19、 bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental
20、 and nongovernmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member
21、bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard IS0 5353 was prepared by Technical Committee ISOflC 127, Earth-moving machinery, Subcommittee SC 2, Safety re- quirements and human factors. This

24、of the seat index point (SIP) for any kind of seat designed for earth-moving machinery as defined in IS0 6165, and tractors and machinery for agriculture and forestry as defined in IS0 33390. This provides a uniform method for defining the lo- cation of the SIP in relation to a fixing point on the s
25、eat. The SIP may be determined on a seat by itself or with the seat located in its operating environment on the machine. The SIP is a characteristic of the seat; therefore, it may be specified by the seat manufac- turer. 2 Normative references The following standards contain provisions which, throug
26、h reference in this text, constitute provisions of this International Standard. At the time of publi- cation, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of appl
27、ying the most re- cent editions of the standards indicated below. Members of IEC and IS0 maintain registers of cur- rently valid International Standards.

28、ssification. IS0 61 65:1987, Earth-moving machinery - Basic types - Vocabulary, For the purposes of this International Standard, the following definitions apply. 3.1 seat index point; (SIP): Point on the central vertical plane of the seat as determined by the device shown in figure 1, when installed
29、 in the seat as specified in 5.3. NOTES 1 The SIP is fixed with respect to the machine and does not move with the seat through its adjustment and/or os- cillation range. 2 The SIP as established and defined by this International Standard may be considered, for operator work-place design purposes, to
30、 be equivalent to the intersection on the central vertical plane through the seat centreline of the theoretical pivot axis between a human torso and thighs. 3.2 fixing point: Point specified by the manufac- turer to which the SIP is referenced. See figures 2 and 3 for examples. 4 Multiple machine fu
31、nction seats Some seats are designed to locate and fix an operator to petform more than one function with a given ma- chine. Where a second position of the seat is provided because the machine or tractor has a second set of controls, the SIP of the seat has two locations relative to the machine or t
32、ractor, one for each position, as if there were two seats in the machine or tractor. The first location of the SIP shall be used for those Inter- national Standards appropriate to the first location and set of controls and the second location of the SIP shall be used for those International Standard
33、s appropriate to the second location and set of controls. 1 STD-BSI BS EN IS0 5353-ENGL 1999 D Lb2LibbS 0752284 42T D EN IS0 5353:1998 5 Technical requirements 5.1 Device for seat index point (SIP) determination The device for determining the SIP shall comply with figurel. The mass of the device sha
34、ll be 6 kg f 1 kg. The work surfaces of the device shall be of hardwood (sanded with 200 or finer grit paper or equivalent and polished) or equivalent material with the same performance to provide minimum friction with the muslin cloth in 5.3.1. 5.2 Adjustments when determining the seat index point
35、(SIP) When the relevant adjustments are a part of the seat and its suspension, the seat shall be adjusted ac- cording to the following sequential steps before de- termining the SIP. 5.2.1 Seat adjustment All fore, aft, vertical and angular adjustments shall be placed in their centre position. When n
36、o centre pos- ition is possible, the nearest adjustment that will move the SIP device upward or rearward of centre shall be used. 5.2.2 Suspension system Block the suspension system according to the manu- facturers instruction. If such instruction is not pro- vided, block the suspension system at th
37、e midpoint of its oscillation range. Non-adjustable suspension shall be blocked in the vertical position attained with the weighted device in place. 5.3 Seat index point (SIP) determination The SIP shall be determined by using the device il- lustrated in figure1 and applying the following pro- cedur
38、es. 5.3.1 Seat preparation Allow sufficient time to ensure that the seat reaches a room temperature of 20 “C I 2 OC before starting the measurement procedure. Place the seat on a level surface. Seat a 75 kg f 10 kg person in the seat twice for 1 min periods to flex the seat and back cushions. Al- lo
39、w the seat to remain unloaded for a minimum period of 5 min before starting the measurement procedure. Cover the seat with a single layer of muslin cloth of sufficient size to prevent direct contact and minimize friction between the cushion surfaces and the measurement device. Take care to prevent t
40、he cloth from influencing the positioning of the device. 5.3.2 Device placement Place the SIP device, without additional masses, lat- erally central on the seat cushion pushing against the back cushion (see figure2). Ensure that the device is laterally controlled and level on the seat. Add masses to
41、 bring the total mass of the device from 6 kg f 1 kg to 26 kg f 1 kg; the vertical force centre of the added masses shall be 40 mm in front of the SIP mark on the horizontal section of the device (see figure 1 ). To obtain a good fit between the seat cushion, the back cushion, and the SIP measuring
42、device, alter- nately apply and release a horizontal rearward force of approximately 100 N at the location noted in figure 1, and rock the device from side to side. Add further masses to bring the total mass of the device from 26 kg k 1 kg to 65 kg f 1 kg such that the vertical force centre of the a
43、dditional masses is 40 mm in front of the SIP mark on the horizontal section of the device (see figure 1). NOTE 3 A 75 kg operator approximates the 65 kg weighted device on the seat. Repeat the alternate loading and releasing, and the rocking of the device, checking to make sure the de- vice is late
44、rally central and level on the seat. 5.3.3 Measurement Make measurements on each side of the SIP meas- uring device at points an equal distance from the central vertical plane (see figurez). Average the val- ues. Record within f 1 mm the coordinate dimen- sions of the SIP from the fixing point on th
45、e seat assembly (see figure31 that is defined by the manu- facturer. Some machines have seats which fulfil multiple func- tions, usually by rotating the seat. Functions may in- clude using machine equipment or operating the machine in travel mode. For these cases, it may not be possible readily to c
46、alculate the location of the dif- ferent SIPS relative to the fixing point. In these cases, repeat 5.2 and 5.3 for each of the positions. 2 5.4 Report c) a drawing or sketch of the seat assembly showing the coordinate dimensions between the fixing The test report shall include the following informat
