Overview

FprEN 14782 - "Self-supporting metal sheet for roofing, external cladding and internal lining - Product specification and requirements" (CEN) defines the terminology, product requirements and test methods for factory-made, self-supporting metal sheets and tiles intended for non‑structural roofing, wall cladding and internal lining. The standard covers self-supporting copper, zinc, steel, aluminium and stainless steel sheets, with or without metallic, organic, inorganic or multi‑layer coatings, and includes curved sheets, products used with insulation or membranes, ceilings, soffits and cassettes. It also addresses marking, labelling and conformity assessment but does not include structural design, installation methods, or thermal/acoustic insulation performance.

Key topics

• Scope & terminology: Definitions for base materials, liner trays, cassettes and other product types relevant to factory-made sheets.
• Material and coating requirements: Accepts a range of substrates and coatings (metallic, organic, multi‑layer); Annex A covers multilayer coated steel.
• Dimensional requirements: Nominal thickness, dimensional change and dimensional tolerances for manufactured pieces.
• Mechanical resistance: Tests for general mechanical behaviour and specific methods to determine resistance to concentrated forces (see Annex B).
• Water, vapour and air permeability: Requirements and test methods relevant to cladding and lining performance.
• Durability & corrosion testing: Durability criteria and referenced test methods (e.g., salt spray, humidity).
• Fire performance: Rules for external fire exposure classification and reaction to fire testing (EN 13501‑5, EN 13501‑1, EN ISO 11925‑2 and related procedures); Annex C covers mounting/fixing for reaction-to-fire tests.
• Assessment & conformity: Type testing, sampling, Factory Production Control (FPC) and AVCP provisions for CE marking and declaration of performance.
• Marking and designation: Labelling requirements to enable traceability and correct product specification.

Applications and users

FprEN 14782 is applicable to manufacturers, product designers, specifiers, building envelope consultants, fabricators and quality assessors working with metal roofing, external cladding, internal metal lining, soffits and cassette systems. Typical uses:

• Architectural roofing and façade panels for non‑structural applications
• Pre‑formed cassettes and soffit linings
• Lined systems incorporating insulation and membranes (non‑structural)

Specifiers use the standard to verify product conformity, test regimes and labelling; manufacturers use it to set production control and testing programs.

Related standards

Key referenced standards include EN 506, EN 508‑1/2/3 (product specs for specific metals), EN 13501‑1/5 (fire classification), EN ISO 11925‑2 (ignitability), EN ISO 9227 (salt spray), EN ISO 6270‑1 (humidity) and EN ISO 6892‑1 (tensile testing). These provide the detailed test methods and supplementary requirements referenced by FprEN 14782.

C-s3,d0 without further testing in accordance with the EU Decision 2010/737/EU.
5.2.3 Other products
Products not complying with the provisions of 5.2.1 or 5.2.2 shall be tested and classified in accordance with
EN 13501-1.
When testing in accordance with EN 13823 (SBI test), the product shall be mounted according to Annex C.
6 Assessment and verification of constancy of performance - AVCP
6.1 General
The compliance of the products covered by this draft European Standard with the requirements of this draft
standard and with the performances declared by the manufacturer shall be demonstrated by:
— determination of the product type;
— factory production control by the manufacturer, including product assessment.
The manufacturer shall always retain the overall control and shall have the necessary means to take
responisibility for the conformity of the product with its declared performances.
6.2 Type testing
6.2.1 General
Type testing shall be performed to show conformity with this draft standard.
oSIST prEN 14782:2015
prEN 14782:2015 (E)
Tests or assessments previously performed in accordance with the provisions of this draft standard (same
product, same characteristic(s), test method, sampling procedure, system of attestation of conformity, etc.) may
be taken into account to reduce the number of checks. In addition, type testing shall be performed at the
beginning of the production of a new product type (unless a member of the same family) or at the beginning of a
new method of production (where this may affect the stated properties) on the profile machine and/or the
product itself.
Where the finished product manufacturer buys a base material whose characteristics have already been
determined in accordance with the provisions of this draft standard and are declared by the base material
supplier (e.g. following an inspection document conforming to EN 10204), these characteristics need not be
reassessed in order to demonstrate conformity with this draft standard, provided that the production process for
the finished product does not change these characteristics in an unfavourable way. ITT for the characteristics of
the finished product related to the characteristics of the base material itself is given in Table 2 and may be
assessed either by the base material supplier or the roofing/cladding product manufacturer. ITT for the other
product characteristics is given in Table 3.
NOTE The profile process can increase locally the yield strength of the metal. Where the manufacturer uses this fact to
claim a higher yield strength for the finished product, a type test will be required.
For the purposes of assessment, the manufacturer’s products may be grouped into families, where it is
considered that the results for one or more characteristics from any product within the family are representative
for that same characteristics for all products within that same family
Products may be grouped in different families for different characteristics.
In addition, the determination of the product type shall be performed for all characteristics included in the draft
standard for which the manufacturer declares the performance:
— at the beginning of the production of a new or modified self-supporting metal sheet for roofing, external
cladding and internal lining (unless a member of the same product range), or
— at the beginning of a new or modified method of production (where this may affect the stated properties); or
they shall be repeated for the appropriate characteristic(s), whenever a change occurs in the self-supporting
metal sheet for roofing, external cladding and internal lining design, in the raw material or in the supplier of the
components, or in the method of production(subject to the definition of a family), which would affect significantly
one or more of the characterisitcs.
The base material may be presumed to have the performances stated of them by their supplier, although this
does not replace the responsibility on the finished product manufacturer to ensure that only a base material
having the correct values of characteristics to allow the finished roofing or cladding product to meet the
requirements of this draft standard are used.
All characteristics in Clause 4 shall be subject to type testing, with the following exceptions:
— external fire performance when using the CWFT option, in accordance with 5.1.2 or when deemed to
satisfy, in accordance with 5.1.1 (although measurement may be required to ensure that the product meets
the definitions required for CWFT and deemed to satisfy),
— reaction to fire when using the CWFT option (although measurement may be required to ensure that the
product meets the definition required for CWFT), in accordance with 5.2.2, or when deemed to satisfy
Class A1, in accordance with 5.2.1,
— release of regulated substances may be assessed indirectly by controlling the content of the substance
concerned.
oSIST prEN 14782:2015
prEN 14782:2015 (E)
Whenever a change occurs in the product, the base material or supplier of the components, or the production
process (subject to the definition of a family), which could change significantly one or more of the
characteristics, the type tests shall be repeated for the appropriate characteristic(s).
The results of all type tests shall be recorded and held by the manufacturer for at least 10 years after the end of
production of the product to which they apply.

