Testing in accordance with 7.2. 5.3.3 Colour of playing surface Classes A, B: Preferably green or blue, of any degree of darkness having a Y-value under illuminant D651) of not more than 30 % (CIE system). The colour of lines for Classes A and B shall be white. Classes C, D: Optional. 5.3.4 Degree of gloss and regularity The playing surface including the lines shall be matt.

With the exception of the 4 corners of the full tabletop all the other edges shall be blunt. For Class A any side protection of the playing board shall have a maximum thickness of 1 mm. NOTE The residual hazard of the 4 corners of the tabletop is an unavoidable feature of the design of the table. 5.3.6.2 Frame reinforcements The height of the frame reinforcement plus the top may be no more than 100 mm (see Figure 7). The thickness of the lower frame shall be ≥ 3 mm and the edge of the frame has to be rounded with a radius of min. 1 mm. The frame of Class A shall be flush with the side edge of the tabletop. 5.3.7 Area for attaching a net assembly If the table is not supplied with a permanent net assembly a gap is needed between the frames of the two tabletops as shown in Figure 10.

If a Type 2 table Class A is moved on castor wheels, the minimum distance of the tabletop to the floor shall be 50 mm. NOTE This last requirement is included for the protection of the feet of the operators. 5.4.2.3 Swivelling For each undercarriage with four wheels, at least two shall swivel. For each undercarriage with three wheels not inline, at least one shall swivel. If a table Type 2 has one wheel, or two or more wheels inline they shall not swivel. 5.4.3 Climatic stresses on locking devices for outdoor tables The locking devices shall be made of materials that are resistant to corrosion and light exposure. 5.5 Horizontal deviation The table shall be so stable that during the test in accordance with 7.6 the horizontal deviation measured on the surface of the table in the direction of the force does not exceed SIST EN 14468-1:2015

EN 14468-1:2015 (E) 20 — for Class A: 10 mm, — for Class B: 20 mm, — for Class C: 40 mm. Tables of Class D shall not collapse. 5.6 Residual height reduction After completion of the loading test in 7.7.1 and after allowing 5 min ± 15 s for recovery, the height of the corners of the table halves (net and end) of classes A, B, C and D tables shall not be reduced by more than the value shown in Table 5. Table 5 — Maximum permitted residual height reduction after unloading Dimensions in millimetre Class Residual height reduction A and B 5 C 10 D 15 5.7 Unfolding of a tabletop of a rollaway table Legs that are intended to extend during the folding down of a raised tabletop shall extend automatically, without needing to be pulled forwards. 5.8 Additional requirements and recommendations for tables for wheelchair play Type 2 and Type 3 tables are normally not intended for use by wheelchair players. To allow access to wheelchairs, the table legs shall be set back not less than l3 from the table end (see Table 3). Below the height of h3 space of not less than l12 shall be kept free of any obstacles in order to accommodate the athlete's feet (see Table 3). NOTE The residual obstacle presented by the legs of the table is considered to be an unavoidable and acceptable design feature. For wheelchair table tennis, h6 is recommended to be a maximum of 80 mm (see 5.3.6.2) in the player's safety area.
