ”Terms and definitions” clause shall not be listed in the table of contents.
CEN-CENELEC Guide 36:2020 (E)
The following lists provides the framework on which a candidate hEN for construction products should be based:

EXAMPLE
This document (EN 450-1:2013) has been prepared by Technical Committee CEN/TC 104 “Concrete and related products”, the
secretariat of which is held by DIN.

This European Standard shall be given the status of a national standard, either by publication of an identical text or by
endorsement, at the latest by February 2015, and conflicting national standards shall be withdrawn at the latest by February
2015.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or
CENELEC] shall not be held responsible for identifying any or all such patent rights.

This document supersedes EN 450-1:2012.

This document has been prepared under a standardization request given to CEN/CENELEC by the European Commission and
the European Free Trade Association.

For relationship with EU Regulation, see informative Annex ZA, which is an integral part of this document.

The main changes with respect to the previous edition are listed below:
- extension of the permissible content of solid co-combustion materials;
- extension of the permissible content of liquid and gaseous co-combustion materials;
- fixed limits for loss on ignition;
- general editorial revision.
According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound
to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland,
France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland,
Portugal, Republic of North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United
Kingdom.
4.5 Element “Introduction”
The introduction, if needed, shall be prepared according to Clause 13 of CEN-CENELEC Internal Regulations —
Part 3:2019,
4.6 Clause 1 “Scope”
Following Clause 14 in the IR - Part 3:2019, this is required at the beginning of every candidate hEN, to define the
subject of the standard and the aspect(s) covered in an unambiguous way and thereby to indicate the limits of
applicability of the standard or particular parts of it.
The scope shall be specific and shall state clearly which product(s), component(s), material(s), form(s), kits (as
relevant) are covered, and for which intended use(s), and which are excluded. If later clauses of the candidate hEN
limit its scope, these exclusions are to be given under the clause “Scope”.
The scope shall be unambiguous and any user shall be able to know, without uncertainty, what is covered and what
is not. The scope shall be at least in accordance with the standardization request(s) (if available) or accepted TC
answer to the relevant mandate. .
Phrases to be avoided are such as “This standard covers products intended generally for external use” or “This
standard covers products made mainly from material X”. In the first example, the user cannot know whether internal
CEN-CENELEC Guide 36:2020 (E)
uses are also covered while, in the second example, the standard would not be based on the performance
approach.
In general and thereby in conformity with Clause 14 in IR – Part 3:2019, the clause “Scope” shall clearly identify the
intended use of the construction product but shall not contain any normative instructions or product characteristics.
Acceptable text could be, for example “These pipes are intended to be used in underground unpressurised sewers”.
Text to be avoided is, for example “These plastic pipes may be used with metal pipes provided that appropriate
joints are provided”; this does not belong to the Scope.
The scope should also, where appropriate, indicate:
 either the location within the works where the construction product is intended to be used (e.g. internal walls,
external walls) or should differentiate between different locations. The relevant construction product
characteristics may well depend on the location in the work;
 whether recycled materials (other than closed-loop recycling during production) are either covered or
excluded, and appropriate provisions should then be included in the body of the standard.
When a hEN is revised, the scope cannot exclude any of the products previously covered, unless:
 they are covered by another standard to be progressed in parallel;
 or excluded by an amendment of the mandate (at least for the harmonized part).

4.7 Clause 2 “Normative references”
The normative references, shall be prepared according to Clause 15 of CEN-CENELEC Internal Regulations — Part
3:2019.
ENs specifying product characteristics for a product shall not contain normative references to quality management
system requirements (e.g. EN ISO 9001, ISO 14000 or related series standards) or certification provisions.
TCs should be aware that it is necessary to provide a technical justification on the use of undated normative
references and this should be provided in a supporting document.
NOTE At the moment the EC considers that all normative references shall be dated. However, it should be noted the common
understanding between CEN and CENELEC, that both dated and undated references can be used in the harmonized European
Standards.
4.8 Clause 3 ”Terms, definitions, symbols, units and abbreviated terms”
As far as applicable, Clause 3 shall cover terms, definitions, symbols units and abbreviated terms and has to be in
accordance with CEN-CENELEC Internal Regulations — Part 3:2019, Clauses 16 and 17. Depending on the actual
content of Clause 3 its title needs to be adapted and sub-clauses shall be introduced.
One standard should contain the definitions used by the other standards, which then make reference back to this
standard. If it is necessary to repeat definitions, they should be copied word by word from whichever document is
considered the reference.
Only definitions used later in the text need to be included.
Definitions may be given:
 in the form of one normative reference to another ISO,IEC,CEN or CENELEC standard dealing with definitions,
symbols and abbreviations relating to this field;
 as a list of specialist terms included in the standard. This should make clear that the definitions are limited to the
use of the terms in the standard.
CEN-CENELEC Guide 36:2020 (E)
Definitions shall not include product characteristics. Any restriction leading to the exclusion of certain construction
products shall be included in Clause 1 “Scope”.
Care should be taken to use terms consistently and to give each term a single meaning. In particular, the terms:
parts or works, element, product, kit, unit, material and component have specific meaning and should not be used
interchangeably, even if this leads to a word being often repeated.
The use in the body of the candidate hEN of symbols or abbreviations that have not been included in this clause,
shall be avoided.
When necessary to use, terms and definitions, which have been defined in the CPR, those terms and definitions
shall be used in the candidate hEN with the same meaning.

4.9 Clause 4 “Characteristics”
All the characteristics of the construction products shall be included in this clause, whether related to standardization
request or not.
NOTE At the moment, the EC considers that all characteristics in the framework of the Basic Work Requirements need to be
included in the hEN (including Annex ZA). However, as long as they are not included in the Standardization Request they cannot
be included in the Annex ZA. CCMC and EC will provide ad-hoc guidance