6.2.2 Sampling for product type determination
The choice of the method of sampling shall be as defined in a) or b) below, as appropriate.
a) Random sampling:
Whenever practicable, the random sampling method shall be used, in which every base material or finished
product of the same type in a delivery batch has an equal chance of being selected for the sample. The
required numbers of specimens shall be selected from a batch at random, without any consideration given
to the condition or quality of the selected specimens.
b) Representative sampling
When random sampling is impracticable, e.g. when the products form a large stack or stacks with ready
access to only a limited number of products, a representative sampling procedure shall be used.
6.3 Factory production control (FPC)
6.3.1 General
The base material manufacturer shall establish, document and maintain a FPC system to ensure that the
products placed on the market conform to the stated performance characteristics. The FPC system shall consist
of procedures, regular inspections and tests and/or assessments and the use of the results to control base
material and other incoming materials or components, equipment, the production process and the product.
If the finished product manufacturer buys base materials whose characteristics have already been determined
in accordance with the provisions of this draft standard, and are declared by the base material supplier (e.g.
following an inspection document conforming to EN 10204), the finished product manufacturer's system
requires only a document check to ensure that the characteristics meet the product manufacturer's
specifications, provided that the production process for the finished product does not change in an unfavourable
way these characteristics.
oSIST prEN 14782:2015
prEN 14782:2015 (E)
Products whose characteristics have not already been determined and finished products, for which the
production process changes characteristics in an unfavourable way, shall be evaluated in accordance with

No testing required for a given profile if the physical dimensions of the product are subject to regular checking.
b
The profile shall be checked directly on the machine at the beginning of each production run and/or new shift. The following
geometrical characteristics shall be checked directly on the machine at the beginning of each run: the height of the ribs, the radius of the
profile, the position of the stiffeners, the distance between two consecutives ribs, the height of stiffeners of any flat part, webs, the width
of the flat part and the cut angle of the sheet do not need to be checked.
c
In the case of a profile machine producing the same profile continuously, a minimum of 2 checks per year shall be made.
d
This checking does not apply to the length of the sheet, the contraction or bulging, the deviation from straightness, the profiled edge
or the ripple of the side lap.
e
No direct testing of these characteristics is needed. However, the manufacturer shall check, with a frequency, to be defined in the
FPC manual, sufficient to ensure that ITT results remain applicable to all products. When using CWFT or deemed-to-satisfy, indirect
checks of product parameters may be needed.
The results of inspections, tests or assessments requiring action shall be recorded, as shall any action taken.
The action to be taken when control values or criteria are not met shall be recorded and retained for the period
specified in the manufacturer’s FPC procedures. The results of all FPC tests shall be recorded and held by the
manufacturer for at least 10 years.
