17、goals. This standard is applicable to goals for training and competition intended to be used for outdoor hockey. Goals intended to be used for indoor hockey see EN 749. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated referen

21、 of the crossbar is in line with the rules of the International Hockey Federation.6 Net 7 Rear backboard 8 Upright 9 Bottom back bar Figure 1 Hockey goal type 2 One hockey goal consists of: the goal frame (2 uprights and 1 crossbar) including net fixings (and ground sockets for type 1); the backboar
22、ds (1 rear backboard, 2 side backboards); 2 net supporting brackets; 2 bottom side bars; anti-tilting devices (at least one at each side) (for type 2); 1 bottom back bar; 1 net. 3.3 Material The goal frame and the backboards may be made of timber, steel, light metal or plastic material, provided the
23、 requirements of this document are fulfilled. Net supporting brackets and bottom side and back bars shall be made of light metal and/or steel protected against corrosion (e.g. hot galvanized, powder coated or painted). EN 750:2004 (E) 6 For the net, net yarns made of synthetic or natural fibres may
24、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 test-ing according to 5.2. The go
25、al frame should be either white or the natural silver colour of light metal. NOTE White colour is in line with the International Hockey Federation. 3.4.2 Nets 3.4.2.1 Dimensions The net dimensions shall comply with Table 2.

28、For the ground socket see informative Annex A of EN 749:2004. When using sockets out of doors, they shall have a drainage hole. 4 Safety requirements 4.1 General Corners and edges which may cause injuries, shall be rounded with a radius of at least 3 mm. 4.2 Goal frame The edges of the goal frame sh
29、all be rounded to a radius of (3 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. 4.4 Stability When tested in accordance with 5.3, the goal shall not tilt nor slide. 4.5 Net supporting brackets The
30、connection of net supporting brackets shall not protrude outside the goal frame. 4.6 Net fixings 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 th
31、e cross bar) are 8 mm or 25 mm. Metal cup hooks shall not be used. If spring hooks 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
32、 angle of less than 60 and no openings of less than 230 mm diameter. The net shall be suspended loosely so that a ball thrown into the goal cannot rebound from the constructional parts. The net shall be fixed so that the ball will not pass between the goal frame and the net or between the back board
33、 and the net. The cross section of the side parts shall not protrude past the uprights. EN 750:2004 (E) 8 5 Test methods 5.1 General If not otherwise specified in the following requirements of Clauses 3 and 4 are tested by measuring, visual inspec-tion or practical test. Execute the test after condi
34、tioning the goal for a minimum of 1 h at a test temperature of (20 5) C. 5.2 Determination of strength Apply a vertical 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 aft
35、er removal of the force. 5.3 Determination of stability Install the goal in its normal position of use. Apply a horizontal 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 2). Note any falling over or sliding. 6 Assembly,
36、installation and maintenance instructions The manufacturer shall provide written instructions for assembly, installation 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. EN 750:2004 (E) 9

38、duct and check periodically afterwards; At all times the goal shall be secured against tilting; Never 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 7501); b)
39、 the name or trademark of the manufacturer, retailer or importer and 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. 1)Marking EN 750 on or in relation to a product represents the manufacturer
40、s declaration of conformity, i.e. a claim by or on behalf of the manufacturer that the product meets the requirements of the standard. The accuracy of the claim is therefore solely the responsibility of the person making the claim. Such a declaration should not be confused with third party certifica
