Introduction This standard provides guidance on the operation of vehicles that use natural gas as a fuel, and gives recommendations of good practice for users, parking facilities, refuelling stations and workshops appropriate for NGVs, whether or not the gas system is to be worked on. This stand
18、ard is mainly directed at: * Vehicle Park Owner /Operator / User * NGV Dealer / Owner / User 1 1.1 1.2 1.3 * Workshop Operators Scope This standard gives recommendations for the operation of vehicles fuelled with natural gas and operating at a fuel system pressure not exceeding 20 MPa (200bar) at 15
19、 OC. This standard may be applied to higher system pressures, but due regard should then be given to safety aspects such as, ventilation rates, hazardous area requirements and other aspects associated with those higher pressures. It applies to vehicles conforming to ISO/DIS 15501-1 : 2000 and ISO/DI
20、S 15501 -2 : 2000 and to refuelling stations conforming to prEN 13638:1999.

27、or or dealer responsible for the sale or maintenance of the ve h icle 4.1 4.2 4.2.1 4.2.2 4.2.3 4.3 4.3.1 Parking Where NGVs are parked in enclosed areas, there should be suitable ventilation to prevent the hazardous accumulation of gas. Documents / Information The owner of the NGV should familiaris
28、e himself with documentation provided by the supplier of the vehicle on the safe operation of the NGV which should cover the safety related properties of natural gas. The owner should keep the operational information up dated with available documentation as supplied. It is recommended that the infor
29、mation be kept in the NGV to ensure it is available when necessary. The owner should ensure that natural gas notices on the vehicle are kept clear and legible. Operation The owner should ensure that the vehicle is maintained and operated in accordance with the vehicle manufacturer/converter specific
30、ations and instruction manual. _ STDOBSI BS EN L3Y23-ENGL 2000 Lb24bb7 088537Li bA5 Page 6 EN 13423 : 2000 4.3.2 4.3.3 4.4 4.4.1 4.4.2 4.5 4.6 4.6.1 4.6.2 4.7 4.8 The gas containers shall be examined and revalidated at the prescribed intervals as given by the manufacturer/converter in accordance wit
31、h local regulations. The owner should ensure that any work on the gas system is only carried out by a competent person. Refuelling Before refuelling, the driver should examine the vehicle and station notices to ensure that the vehicle is compatible with the following Station parameters:- * Gas quali
32、ty designation. * Refuelling nozzle type. * Filling pressure (at 15C). The refuelling equipment should only be used for filling gas containers and gas fuel systems which meet the designed operating temperature and pressure of the refuelling facility. Accidents Following an accident involving damage
33、to the vehicle, the integrity of the gas system should be checked by a competent person. Vehicle disposal - scrapping The owner should ensure that the gas system is vented by a competent person before the vehicle is disposed of. The owner should inform the vehicle disposal agency if gas containers a
34、re still present. Vehicle disposal - resale When the vehicle is sold as an NGV, the relevant NGV documents, in particular the gas container validation certificate, should be transferred with the vehicle. (If the natural gas equipment is removed before transfer this does not apply) Special considerat
35、ions When the NGV is to be transported by road, rail or ferry, or a tunnel is to be used, the driver should check whether there are any specific restrictions. He should advise those responsible for transporting the NGV of all the fuels on board the vehicle. , STD-BSI BS EN 13423-ENGL 2000 lb24bb9 08
36、85395 511 Page 7 EN 13423 : 2000 5 Workshop operations 5.1 Safety 5.1.1 A written procedure should be provided to cover NGV operations, safety, and emergencies. 5.1.2 Precautions should be taken to prevent the uncontrolled release of gas when work is being undertaken on a vehicle. 5.1.3 Adequate ven
37、tilation should be provided to prevent the hazardous accumulation of any released gas. Ventilation at high level should be adequate to prevent the accumulation of gas in roof spaces. 5.2 Competence of operatives Persons involved with natural gas vehicle systems should be appropriately trained includ
38、ing a basic knowledge of natural gas. It is recommended that training be as follows: - Operatives working in the vicinity of NGVs. Should be informed of the presence of NGVs and the precautions to be taken. - Operatives working on NGVs but not on the gas systems. Should be aware of the differences b
39、etween gas and liquid fuelled vehicles, and be able to recognise the natural gas system components. - Operatives and their supervisors servicing and maintaining gas systems. Should be competent to repair, maintain and commission NGVs. - Operatives installing gas systems. Should be competent to insta
40、ll all aspects of the equipment. 5.3 Gas system work 5.3.1 It is essential that where there is a suspected gas leak on a vehicle, no potential source of ignition should exist within 3 metres of the vehicle unless the gas containers on the vehicle have been isolated. Operatives working on any part of
41、 the gas system should ensure that the container(s) are isolated; unless required for that operation; and there is no potential source of ignition within 1 metre of that part of the gas system.

42、.5.2 5.6 Any gas system components replaced on the vehicle should be to the original specification and ensure compliance with ISO/DIS 15501 -1 :2000 and ISO/DIS 15501 -2:2000 After any work on the gas-carrying components and pipework, it is essential that the system be inspected for gas leaks using
43、an appropriate gas detection method covering the range of operating pressures, ensuring all components are checked. Depressurisation of the gas containers should be carried out by recovering the gas. If recovery is not feasible, the venting of the gas containers should be to the open air. Gas may on
44、ly be vented at high level and away from any potential sources of ignition. Depressurisation of the gas components and pipework (gas containers isolated) may involve the release of a minimal amount of gas and requires adequate ventilation. Non gas system work Non-gas system work should not affect th
45、e integrity of the gas system. Operatives should seek the advice of a competent person before undertaking repair work. Container exchange procedures When a gas container is removed from the vehicle, it may only be replaced with a container designed and manufactured to a standard suitable for NGV use
46、. The replacement container should be installed in a manner that ensures conformity with ISO/DIS 15501 -1 :2000 and ISO/DIS 15501 -212000 It is essential that the competent person undertaking the installation updates the appropriate vehicle documents and/or vehicle data plates with the new container
47、 details. Container disposal Containers which have been damaged or which have been removed from vehicles being scrapped should be returned to an approved revalidator in accordance with ISO/FDIS 1 1439:2000 STD-BSI ES EN 13423-ENGL 2000 Lb24bbS 0885377 374 Page 9 EN 13423 : 2000 5.7 Special operation
48、s 5.7.1 Where hot work (such as baking the vehicle in a paint-curing oven) is involved, the workshop should observe all the relevant procedures and precautions including those of the vehicle supplier/converter. 5.7.2 Where a vehicle has been involved in an accident the gas containers may have been d
49、amaged. These should be inspected and tested by a revalidator BS EN 13423:ZOOO BSI 389 Chiswick High Road London w4 4AL BSI - British Standards Institution BSI is the independent national body responsible for preparing British Standards.
