33、ed to the table. They are removable attached if they are removed when the table is closed to the storage position. They are permanently attached if they do not need or cannot be removed when the table is closed to the storage position. For class A net assemblies, the following considerations shall b

34、e relevant: The cross-section of the upright post shall be capable of being circumscribed by a 22 mm square. DIN EN 14468-2:2015-05 EN 14468-2:2015(E)9 Any device for adjusting the height of the net or the tension in a suspending cord shall not project more than 7 mm either from the upright post; or

35、 from the sides or the bottom of the horizontal part of the net supporting post. It is recommended that the height adjustment parts remain in their intended working position and do not fall out. No increase of the length of the horizontal part is acceptable. The structure of the net post shall guara

36、ntee that the net can be suspended exactly at a height of h1= 152,5 mm above the playing surface. The outside limits of the post are 152,5 mm away from the tabletop. It shall be possible to adjust the net height by a minimum of 4,5 mm to h1for classes A and B. The outside limit of the horizontal par

37、t of the net support shall not be more than 160 mm away from the tabletop. The full height of the outside portion of the horizontal part of the net support shall not be more than 80 mm. The horizontal part of the net support shall not project more than 100 mm across the table surface along its net e

38、dge, and not less than 55 mm for non-permanent nets of class A and B. On its full length, the horizontal part of the net support may not be more than 45 mm wide and 15 mm above the elevation of the tabletop surface. In order to allow the mesh of the net getting close to the table surface, there may

39、be a channel in the horizontal part, at least 4 mm wide, and whose bottom shall be not more than 5 mm above the table surface. Permanently attached net posts can be attached to the frame of the tabletop or to the undercarriage or to both. 5.3 Devices for attaching Removable net supports can be attac

40、hed to the playing board by a screw clamp, by a spring clamp or by other suitable means. In any case, the attaching systems shall: a) be easy to attach; b) be firmly attached and resist tension in the net-cord; c) not cause damage to the tabletop; d) for class A, not project more than 100 mm under t

41、he table; e) not be more than 50 mm wide under the table. Any parts of the attaching devices of the net support that are wider than the horizontal part of the net support shall observe the following conditions: f) at least 12 mm under the tabletop surface; g) length less than 100 mm (class A) or 300

42、 mm (classes B to D) at each tabletop; h) be at least 15 mm away from the table side because of shearing. DIN EN 14468-2:2015-05 EN 14468-2:2015 (E) 10 Any other parts of the attaching devices of the net post that are narrower than its horizontal part shall observe both the restrictive dimensions fo

43、r the undercarriage (see EN 14468-1:2015) and for the horizontal part of the net post. 6 Safety requirements If a net post is permanently attached to the table or removable no part of it shall be liable hurt the player or damage the tabletop. If a net post is operated by a spring clamp a safety clea

44、rance of at least 12 mm (h4) shall exist when the clamp is removed from the table. Any change in height, thickness or width of any of the parts of the net posts shall neither be abrupt nor generate sharp or pointed edges or corners. 7 Test methods The requirements of Clauses 5 and 6 shall be appropriately verified, e. g. by measurement, visual inspection, tactile or functional testing.
