19、tion For the purposes of this standard, the following definition applies. approved workshop tachograph centre that has been approved by a competent authority appointed by the relevant national authority (see foreword) Amdt 2 SANS 10241:2008 Edition 1.2 4 Part l Introductory notes 4 Deleted Part ll C
20、onditions relating to premises and equipment 5 Approved workshops for recording equipment (tachograph centres) shall meet certain minimum requirements in respect of equipment and availability of facilities to ensure that the work for which approval is granted may be completed in an efficient and com
21、petent manner. 6 Premises 6.1 The tachograph centre shall have a potential for carrying out final installation, inspection, calibration and repair of tachograph recording equipment on 2 000 vehicles per annum (As a general rule, the provision of two commercial vehicle work bays should be adequate fo
22、r this purpose if they are used exclusively for tachograph work.); provided that in certain circumstances, i.e. in areas of low vehicle density, where no alternative facilities exist, a tachograph centre may offer facilities for an annual throughput of less than 2 000 vehicles. 6.2 The tachograph ce
23、ntre shall provide off-road parking facilities for at least two commercial vehicles with easy access. 6.3 Work bays used for tachograph work shall be capable of accepting vehicles up to 4,3 m high, 12,5 m long and 2,6 m wide. (Vehicles of greater dimensions which require service may only be dealt wi
24、th at centres where suitable facilities exist.) NOTE Double-decker buses can be 4,65 m high. 6.4 Undercover facilities for viewing and working on the underside of vehicles shall be provided. These may be in the form of a suitable pit, hoist or lift. Commercial vehicle jacks are unacceptable. Where t
25、here is a pit, it shall be at least 5 m in length. In every other case, provision shall be made for the vehicle to be raised at least 1 m from floor level with at least 4,5 m headroom above the platform on which the vehicle will stand. 6.5 A clean workshop area incorporating a work bench shall be se
26、t aside adjacent to the tachograph work bays where adaptor gearbox assembly and repair work may be undertaken when required. The equipment used for calibrating tachograph head units shall also be located in this area. 6.6 Suitable arrangements shall be made for the safe custody by the centre of reco
27、rds, installation plaques, plaque holders and sealing pliers and punches at all times. A lockable steel cabinet or safe is a minimum requirement for the protection of these items when not in use. 6.7 There shall be sufficient storage facilities for essential items of equipment and spares, for exampl
28、e, drive cables and adaptor gearboxes. SANS 10241:2008 Edition 1.2 5 7 Equipment and facilities 7.1 The following shall be provided from the list of equipment and facilities approved by the relevant authority: Amdt 2 7.1.1 Equipment a) Tachograph roller test rig, for vehicle calibration. NOTE SANS 1
29、558 allows for calibration and testing using a straight and level surface of 1 km at a speed of 50 5 km/h. The tachograph roller test rig provides the means of simulating these conditions in the workshop. To carry out such a test without this equipment would entail the exclusive use of a straight an
30、d level testing ground, a r/min distance counter and an accurate vehicle speed indicator other than the instrument under test. However, the relevant national authority (see foreword) may approve as an alternative, any arrangements which in its view fully and efficiently meet the appropriate requirem
31、ents set out in this standard. Amdt 2 b) Tachograph instrument portable drive test unit, suitable for use on the work bench and in the cab of the vehicle. c) Clock tester, to test the accuracy of the tachograph time clock. d) Optical record sheet (chart) analyser, which is a magnifying device for ch
32、art analysis and verification of recordings made. 7.1.2 Slow-speed calibration facilities (20 m track) (see 9.3(d) 7.2 The following shall also be provided: e) Sealing pliers and punches, incorporating the identification mark allocated to the centre by the relevant national authority (see foreword)
33、and a supply of appropriate seals (see appendix D). Amdt 2 f) Tyre pressure gauge. g) Compressor, capable of supplying air at pressure up to 900 kPa. h) Adequate specialist tools, in accordance with the recommendations of the tachograph manufacturers concerned. 7.3 The items of equipment referred to
34、 in paragraphs 7.1(a), (b) and (c) above shall be recalibrated at least every 12 months and a current calibration certificate shall be held by the centre. The certificate shall indicate that the accuracy of the equipment is within the tolerances laid down in this standard (paragraph 9.9) for such eq
