European foreword

This document (EN 16809-1:2019) has been prepared by Technical Committee CEN/TC 88 “Thermal insulating

materials and 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text or by endorsement, at the latest by May 2020, and conflicting national standards shall be withdrawn at the

latest by August 2021.

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.

EN 16809-1, Thermal insulation products for buildings — In situ formed products from loose-fill expanded

polystyrene (EPS) beads and bonded expanded polystyrene beads, consists of two parts which form a package.

The first part (this document), covers the products, which are placed on the market. The second part covers the

specification for the installed products. Both parts need to be used for the application of the insulation product

in the end-use applications covered by EN 16809-2.

The reduction in energy used and emissions produced during the installed life of insulation products exceeds

by far the energy used and emissions made during the production and disposal processes.

According to the CEN-CENELEC Internal Regulations, the national standards organisations 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.

Rules for mounting and fixing when testing are given in Annex D and EN 15715.
6 Designation code

The manufacturer shall give a designation code for the product. The following shall be included except when

there is no requirement for a property described in 4.3:
— In situ formed EPS beads EPS
— This document number EN 16809-1
— Settlement class (only for loose-fill beads products) Si
— Water absorption WS
— Water vapour diffusion resistance factor MUi
where “i” shall be used to indicate the relevant class or level.

The designation code for a loose-fill expanded polystyrene product is illustrated by the following example:

EXAMPLE EPS EN 16809-1 – S1 – WS – MU1
7 Assessment and verification of the constancy of performance
7.1 General

The manufacturer or his authorized representative shall be responsible for the conformity of his product with

the requirements of this document. The verification of the constancy of performance shall be carried out in

accordance with EN 13172 and shall be based on product type determination (PTD) and factory production

control (FPC) by the manufacturer, including product assessment and tests on samples taken at the factory.

The compliance of the product with the requirements of this document and with the stated values (including

levels and classes) shall be demonstrated by:
— Product type determination (PTD);
— Factory production control by the manufacturer, including product assessment.

If a manufacturer decides to group his products, it shall be done in accordance with EN 13172.

7.2 Product type determination

All characteristics defined in 4.2 and those in 4.3 if declared shall be subject to product type determination

(PTD), in accordance with Annex B of this document.
7.3 Factory production control

The minimum frequencies of tests in the factory production control shall be in accordance with Annex B of this

document. When indirect testing is used, the correlation to direct testing shall be established in accordance

with EN 13172.
8 Marking and labelling

Products conforming to this document shall be clearly marked, either on the label on the packaging or on the

delivery note, with the following information:
— product name or other identifying characteristic;

— the intended use of the expanded polystyrene for insulation of buildings is given by the abbreviation ThlB;

— name and address of the manufacturer or identifying mark or his authorized representative;

— shift or time of production or traceability code;

— reaction to fire class (RtF) of the product as placed on the market in accordance with 4.2.5

If reaction to fire tests on standardized assemblies have been performed according to EN 15715:2009, Clause 6,

then the reaction to fire classification shall be added and identified with the designation “Standardised

assembly no. x” after the classification.

The number of the standardized assembly is taken from EN 15715:2009, Table 5. Reference to manufacturer's

literature (ML) for further information.
— declared thermal conductivity;
— designation code as given in Clause 6;
— delivery quantity of material.

Determination of the declared values of thermal resistance and thermal
conductivity
A.1 Introduction

It is the responsibility of the manufacturer to determine the declared value of thermal resistance and thermal

conductivity. He will have to demonstrate conformity of the product to its declared value. The declared value of

thermal resistance and thermal conductivity of a product are the expected value of the property during an

economically reasonable working life under normal conditions, assessed through measured data at reference

conditions.
A.2 Input data

The manufacturer shall have at least ten test results for thermal resistance and thermal conductivity, obtained

from external direct or from internal direct measurements in order to calculate the declared values. The direct

thermal resistance and thermal conductivity measurements shall be carried out at regular intervals spread over

a period of the last twelve months. If less than ten direct test results are available, that period may be extended

until ten test results are reached, but with a maximum period of three years, within w
