A handball goal Type 1 consists of:

24、 the goal frame (2 uprights and 1 crossbar) including net fixings and ground sockets; 1 net with net headline and net weighting. Handball goals Type 1 may also be made with net supporting brackets and bottom back bar like Type 2; other goals can be supplied as a folding up type with a supporting fra

EN 749:2004 (E) 7 3.3 Material The goal frame may be made of timber, steel, light metal or plastics. Net supporting brackets and bottom side and back bars shall b

27、e made of light metal and/or steel protected against corrosion (e.g. hot galvanized, powder coated or painted). The net fixings to the goal shall be made of non-corrosive metal or of plastic material. For the net, net yarns may be used made of synthetic or natural fibres. For the net headline synthe

28、tic ropes shall be used. 3.4 Design 3.4.1 Goal frame The construction shall be sufficiently secure to withstand the stresses occurring during a game and during trans-port. The latter requirement is fulfilled when the corner section of the goal frame is not deformed or damaged after testing according

29、 to 5.2. The uprights and the crossbar should be marked in accordance with the current regulations of the sports associ-ations. 3.4.2 Nets 3.4.2.1 Dimensions The net dimensions shall comply with Table 2.

32、ength suitable for the installation shall be drawn in at the top of the net and fixed so that no dis-placement will be possible (see Figure 1). The breaking force of the net headline shall be at least 7 000 N, see Ta-ble 4. The net shall be suspended loosely so that a ball thrown into the goal canno

33、t rebound from the constructional parts. The fixing devices shall therefore be outside the net. The net shall be retained on the wall by means of the net headline or by means of the net supporting brackets. The net shall be so fixed that the ball will not pass between the goal frame and the net. If

34、an additional net curtain is used, it shall have the same mesh and width as the main net and shall be fixed 3.4.3 Ground sockets When using ground sockets out of doors, they shall have a drainage hole. 4 Safety requirements 4.1 General requirements Corners and edges, which may cause injuries, shall

35、be rounded with a radius of at least 3 mm. 4.2 Goal frame The edges of the goal frame shall be rounded to a radius of (4 1) mm. 4.3 Strength When tested in accordance with 5.2, the crossbar shall not fracture or collapse or show permanent deformation greater than 10 mm. (700100) mm from the front. 0

36、EN 749:2004 (E) 9 4.4 Stability When tested in accordance with 5.3, the goal shall not fall over nor slide. 4.5 Net supporting brackets If net supporting brackets are used, the connection shall not protrude outside the goal frame. 4.6 Net fixings The net shall be loosely attached to the uprights and

37、 the crossbar. Net fixings shall be designed in such a way that the player cannot be hurt. This requirement is fulfilled if e.g. external openings (i.e. on the circumference of the cross section of the uprights and the cross bar) are 8 mm or 25 mm. Metal cup hooks shall not be used. If spring hooks

38、are used as means of fixation or for the end of a rope, they shall have screw caps. 4.7 Frame entrapment Any possible entrapment in the frame above 1200 mm above the ground, e.g. net supports, shall have no down-wards angle of less than 60 and no openings of less than 230 mm diameter. 5 Test methods

39、 5.1 General If not otherwise specified in the following the requirements of Clauses 3 and 4 are tested by measuring, visible inspection or practical test. Execute the test after conditioning the goal for a minimum of 1 h at a test temperature of (20 5) C. 5.2 Determination of strength Apply a verti

40、cal force of 1 800 N at the centre of the crossbar for 1 min100+s. Note any fracture or other damage to the goal. Remove the force and measure any permanent deformation 30 min300+s after removal of the force. 5.3 Determination of stability Install the goal in its normal position of use. Apply a hori

41、zontal force (F) of 1 100 N at the top of the centre of the crossbar for 1 min100+s by means of a rope of 3 000 mm length (see figure 3). Note any falling over or sliding. 6 Assembly, installation and maintenance instruction The manufacturer shall provide written instructions for assembly, installat

42、ion and maintenance. It shall be pointed out in the assembly instructions that any goals that are not being used at the moment should be secured against overturning.

43、l be fixed to the goal with the following wording: This handball goal is designed to be used for handball, indoor football or indoor hockey only and no other pur-pose; Check all fastenings are fully tightened before using this product and check periodically afterwards; At all times the goal shall be

44、 secured against tilting; Do not climb on the net or goal framework. NOTE Also an appropriate graphical symbol may be used. 8 Marking Goals shall be marked with the following information: a) the number of this document EN 7491); b) the name or trademark of the manufacturer, retailer or importer and

45、the year of manufacturing of the frame; c) a warning label giving details of use that the goal is designed for and type of net in accordance with Clause 7. In the case of goals Type 2 there shall be an indication at the sides of the uprights concerning the required fasten-ing of the goal. 1)Marking
