18、 EN 14073-2:2004 (E) 4 1 Scope This document specifies safety requirements for office storage furniture. This document does not apply to high density mechanized filing systems, rotary filing systems or plan files. It should be understood that fulfilling the specified requirements does not ensure tha
19、t failure will not occur as a result of habitual misuse or after an excessively long period of service. Safety depending on structure of the building is not included e.g.: the strength of wall hanging cabinets includes only the cabinet and its parts. The wall and wall attachment are not included. As
20、sessment of ageing is not included. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments)
21、 applies. EN 14073-3:2004 Office furniture - Storage furniture - Part 3: Test methods for the determination of stability and strength of the structure EN 14074:2004 Office furniture Tables and desks and storage furniture - Test methods for the determination of strength and durability of moving parts
22、. 3 Safety Requirements 3.1 Principles Storage furniture shall be designed so as to minimise the risk of injury in normal use. The following safety requirements are based upon the knowledge that office storage furniture and its parts are likely to cause injury only when they are heavy and fall throu
23、gh a significant distance. This is possible if floor standing units overbalance, wall or screen mounted units become detached, or heavy parts become detached from units. Therefore, the test sequence and the safety requirements specified in clause 3.5 and 3.6 are applicable: When the height of the ce
24、ntre of gravity of the unit, or any part is 650mm above the floor and the total mass is 10kg When the potential energy is 65 Nm and the distance from the floor to the lowest edge of the unit or any part is 300mm The potential energy is the multiplication of the total mass of the unit, or the part, a
25、nd the height above the floor in meter (m) to the centre of gravity. EN 14073-2:2004 (E) 5 3.2 Determination of the centre of gravity The centre of gravity of a part or unit shall be taken as the geometric centre of the useable volume of drawers and units, and as the geometric centre of doors, flaps
26、 and shelves. The height of the centre of gravity above the floor shall be measured for units or their parts when installed according to the manufacturers instructions. Floor levelling devices shall be set at their middle position. Storage units that can be positioned at alternative heights shall be
27、 placed in their highest position. All wall or top-mounted units, or parts thereof, are considered to have their centre of gravity more than 650mm above the floor, unless specific restrictions are made by the manufacturer. 3.3 Determination of total mass The total mass is the mass of the part or uni
28、t plus the mass supported by it. Unless conspicuously and durably marked by the manufacturer with a maximum allowable contents load, the mass of the contents shall be determined according to Table 1, which specifies load per unit area for shelves, load per unit volume for extension elements and load
29、 per unit length for clothes rails. The volume of extension elements shall be taken as the area of its bottom multiplied by the clear height. The clear height is the distance between the top of the extension element bottom and the lower edge of the extension element above, or the structure of the un
30、it. Table 1 Loads on storage parts Shelves kg/dm 1,5Clothes rails kg/dm 5,0 Extension elements kg/dm 0,5 Suspended pocket files kg/dm a)4,0 a)Measured perpendicular to the plane of the pocket files. 3.4 General safety requirements Accessible edges and corners shall be free from burrs and rounded or
31、chamfered. There shall be no open ended tubes. All moveable parts accessible during normal use shall have safety distances in any position during movement of 8mm or 25mm. This applies to any two elements moving relatively to each other, with the exception of doors (incl. hinges), flaps (incl. hinges
32、) and extension elements (incl. runners). The safety distances also apply to the distance between handles and other parts. Adjustable parts shall be such as to prevent inadvertent operation or release. If there is a risk of injury, vertically sliding roll fronts shall not close by themselves from an
33、y position higher than 200mm measured from the closed position. Extension elements shall have effective open stops, i.e. they shall resist being pulled out of the carcass once by a horizontal force of 200 N applied to the handle of the loaded extension element.

It is accepted that the safety tests from EN 14073-3 and EN 14074
35、(see the table below) are part of a total test sequence, where all relevant tests according to EN 14073-3 and EN 14074 (also those which are not safety tests) are carried out.
