24、016 (E) 5 Introduction With this revision the included test methods have been as far as possible taken out of the standard and referenced to: EN 16122:2012, Domestic and non-domestic storage furniture Test methods for the determination of strength, durability and stability. This standard was prepare

25、d in order to provide assurance that domestic storage furniture and kitchen-worktops comply with the given requirements and are safe. The intention of this European Standard is the prevention of serious injury through normal use, as well as foreseeable misuse. It cannot ensure that structural failur

26、e will not eventually occur as a result of habitual misuse. Co-ordinating sizes for kitchen furniture (including kitchen-worktops) kitchen appliances, sinks and decorative panels are covered by EN 1116, Kitchen furniture Co-ordinating sizes for kitchen furniture and kitchen appliances. BS EN 14749:2

27、016EN 14749:2016 (E) 6 1 Scope This European Standard specifies safety requirements and test methods for all types of kitchen and bathroom storage units and domestic storage furniture and their components. It does not apply to non-domestic storage, office storage, industrial storage, catering equipm

28、ent, retail storage and industrial storage lockers. It does not apply to units covered by EN 71-1, Safety of toys Part 1: Mechanical and physical properties and EN 60065, Audio, video and similar electronic apparatus Safety requirements (IEC 60065). It does not include requirements for the resistanc

29、e to ageing, degradation, flammability and electrical safety. Safety that is dependent upon the structure of the building is not included, e.g. the strength of wall hanging units includes only the cabinet and its components including wall attachment devices. The wall and the wall attachments are not

30、 included. Annex A (normative) contains additional test methods. Annex B (informative) contains a guide to testing of units and components according to this document. Annex C (informative) contains an example of loading of wall hanging units. Annex D (informative) contains a method for calculation o

31、f vertical and horizontal acting forces. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the

32、 referenced document (including any amendments) applies.

44、apply. 4.2 Sequence of testing The tests shall be carried out in the same sequence as the clauses are numbered in this European Standard. 4.3 Tolerances Unless otherwise stated, the following tolerances are applicable: Forces: 5 % of the nominal force; The forces may be replaced by masses. The relat

45、ionship 10 N = 1 kg should be used. Velocities: 5 % of the nominal velocity; Masses: 1 % of the nominal mass; Dimensions: 1 mm of the nominal dimension; Angles: 2 of the nominal angle. NOTE For the purposes of uncertainty measurement, test results are not considered to be adversely affected when the

46、 above tolerances are met. 5 Safety requirements 5.1 Principles of safety requirements 5.1.1 General The safety requirements are based upon the knowledge that kitchen units, bathroom units and domestic storage furniture and their components are likely to cause serious injury only when they are heavy

47、 and fall through a significant distance. This is possible if floor standing units overturn, wall or screen hanging units become detached, or heavy components become detached from units. 5.1.2 Determination of centre of gravity The centre of gravity above the floor (for floor standing units) shall b

48、e measured when installed according to the manufacturers instructions. Levelling devices shall be set at their middle position. Height adjustable components shall be placed in their highest position. The centre of gravity of a component or unit shall be taken as the geometric centre of that unit, ex

49、cept in the case of extension elements, where the geometric centre of the usable volume shall be used. All wall hanging units or top hanging units or components thereof are considered to have their centre of gravity more than 900 mm above the floor. BS EN 14749:2016EN 14749:2016 (E) 10 5.1.3 Determination of total mass The total mass is the mass of the component or unit plus the mass determined according to Table 1, unless the unit or component is conspicuously and durably marked by the manufacturer with a maximu
