20、 BS EN 16121:2013EN 16121:2013 (E) 5 1 Scope This European Standard specifies requirements for the safety, strength, durability and stability for all types of non-domestic storage furniture. It does not apply to domestic storage, office storage, industrial storage, kitchen, catering equipment, retai
21、l storage, laboratory storage and industrial storage lockers. Requirements for strength and durability do not apply to the structure of the building for example the strength of wall hanging cabinets includes only the cabinets and the parts used for attachment. The wall and the wall attachments are n
22、ot included. It does not include requirements for the resistance to ageing, degradation and flammability. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

Key 1 structure of the unit 2 clear height H 3 extension element Figure 1 Clear height BS EN 16121:2013EN 16121:2013 (E) 7 3.7 levelling device adjustable device intended to keep the item of furniture perpendicular to the floor Note 1 to entry: Adj
31、ustable feet or similar. 3.8 tray storage element that is designed, under normal use, to be removed from the storage unit and used independently 3.9 potential energy Nm multiplication of the total mass (kg) of the unit (or the part), gravity (m/s2) and the height (m) above the floor to the centre of
32、 gravity Note 1 to entry: For the purpose of this standard gravity can be considered to be 10 m/s2. 4 Test sequence and tolerances 4.1 Individual units When a single unit is supplied for test all the safety tests (5) shall be carried out on the same sample and in the order in which they are listed i
33、n this standard. Tests for strength and durability (6) may be carried out on a second sample. 4.2 Range of units For a range of units featuring similar construction and sharing hardware, or single units with features utilising identical hardware and fixings (e.g. a unit with different size drawers),
34、 selected tests shall be carried out on the worst case units/components as detailed in Annex B. The tests shall be carried out in the order in which they are listed in this standard. If one unit or component within a range of products does not satisfy the requirements of this standard then complianc
35、e for the full range cannot be claimed. 4.3 Tolerances Unless otherwise stated, the following tolerances are applicable: Forces: 5 % of the nominal force; Forces may be replaced by masses. The relationship 10 N = 1 kg may be used. Velocities: 5 % of the nominal velocity; Masses: 1 % of the nominal m
36、ass; Dimensions: 1 mm of the nominal dimension; Angles: 2oof the nominal angle. NOTE For the purposes of uncertainty measurement, test results are not considered to be adversely affected when the above tolerances are met. BS EN 16121:2013EN 16121:2013 (E) 8 5 Safety requirements 5.1 Principles of sa
37、fety requirements 5.1.1 General Safety requirements are based upon the knowledge that storage furniture and its parts are likely to cause injury only when they are heavy and fall through a significant distance. This is possible if floor standing units overbalance, wall or screen mounted units become
38、 detached, or heavy parts become detached from units. Therefore, the tests contained in Table 4 are only considered to affect safety when: the height of the centre of gravity of the unit, or any part, is 650 mm above the floor and the total mass is 10 kg, or when the potential energy (3.9) of the un
39、it, or any part, is 65 Nm and the height of the centre of gravity of the unit, or any part, is 650 mm. 5.1.2 Determination of centre of gravity The centre of gravity of a component or unit shall be taken as the geometric centre of that unit, except in the case of extension elements, where the geomet
40、ric centre of the usable volume shall be used. The height of the centre of gravity above the floor shall be measured for storage furniture or their components when installed according to the manufacturers instructions. Levelling devices shall be set at their middle position. Height adjustable compon
41、ents shall be placed in their highest position. All wall or top hanging units, or components thereof, are considered to have their centre of gravity more than 650 mm above the floor. 5.1.3 Determination of total mass The total mass is the mass of the component or unit plus the mass supported by it.
42、Unless the component is conspicuously and durably marked by the manufacturer with a maximum load, the mass of the contents shall be determined according to Table 1, which specifies mass per unit area for shelves and the mass per unit volume for extension elements, baskets and trays, etc. The volume
43、of fixed baskets and trays shall be taken as the volume contained below their top edge. The volume of extension elements shall be taken as the area of its bottom multiplied by the clear height (3.6). Table 1 Load to determine total mass and load applied to all components other than those undergoing
44、test, excluding stability tests Part Unit Load Horizontal surfaces, tops, shelves, door baskets, etc. kg/dm21,5 Extension elements, trays and baskets kg/dm30,2 Suspended pocket files kg/dm a4 Clothes rails kg/dm 4 aMeasured perpendicular to the plane of the pocket files.

45、3 (E) 9 5.2 General safety requirements The storage units shall be so designed as to minimise the risk of injury to the user. All parts of the storage unit with which the user comes into contact, during intended use, shall be so designed that physical injury and damage are avoided. This requirement
46、is met when: a) the accessible parts are rounded or chamfered, and all other edges accessible during intended use are free from burrs and sharp edges; b) feet of tubular components shall be capped or otherwise closed; c) open ends of tubular components, accessible during intended use, shall be cappe
47、d or otherwise closed. Movable and adjustable parts shall be designed so that injuries and inadvertent operation are avoided. It shall not be possible for any load bearing part of the storage unit to come loose unintentionally. All parts which are lubricated to assist sliding shall be designed to pr
48、otect users from lubricant stains when in normal use. If it can cause injury, all roll fronts and doors sliding vertically including those constructed from hinged elements shall not move by themselves from any position higher than 200 mm measured from the closed position. In order to avoid pinching
49、points for feet, the safe height for vertically moving units shall be at least 100 mm from the floor. Subject to the conditions contained within the general safety principles (5.1.1), all extension elements and trays shall not become detached from the unit when subjected to one horizontal pull force of 200 N applied to the handle of the loaded extension element/tray. The extension element/tray shall be loaded in accordance with Table 1, unless the component is conspicuously and durably marked by the manufacturer with a
