27、which is held by UNI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by January 2013, and conflicting national standards shall be withdrawn at the latest by January 2013. Attention is drawn to the p
28、ossibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 1728:2000. The main changes with respect to the previous edition are listed below. Al
29、l test methods for seating used in European Standards for furniture have been collated in one document. The document now contains methods that were previously listed in EN 581-2, Outdoor furniture, EN 1335-3, Office work chair, and EN 15373, Non-domestic seating. A static load test for headrests has
30、 been included. Wherever possible test methods have been simplified and clarified for ease of use. According to the CEN/CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cy
31、prus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the Unit

DIN EN 1728:2014-02 EN 1728:2012 + AC:2013 (E)5 1 Scope This European Standard specifies test methods fo
33、r the determination of strength and durability of the structure of all types of seating without regard to use, materials, design/construction or manufacturing process. This European Standard does not apply to childrens highchairs, table mounted chairs and bath seats which are covered by other Europe
34、an Standards. Test methods for the assessment of ageing, degradation, ergonomics and electrical functions are not included. The test methods are not intended to assess the durability of upholstery materials, such as upholstery filling materials and upholstery covers. This European Standard does not
35、include any requirements. Requirements for different end uses can be found in other Standards. 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 appl
36、ies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 7619-2:2010, Rubber, vulcanized or thermoplastic Determination of indentation hardness Part 2: IRHD pocket meter method 3 Terms and definitions For the purposes of this document, the fo
37、llowing terms and definitions apply. 3.1 structure load bearing parts of furniture such as the frame, seat, back and arm supports and suspension 3.2 leg rest extension of the seat area intended to support the legs of the user Note 1 to entry: A leg rest might or might not be permanently attached to
38、the structure of the item of seating. 3.3 foot rest part intended to support the feet of the user and which assists the user getting on or off an item of seating Note 1 to entry: A foot rest might or might not be permanently attached to the structure of the item of seating. 3.4 work chair chair, wit
39、h or without arm rests, for use by one adult in the office or home office (for example working with a computer), whose upper part, which includes the seat and back, is supported on a single column and can rotate in the horizontal plane and is at least adjustable in height DINEN 1728:2014-02EN 1728:2
40、012 + AC:2013 (E)6 3.5 back rest element that supports the back of the user higher than 100 mm above the seat loading point 3.6 arm rest length distance between vertical lines through the front and rear edges of the arm rest 4 General test conditions 4.1 Preliminary preparation The furniture shall b
41、e tested as delivered. Knock-down furniture shall be assembled according to the instructions supplied. If the instructions allow the furniture to be assembled or combined in different ways, the most adverse combination shall be used for each test. Knock-down fittings shall be tightened before testin
42、g. Further tightening shall not take place unless specifically required by the manufacturer. For seating that is designed to be fixed to the structure of a building, the unit shall be mounted according to the manufacturers instructions to a structure representative of the service installation. This
43、structure shall be sufficiently strong and stiff to eliminate the possibility of it affecting the results of the test. Unless otherwise specified by the manufacturer, the sample for test shall be stored in indoor ambient conditions for at least 24 h immediately prior to testing. The tests shall be c
44、arried out at indoor ambient conditions. However, if during a test the temperature is outside the range 15C to 25C, the maximum and/or minimum temperature shall be recorded in the test report. 4.2 Application of forces The test forces in durability and static load tests shall be applied sufficiently
45、 slowly to ensure that negligible dynamic load is applied. The forces in durability tests shall be applied sufficiently slowly to ensure that kinetic heating does not occur. Unless otherwise stated, static forces shall be maintained for (10 2) s. Unless otherwise stated, durability forces shall be m
46、aintained for (2 1) s. The forces may be replaced by masses. The relationship 10 N = 1 kg shall be used. 4.3 Tolerances Unless otherwise stated, the following tolerances are applicable to the test equipment: Forces: 5 % of the nominal force; Velocities: 5 % of the nominal velocity; Masses: 1 % of th
47、e nominal mass; Dimensions: 1 mm of the nominal dimension; Angles: 2oof the nominal angle. DIN EN 1728:2014-02 EN 1728:2012 + AC:2013 (E)7 The accuracy for the positioning of loading pads and impact plates shall be 5 mm. NOTE For the purposes of uncertainty measurement, test results are not consider
48、ed to be adversely affected when the above tolerances are met. 5 Test equipment and apparatus The equipment shall not inhibit deformation nor cause unnatural deformation of the unit/component, i.e. it shall be able to move so that it can follow the deformation of the unit/component during testing.
