European foreword

This document (EN 492:2012+A2:2018) has been prepared by Technical Committee CEN/TC 128 “Roof

covering products for discontinuous laying and products for wall cladding”, the secretariat of which is

held by NBN.

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 October 2018, and conflicting national standards shall

be withdrawn at the latest by January 2020.

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. CEN shall not be held responsible for identifying any or all such patent rights.

This document includes Amendment 1, approved by CEN on 24 November 2015 and Amendment 2,

approved by CEN on 9 November 2017.
This document supersedes #EN 492:2012+A1:2016$.

The start and finish of text introduced or altered by amendment is indicated in the text by tags !"

and #$.

This document has been prepared under a mandate given to CEN by the European Commission and the

European Free Trade Association.

For relationship with !EU Regulation No 305/2011", see informative Annex ZA, which is an

integral part of this document.

!In comparison with EN 492:2004, the following sections in EN 492:2012 had been changed or

added:" Clause 2, 3.6, 3.7, 5.1.1, 5.3.3, 5.5.3, 6.3.2, 6.4, 7.3.4.4, 7.3.5.4, 7.5.1.2, 7.5.2.2, Annex A,

Annex D.
Annex ZB concerning the EC Directive 76/769/EEC !had been deleted".

A distinction !had been made" between product appraisal (type tests) and routine quality control

requirements (acceptance tests).

The performance of a roof or another building part constructed with these products depends not only

on the properties of the product as required by this standard, but also on the design, construction and

installation of the components as a whole in relation to the environment and conditions of use.

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, Former Yugoslav Republic of Macedonia,

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
acceptance test

test to establish whether a batch of products conforms to a specification and which is performed on

Note 1 to entry: Test methods and specification limit values are specified in this standard. Sampling levels and

acceptance criteria are given in 6.3.2.
3.2
type test

test carried out to demonstrate conformity with the requirements of this standard or for the approval of

a new product and/or when a fundamental change is made in formulation and/or #manufacturing

process$, the effects of which cannot be predicted on the basis of previous experience

Note 1 to entry: The test is performed on the product as delivered, but is not required for each production

batch.
3.3
acceptable quality level (AQL)

quality level which in a sampling plan corresponds to a specified, relatively high probability of

acceptance

Note 1 to entry: It is the maximum percent defective (or maximum number of defects per 100 units) that for

purposes of sampling inspection can be considered satisfactory as a process average.

Note 2 to entry: A sampling scheme with an AQL of 4 % means that batches containing up to 4 % defective items

have a high probability of acceptance.
3.4
as delivered

same condition as the producer intends to supply the product after completing all aspects of the process

including maturing and, when appropriate, painting
3.5
upper face
face normally exposed to the weather
3.6
under face
reverse of upper face
3.7

fibre-cement slates and fittings of type NT cover products made using a non-asbestos technology

5 Product requirements
5.1 General
5.1.1 Composition

Fibre-cement slates and fittings shall consist essentially of cement or a calcium silicate formed by

chemical reaction of a siliceous and a calcareous material, reinforced by fibres. The cement shall comply

with EN 197-1 or with technical specifications relevant in the country of use.

This European Standard covers fibre-reinforced cement slates and fittings of type NT.

The reinforcing fibres shall take one or more of the following forms:
— discrete elements randomly dispersed,
— continuous strands or tapes,
— nets or webs.

Process aids, fillers and pigments which are compatible with the composite may be added.

5.1.2 Appearance and finish

The exposed face of the fibre-cement slates may be with or without texture. The fibre-cement slates

may be coloured or left in their natural colour. The fibre-cement slates may also receive adherent

coloured or uncoloured coatings on their surface.
The fibre-cement slates may be supplied with holes for fixing.

On exposure, the surface and/or its coating will be affected by weathering which may vary with site

location, aspect, pitch of roof and duration of exposure. Any deterioration in this respect shall not

detract from the minimum mechanical and physical characteristics as specified in this document or

from the function of the fibre-cement slate as a durable element.

The fittings shall have a general appearance and finish compatible with the fibre-cement slates with

which they are to be used. They may be supplied with holes for fixing.
5.2 Dimensions and tolerance
5.2.1 General
The manufacturer shall specify the shapes, sizes and configuration of edges.
NOTE See 5.6 for designation and information.

Fittings shall have nominal dimensions and shapes determined by the manufacturer and appropriate to

the corresponding fibre-cement slates.
5.2.2 Thicknesses

The actual fibre-cement slate thickness determined in accordance with 7.2 shall be not less than that

shown in Table 1.
The nominal thickness shall be specified by the manufacturer.

The nominal thickness of the fittings shall be not less than the corresponding nominal thickness of the

fibre-cement slates with which the fittings are to be used.
---------------------- Page: 10 ----------------------
SIST EN 492:2013+A2:2018
EN 492:2012+A2:2018 (E)
5.2.3 Tolerances on nominal dimensions

The maximum dimensional variation when measured as specified in 7.2 shall be as follows:

— Length and width: ± 3 mm;
+25
— Thickness:
% of the nominal value.
−10

For fittings that replace fibre-cement slates (e.g. ventilation fibre-cement slates) the tolerances shall be

the same as those on the fibre-cement slates.

For other fittings (e.g. ridges) the tolerances shall be specified by the manufacturer.

5.3 Physical requirements and characteristics for fibre-cement slates
5.3.1 General

Mechanical and material properties are determined on products as delivered, wherever practicable. The

results shall be identified as applying to coated or uncoated material.
NOTE See 6.3 for statistical interpretation.
5.3.2 Apparent density

The manufacturer’s literature shall specify the minimum apparent density of the fibre-cement slates.

The fibre-cement slates shall have an apparent density equal to or greater than that specified by the

manufacturer when tested in accordance with 7.3.1.
5.3.3 Mechanical characteristics

When tested in accordance with 7.3.2, the fibre-cement slates shall have a minimum average bending

moment per metre width in newton metres per metre as specified in Table 1.

The minimum bending moment at rupture in the weaker direction shall be not less than 60 % of the

values specified in Table 1 for the average in both directions.

cement slate, but in no instance shall there be any formation of drops
