Trang 61 Scope
This European Standard specifies test methods for horizontal and vertical glass used in furniture It applies to both flat and curved glass
The test methods can be applied to furniture in all fields of application from domestic to contract use
The test methods are designed to represent forces caused by impacts with parts of the human body
The test methods do not apply to glass shelves nor to glass supported over its entire area, including wall fixed mirrors
The standard does not apply to testing and classification of the glass itself as covered by EN 12600.The standard does not include any requirements
2 Normative references
This European Standard incorporates, by dated or undated reference, provisions from other publications These normative references are cited at the appropriate places in the text and the publications are listed hereafter For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision For undated references, the latest edition of the publication referred to applies (including amendments)
EN ISO 2439, Flexible cellular polymeric materials — Determination of hardness (indentation technique) (ISO
2439:1997, including Technical Corrigendum 1:1998)
ISO 7619, Rubber — Determination of indentation hardness by means of pocket hardness meters
3 General test conditions
3.1 Preliminary preparation
Unless otherwise specified in a requirement document, the following conditions apply:
Before any of the tests are commenced, the item shall be old enough to ensure that it has developed its full strength At least four weeks in normal indoor conditions shall have elapsed between manufacturing (or assembly) and testing in the case of glued joints in timber etc
The furniture shall be tested as delivered If of knockdown type, it shall be assembled according to the instructions supplied with the furniture If the furniture can be assembled or combined in different ways, the most adverse combination shall be used for each test The same is valid for units that can be combined with other units or components
The tests shall be carried out in indoor conditions, but if during a test the temperature is outside the range of 15° C
to 25° C, the maximum and/or minimum temperature shall be recorded in the test report
Tighten all assembly fittings before testing
3.2 Tolerances
Unless otherwise stated, the following tolerances apply:
- Masses: ± 0,5 % of the nominal mass;

- Dimensions: ± 1,0 mm of the nominal dimension;
- Angles: ± 2° of the nominal angle
4 Test equipment
4.1 Floor surface
The floor surface shall be a rigid, horizontal and flat surface
4.2 Wall surface
The wall surface shall be a rigid, vertical and flat surface
4.3 Stops
To prevent the sample from sliding, stops shall not be higher than 12 mm except in cases where the design of the sample necessitates the use of higher stops, in which case the lowest stop that will prevent the sample from sliding shall be used
4.4 Impact hammer for vertical glass (see Figure 1)
A cylindrical pendulum head, assembly (1 + 2 + 3) in Figure 1, with a mass of (6,5 ± 0,07) kg, supported from a pivot by a cold drawn seamless steel tube of 38 mm in diameter and with a wall thickness of 2 mm (4 in Figure 1) The mass of the steel tube shall be (2 ± 0,2) kg The distance between the pivot and the centre of gravity of the pendulum head shall be 1 m A low friction bearing shall pivot the pendulum arm

4.5.1 Circular body
The circular body shall be 200 mm in diameter, separated from the striking surface by helical compression springs and free to move relative to it on a line perpendicular to the plane of the central area of the striking surface The body and associated parts minus the springs shall have a mass of (17 ± 0,1) kg and the whole apparatus, including mass, springs and striking surface, shall have a mass of (25 ± 0,1) kg
4.5.2 Springs
Springs shall be such that the combined spring system has a nominal spring rate of (6,9 ± 1) N/mm and the total friction resistance of the moving parts is between 0,25 N and 0,45 N
The spring system shall be compressed to an initial load of (1040 ± 5) N (measured statically) and the amount of spring compression movement available from the initial compression point to the point where the springs become fully closed, shall be not less than 60 mm

4.5.3 Striking surface
The striking surface shall be a rigid circular object, 200 mm in diameter, the face of which has a convex spherical curvature of 300 mm radius with a 12 mm front edge radius
4.6 Polyurethane foam sheet
The polyether foam sheet shall have a thickness of 100 mm, a bulk density of (30 ± 2) kg/m3 and an indentation hardness index of (170 ± 20) N according to A 40 of EN ISO 2439, with dimensions approximately 200 mm more than the diameter of the impactor (4.5)

5 Test method for vertical glass
Place the unit on the floor surface (4.1) or on the wall surface (4.2)
The impact point on the glass surface shall be in the vertical plane If necessary, the unit shall be tilted
Face the striking surface of the glass with a 10 mm thick rubber pad (4.7) at the point of impact
With the arm of the impact hammer hanging vertical and the striking surface touching the rubber pad at the impact position specified in the requirement document Position free-standing furniture with stops around the feet and with wall mounted units attached to a test wall

Trang 10
Let the impact hammer (4.4) fall freely through the specified height onto the glass on those positions and for the number of times specified in the requirement document
Carry out the test on the number of test samples specified in the requirement document
Before each impact, check that there are no glass splinters in the rubber pad nor in the rubber of the impact hammer head
Carry out inspection and assessment of test result according to clause 7
6 Test method for horizontal glass
Place the unit on the floor surface (4.1) or on the wall surface (4.2)
The impact point on glass surface shall be in the horizontal plan If necessary, the unit shall be tilted
Place a piece of polyurethane foam (4.6) on the glass surface on a position specified in the requirement document With the impactor resting on the foam, adjust the fall height according to the requirement document
Let the impactor (4.5) fall freely through the specified height onto the glass on those positions and for the number
of times specified in the requirement document
Carry out the test on the number of test samples specified in the requirement document
Before each impact, check that there are no glass splinters in the polyurethane foam or in the striking surface of the impactor
Carry out inspection and assessment of test result according to clause 7
7 Inspection and assessment of test results
After the test, check the glass according to the following:
a) damage to the glass;
b) glass that has become completely dislodged;
c) glass that has been broken by the impactor in one of the following manners:
1) numerous cracks appear forming separate fragments with sharp edges, some of which are large;
2) numerous cracks appear, but fragments hold together and do not separate;
3) disintegration occurs, leading to a number of particles, which are relatively harmless
NOTE Breakage type c)1 is typical of annealed glass Breakage type c)2 is typical of laminated glass Breakage type c)3 is typical of toughened and heat treated glass
The inspection and assessment of test results shall include detailed documentation of any damage to the glass
8 Test report
