European foreword
This document (prEN 17990:2023) has been prepared by Technical Committee CEN/TC 89 "Thermal
performance of buildings and building components", the secretariat of which is held by SIS.
This document is currently submitted to the CEN Enquiry.
1 Scope
This document specifies methods to determine the durability of bondings, prepared by means of
adhesive materials (e.g. adhesive tapes and adhesive masses), for the establishment of airtight layers
under climatic conditions representative for indoor environments based on test methods with and
without ageing.
The methods provided in this document are neither suitable for a short time evaluation of durability
nor can they be applied to in-field testing.
This document excludes test methods for external weathering or UV exposure, even though this
might occur during the construction phase.
The following typical applications are distinguished:
— bonding of the overlap of flexible airtightness layers;
— bonding of flexible airtightness layers to construction products and penetrations;
— establishment of airtightness layers by means of sheet materials and adhesive tapes.
This document does not cover test methods for:
— pre-compressed sealing tapes and sealing profiles which will be mechanically secured;
— butyl-based adhesive tapes or adhesive masses;
— sheet joints of wood-based panels or gypsum plasterboards with adhesive masses or filler
systems;
— bondings of bitumen membranes or of bitumen membranes to construction products;
— bonding of self-adhesive membranes;
— adhesive masses from reels. Adhesive masses from reels are cured viscoelastic adhesive masses,
which are used in the same field of application as adhesive masses.
The tack is not addressed. It does not allow any conclusion on the durability of a bonding.

layer formed by membranes, boards or other airtight elements installed on the warm side of the
insulation to prevent uncontrolled air movement through the building envelope

functionality of the intended use for a long period of time (service life of construction products or
building constructions) without failure or without failing to meet the minimum requirements of this
standard

viscoelastic adhesive film with or without embedded carrier which is immediately adhesive on both
sides
3.4
single-sided adhesive tape
viscoelastic adhesive film which is immediately adhesive and is covered with a carrier on one side

adhesive mass
non-cured mass which viscoelastically cures due to drying or chemical reaction or which is applied
by melting
Note 1 to entry: Adhesive masses are a subgroup of adhesives according to EN 923.
3.6

Note 1 to entry: The adhesion of the supporting carrier to the adhesive film or adhesive mass has to be
sufficiently strong to allow for the test of the bonding to be examined.

5 Testing
5.1 General
The reference test and the test of product combinations shall be performed with and without
artificial ageing. To full fill the requirements of this document, it is sufficient to perform the tests on
the reference substrates.
The mechanical characteristics of the bonding of two material layers prepared by means of adhesive
tape or adhesive mass is examined before and after artificial ageing. In the course of a test, the
reference case shall be examined.
In addition, a product combination can be optionally tested. In this case, testing is performed
according to 5.2.2. If the substrates of tested product combinations are changed whilst using the
same adhesive material, only the new product combination shall be tested.
The boundary conditions of the test methods in terms of temperature, humidity and duration are
given in Table 2 for adhesive tapes and in Table 3 for adhesive masses.
NOTE Contents regarding conformity assessment are not part of this standard. See DIN 18200 for the
assessment of conformity.
5.2 Test substrate
5.2.1 Reference substrate
In the reference test, the adhesive materials shall be examined on the following substrates:
a) a plastic sheet (a non-sealable, non-deep-drawable and not etched or otherwise pre-treated
biaxially orientated polyester film boPET sheet; see [1]) having a surface tension ≥ 40 mN/m
and a thickness of 50 µm. The surface tension of the plastic sheet shall be determined according
to ISO 8296;
b) beechwood according to EN 205.
NOTE In the following, the abbreviated designations “boPET” and “beech” are used for the reference
substrates.
5.2.2 Product combinations
When testing product combinations, adhesive materials on substrates are examined, for which the
manufacturer of the adhesive material and/or substrate intends to confirm the durability of the
bonding by means of artificial ageing.
