(E) 8 1 Scope This European Standard specifies test methods for the determination of properties of composites made from cellulose-based materials and thermoplastics, usually called wood-polymer composites (WPC) or natural fibre composites (NFC). NOTE
For editorial reasons, in EN 15534 the abbreviation “WPC” is used for “composites made from cellulose-based materials and thermoplastics”. This part of EN 15534 is applicable to cellular or non-cellular compounds and products, made from cellulose-based materials and thermoplastics, intended to be or being processed through plastics processing techniques, without threshold for the cellulose-based material content. All the properties listed in this part of EN 15534 are not necessarily assessed for a given application. Test parameters and requirements of the test methods for a given application are specified in the relevant part of EN 15534. Profiles for the management of electrical power cables, communication cables and power track systems used for the distribution of electrical power, profiles for windows or doors and profiles for guttering are not covered by EN 155342). 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

(E) 12 The atmosphere 20/65 (20 °C, 65 % RH) may also be used. In that case, these conditions shall be declared in the test report. Constant mass is considered to be reached when the results of two successive weighing operations, carried out at an interval of 24 h, do not differ by more than 0,1 % (arithmetic mean value) determined on the basis of the mass of the cellulosic material present in the WPC material. If the content of cellulosic material is not known, it shall be determined using a suitable method. If the tested material contains a matrix polymer which itself absorbs water (e.g. starch), the mass of the respective matrix polymer shall be added to the mass of the cellulosic material. If the time until constant mass is reached is considered excessively long, the change in mass of the specimens shall be monitored and recorded over a period of 96 h by taking at least four measurements. Tests are conducted after conditioning for at least 96 h and the moisture content at the time of testing shall be determined according to 6.3 and stated. The content of cellulosic material of the WPC material shall be stated. For each test method, the moisture content of one additional test specimen shall be determined according to 6.3 before testing and shall be declared in the test report. NOTE It is most probable that the moisture equilibrium of the material is not reached but the product is assumed to be suitable for testing. 5.3 Conditioning for factory production control and testing under other conditions For the purpose of factory production control and testing under other conditions, the conditioning shall be carried out according to the specifications defined by the manufacturer. The conditioning parameters and tolerances shall be documented. 5.4 Conditioning for tests performed by third-parties In the case where the tests are performed in a test laboratory of a third party, the tests should be started from the fourth week and not later than the sixth week after the production date of the specimens. The specimens shall be stored under conditions specified in 5.2, except during the transport. 6 Physical properties 6.1 Appearance (applicable to products) The surfaces of the specimens shall illuminated by a source that complies with the CIE standard illuminant D65 (see CIE Publication No. 51) with an illumination of at least 600 lx. The light is incident upon the surfaces at an angle of approximately 45°, and the direction of viewing is approximately along the perpendicular to the plane of the surfaces. 6.2 Density The density of WPC materials shall be determined according to either EN ISO 1183-1 [Method A (immersion method), or Method C (titration method)] or EN ISO 1183-3. For solid profiles, the density of WPC materials may also be determined according to EN 323 [1]. 6.3 Moisture content The moisture content of WPC materials shall be determined according to EN 322:1993 with the following change in 5.2. SIST EN 15534-1:2014+A1:2018

(E) 14 6.4.3.6 Test specimen The test specimen is a surface of at least 1 000 mm in length and 500 mm in width. Components of irregular shape shall be placed on aside the other, as nearby as possible, to cover the test surface of 1 000 mm x 500 mm. The number of test specimens shall be as specified in the reference standard. 6.4.3.7 Test method The test specimen is mounted and centred on the flat plate of the test rig. During the whole test, the test specimen shall be continuously and regularly wetted with a least 5 l/min of the test liquid. If the fugues develop mainly in a specific direction, the specimen shall be tested in this direction and at a 90° angle. The test person moves half the length of a step forwards and backwards in an upright position, looking down to the test specimen surface, in a downstream direction. At the same time, the inclination of the test rig is increased by about 1° per second, starting from a horizontal position. The angle of inclination causing the test person to feel insecure shall be established through repeated changes of the inclination of the rig around the critical value. 6.4.3.8 Evaluation The test results are expressed according to three rating classes: — Class A: 12°: the items with a test result from 12° to 17°; — Class B: 18°: the items with a test result from 18° to 23°; — Class C: 24°: the items with a test result from 24° upwards. 6.4.3.9 Test report The test report shall include the following information: a) a reference to this subclause of EN 15534-1; b) all the information necessary for identification of the product tested; c) the angle of inclination and rating group. 6.4.4 Dynamic coefficient of friction The dynamic coefficient of friction on the surfaces of the product shall be determined according to EN 13893. 6.5 Linear mass (applicable to profiles) 6.5.1 Apparatus 6.5.1.1 Balance, with an accuracy of 0,1 g. 6.5.1.2 Rule or measuring tape, with an accuracy of 0,5 mm.

is the mass of the test specimen, expressed in grams; L
is the length of the test specimen, expressed in metres. 6.6 Dimensional characteristics 6.6.1 Conditioning Condition the test specimens before measuring according to 5.2 or, for the purpose of factory production control, according to 5.3. 6.6.2 Thickness, width and length (applicable to profiles, only) The measurements of the thickness and width of a test specimen shall be carried out manually with an accuracy of 0,05 mm and the measurement of the length, with an accuracy of 1 mm. The number of test specimens shall be as specified in the reference standard. 6.6.3
Deviation from straightness (applicable to profiles, only) The test shall be carried out on the whole cross-section of the profile. The length of the test specimen shall be (1 000 ± 5) mm. The number of test specimens shall be as specified in the reference standard. The test specimen shall be tested in flatwise and edgewise positions. Place the test specimen with its concave side on a flat surface. Measure the gap(s) between the test specimen and the flat surface with an appropriate measuring device. Record the maximum value of the gap. SIST EN 15534-1:2014+A1:2018

(E) 16 6.6.4 Cupping Measure the cupping (flatness deviation across the width) of the test specimen by using a bow gauge placed at the position of greatest deformation. Use a bow gauge, the length of which is at minimum the width of the test specimen, graduated to allow a reading to 0,1 mm (see Figure 1).
Key 1 test specimen 2 bow gauge Figure 1 — Bow gauge for measuring cupping Place the test specimen concave side up without restraint on a flat horizontal surface. Place the bow gauge so that the three points (two fixed and one movable) are lightly touching the surface of the test specimen in the area of greatest deformation, and measure the flatness deviation (shown on the dial gauge) to the nearest 0,1 mm. The two fixed points shall be at 5 mm apart from the edges of the flat surface of the test specimen. The measured point shall correspond to the maximum bow. The measuring tip of the bow gauge shall have a diameter between 10 mm to 16 mm. The maximum flatness deviation measured using the bow gauge shall be recorded. The number of test specimens shall be as specified in the reference standard. 7 Mechanical properties 7.1 Impact resistance 7.1.1 Impact resistance (applicable to compounds) The Charpy impact strength of compound shall be determined according to EN ISO 179-1 by using Method ISO 179-1/1fU.
