EN 16837:2018 (E) 3 European foreword This document (EN 16837:2018) has been prepared by Technical Committee CEN/TC 217 “Surfaces for sports areas”, the secretariat of which is held by AFNOR. 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of an identical text or by endorsement, at the latest by October 2018, and conflicting national standards shall be withdrawn at the latest by October 2018. 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. According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

EN 16837:2018 (E) 4 1 Scope This European Standard specifies a test method for the determination of shoe/surface friction of synthetic sports surfaces. The method can be used for the assessment of both indoor and outdoor sports surfaces. NOTE This method is not considered suitable for long pile synthetic turf surfaces. 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. ISO 48, Rubber, vulcanized or thermoplastic — Determination of hardness (hardness between 10 IRHD and 100 IRHD) ISO 4662, Rubber, vulcanized or thermoplastic — Determination of rebound resilience ISO 7619-2, Rubber, vulcanized or thermoplastic — Determination of indentation hardness — Part 2: IRHD pocket meter method 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 slip resistance property of the surface which limits the relative movement between the contact patch of footwear (slip) and the sports surface 3.2 friction resistance to relative motion between two bodies in contact 3.3 vertical load vertical force exerted on the sports surface by the test foot 3.4 linear shoe/surface friction property measured which is expressed as Pendulum Test Value (PTV) 4 Principle The Pendulum Tester incorporates a spring-loaded slider (test foot) made of a standard rubber attached to the end of a pendulum. On releasing the pendulum from a horizontal position, the loss of energy as the test foot passes over the test surface is measured by the reduction in length of the upswing using a calibrated scale. 5 Apparatus and materials The pendulum test shall incorporate the essential features given below and as illustrated in Figure 1. All bearings and working parts shall be enclosed as far as possible, and all materials used shall be treated to prevent corrosion under wet conditions. SIST EN 16837:2018

EN 16837:2018 (E) 6 5.1 A spring-loaded slider, assembled as specified in 5.8.
It shall be mounted on the end of a pendulum arm so that the sliding edge is (514 ± 6) mm from the axis of rotation. 5.2 A pendulum arm.
The mass, including the test foot, shall be (1,50 ± 0,03) kg. The centre of gravity shall be on the axis of the arm at a distance of (410 ± 5) mm from the axis of rotation. 5.3 Means for setting the support column of the equipment as vertical. 5.4 A base of sufficient mass to ensure the equipment remains stable during the test. 5.5 Means of raising and lowering the axis of suspension of the pendulum arm so that the slider can swing clear of the surface of the specimen, and be set to traverse a surface over a fixed length of (126 ± 1) mm.
A gauge as shown in Figure 2 shall be suitable. SIST EN 16837:2018

The mass of the pointer shall be not more than 85 g. 5.8 A circular scale (C scale) as described in Table A.1 and Figure A.1, calibrated for a nominal sliding length of 126 mm on a flat surface marked from 0 to 150 at intervals of five.

EN 16837:2018 (E) 8 Tests in this mode of operation give the Pendulum Test value (PTV) directly. 5.9 The wide test foot (see Figure 3) shall consist of a slider rubber (76,2 ± 0,5) mm wide, (25,4 ± 1,0) mm long (in the direction of swing) and (6,35 ± 0,5) mm thick with an aluminium backing.
The combined mass of test foot shall be (32 ± 5) g.

This is the 0 reading. 6.2 The slider rubber The slider rubber shall be vulcanized or bonded onto the backing. The test foot shall be provided with a central pivoting axis which shall be mounted on the end of the pendulum arm in such a way that, when the arm is at the lowest point of its swing with the trailing edge of the slider rubber in contact with the test surface, the plane of the slider is angled at (26 ± 3)° to the horizontal. In this configuration the slider can turn about its axis without obstruction to follow the unevenness of the test surface as the pendu
