EN 1606:2013 (E) 3 Foreword This document (EN 1606:2013) 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of an identical text or by endorsement, at the latest by September 2013 and conflicting national standards shall be withdrawn at the latest by September 2013. 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 1606:1996.
The revision of this standard contains no major changes, only minor corrections and clarifications of an editorial nature. This European Standard is one of a series of standards which specify test methods for determining dimensions and properties of thermal insulating materials and products. It supports a series of product standards for thermal insulating materials and products which derive from the Council Directive of 21 December 1988 on the approximation of laws, regulations and administrative provisions of the Member States relating to construction products (Directive 89/106/EEC) through the consideration of the essential requirements. This European Standard has been drafted for applications in buildings, but it may also be used in other areas where it is relevant. This European test standard is one of the following group of interrelated standards on test methods for determining dimensions and properties of thermal insulation materials and products, all of which fall within the scope of CEN/TC 88:  EN 822, Thermal insulating products for building applications — Determination of length and width  EN 823, Thermal insulating products for building applications — Determination of thickness  EN 824, Thermal insulating products for building applications — Determination of squareness  EN 825, Thermal insulating products for building applications — Determination of flatness  EN 826, Thermal insulating products for building applications — Determination of compression behaviour  EN 1602, Thermal insulating products for building applications — Determination of the apparent density  EN 1603, Thermal insulating products for building applications — Determination of dimensional stability under constant normal laboratory conditions (23 °C/50 % relative humidity)  EN 1604, Thermal insulating products for building applications — Determination of dimensional stability under specified temperature and humidity conditions  EN 1605, Thermal insulating products for building applications — Determination of deformation under specified compressive load and temperature conditions  EN 1606, Thermal insulating products for building applications — Determination of compressive creep SIST EN 1606:2013

EN 1606:2013 (E) 5 1 Scope This European Standard specifies the equipment and procedures for determining the compressive creep of specimens under various conditions of stress. It is applicable to thermal insulating products. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 826, Thermal insulating products for building applications — Determination of compression behaviour EN 12085, Thermal insulating products for building applications — Determination of linear dimensions of test specimens ISO 5725-2, Accuracy (trueness and precision) of measurement methods and results — Part 2: Basic method for the determination of repeatability and reproducibility of a standard measurement method 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 thickness linear dimension measured perpendicular to the length and width plane, where d
is the original product thickness; dS is the thickness of the specimen; dL
is the thickness of the specimen under the basic compressive stress of the loading device ('dead weight'); d0 is the thickness of the specimen 60 s after the beginning of the loading process; dt is the thickness of the specimen at a given time, t
3.2 compressive stress σc ratio of the compressive force to the initial surface area of the cross section of the specimen 3.3 deformation X reduction in thickness of the specimen 3.4 relative deformation ε ratio of the deformation of the specimen, X, and its thickness dS, measured in the direction of loading SIST EN 1606:2013



EN 1606:2013 (E) 6 3.5 compressive creep Xct increase in deformation of the specimen under a constant stress with time under specified conditions of temperature and humidity Xct = Xt − X0 where Xt is the deformation at time t; X0 is the initial deformation (after 60 s from the beginning of loading) Note 1 to entry: An illustration of the different thicknesses and deformations is given in Figure 1.
Key dL reference value for deformation measurements t time 1 'dead weight' of the loading device (< 10 % of the smallest stress chosen for the creep test) 2 load applied in the compressive creep test 3 deformation curve In this figure, dL is used as a reference value for deformation measurements. If dS is used as the reference value, the figure can be used, omitting the column for dL (see 7.3). Figure 1 — Illustration of the different thicknesses and deformations 4 Principle The compressive creep is determined by measuring the increase in deformation of a specimen under constant compressive stress and specified conditions of temperature, humidity and time.

EN 1606:2013 (E) 7 5 Apparatus 5.1 Loading device, consisting of two flat platens, one of which shall be movable, so arranged that they compress the specimen in a vertical direction.
The movable platen shall be guided in such a manner as to be self-aligning. The platens shall be capable of being loaded smoothly and without distortion so that, during the test, the static stress does not change by more than ± 5 %. 5.2 Measuring device (e.g. dial gauge), capable of determining the distance between the two platens, i.e. the deformation of the specimen, to an accuracy of 0,01 mm. 5.3 Suitable damping measures, to minimise the effects of external vibration (e.g. substantial foundation of the apparatus support). Examples of the testing apparatus are given in Figure 2.

EN 1606:2013 (E) 8 6 Test specimens 6.1 Selection of test specimens The specimens for determining the compressive creep shall be taken from the same sample, with the same preparation as the specimens used for the compression test as specified in EN 826. The method of selecting the specimens shall be as specified in the relevant product standard. In the absence of a product standard or any other European Technical Specification, the method of selection of the test specimens may be agreed between parties. 6.2 Dimensions of test specimens The thickness of specimens shall be equal to the original product thickness. The width of the specimens shall not be less than its thickness. Products with facings or integrally moulded skins which are retained in use shall be tested with these faces or skins intact. Test specimens shall not be layered to produce a greater thickness for testing. The specimens shall be squarely cut and have sides with the following recommended dimensions: 50 mm × 50 mm or 100 mm × 100 mm or 150 mm × 150 mm or 200 mm × 200 mm or 300 mm × 300 mm. The dimensions of specimens shall be the same as used in the compression test as described in EN 826. These are specified in the relevant product standard or agreed between parties. The linear dimensions shall be determined in accordance with EN 12085, to an accuracy of 0,5 %. The tolerance on parallelism and flatness between the upper and lower face of the specimen shall not be greater