35、uipment. Part lll Conditions relating to the testing of recording equipment 8 Conditions relating to vehicles 8.1 Any measurement of recording or visual errors in recording equipment, on installation or during use, shall only be undertaken in the following circumstances: a) The vehicle shall be unla
36、den and in normal operating condition. b) The tyres fitted to the vehicle shall comply with the relevant road traffic regulations. SANS 10241:2008 Edition 1.2 6 c) The tyre pressures should be in accordance with the tyre manufacturers recommendations, for the A rating per axle. 9 Testing procedure 9
37、.1 All tachograph visual and recording equipment shall be checked both on initial installation and subsequently after any repair operation conducted by the centre which has, or in the opinion of that centre may have, altered materially the characteristic coefficient (w) of the vehicle (w is the spee
38、dometer drive pinion revolutions per kilometre). This check shall also be carried out where a vehicle is presented for the annual roadworthiness test. NOTE The work involved in checking is essentially the same in all these cases. The intention of the check is to ensure that the equipment is of a typ
39、e which has been approved by the relevant authority, and that it functions with overall visual and recording errors which are not outside the limits of accuracy laid down in SANS 1558. The check may be carried out before sealing the connections to the tachograph head, adaptor/two-speed unit and the
40、gearbox drive output at installation. Amdt 2 For periodic inspections, this procedure will involve the breaking of seals. 9.2 The centre shall check whether the equipment (on-board computers excluded) is of a type which has received approval from the relevant authority. Amdt 2 a) Tachograph head: En
41、sure that a descriptive label is satisfactorily displayed on the equipment, and that it contains the correct information (paragraph 9.7). The descriptive label should be built into the equipment and must be visible when installed or easily accessible inside the case. b) Record sheets (tachograph cha
42、rts): Check whether the information printed on the chart(s) meets the specification laid down (paragraph 9.8) and whether the chart is compatible with the tachograph head for the purpose of conducting the test. 9.3 The centre shall check whether the error of the visual and recording instrument lies
43、within the limits of accuracy for bench testing laid down in paragraph 9.9 and whether the overall error in the complete installation (including the adaptor gearbox) is within the limits specified in paragraph 9.6 (on-board computers excluded). a) Tachograph head calibration: Any fault detected duri
44、ng the following procedure shall be rectified and a fresh test chart produced before the tachograph head is resealed. i) Remove the tachograph drive cable from the output of the adaptor gearbox (if installed), or if appropriate from the output of the two-speed unit in instances when a two-speed axle
45、 is fitted to the vehicle, breaking the seals if necessary. ii) Check the tachograph drive cable for excessive rotational resistance and rectify if necessary. iii) Connect a tachograph instrument portable drive test unit to the tachograph using a suitable length of cable and adaptors to enable both
46、the tachograph and driving unit speed display to be clearly read from within the cab of the vehicle, or remove the tachograph and test it on a test bench. iv) Ensure that the power supply is connected and that the clock is functioning. v) Insert a new drivers chart in the tachograph, after marking t
47、he following information in convenient positions on the chart: chart identification, i.e. test chart testers name vehicle registration number tachograph make and serial number date of test SANS 10241:2008 Edition 1.2 7 distance recorder (odometer) reading at start of test At the end of the test mark
48、 on the chart: Distance recorder (odometer) reading at end of test; and Distance covered during test. vi) Ensure that the chart position and the time indicated by the clock coincide. vii) Close the tachograph case, and lock with the main key or driver 1 key, if applicable. viii) Check that the tacho
49、graph scale illumination is satisfactory. ix) Switch on the portable driving unit and steadily increase the units speed to full scale deflection on the tachograph speed scale. Compare the indicated speeds of the unit with those indicated by the tachograph speed pointer at several speeds. NOTE With the tachograph installed, speed readings should be free from oscillation, and easily discernible. x) Decrease the driving speed rapidly to zero. This enables the motion of the speed stylus relative to the record sheet to be investigated. Rapid speed re
