EN 750-2004 pdf download.Playing field equipment – Hockey goals – Functional and safety requirements , test methods.
This EN 750 specifies the functional requirements for 2 types (see Clause 3) and the safety requirements (see Clause 4) for hockey 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.

3 Requirements
3.1 ClassifIcation
Hockey goals shall be classified by the design (types) as shown in Table 1.
— 1 bottom back bar;
– met.
3.3 Material
The goal frame and the backboards may be made of timber, steel, light metal or plastic material, provided the 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).
5
EN 750:2004 (E)
For the net, net yarns made of synthetic or natural fibres may be used.
3.4 Design
3.4.1 Goalframe
The construction shall be sufficiently secure to withstand the stresses occumng during a game and during transport
The latter requirement is fulfilled when the corner section of the goal frame is not deformed or damaged after testing according to 5,2.
The goal 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.
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 shall be rounded to a radius of (3± 1) mm.
The cross section of the side parts shall not protrude past the uprights.
4.3 Strength
When tested in accordance with 52. 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 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 the cross bar) are c 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 downwards angle of less than 60’ and no openings of less than 230 mm diameter.
5 Test methods
5.1 General
If not otherwise specified in the following requirements of Clauses 3 and 4 are tested by measuring, visual 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 vertical force of 1 800 N at the centre of the crossbar for 1 mm
Note any fracture or other damage to the goal.
Remove the force and measure any permanent deformabon 30 mm * s after 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 mm s by means of a rope of 3 000 mm length (see Figure 2). Note any falling over or sliding.
6 Assembly, installation and maintenance instructions
The manufacturer shall provide written instructions for assembly, installation and maintenance.
It shall be pointed out in the assembly instruchons that any goals that are not being used at the moment should be secured against overturning.EN 750-2004 pdf download.
