14、f cylinders manufactured from composite materials and aluminium; addition of an environmental checklist Annex A. Users of this standard, prepared in the field of application of Article 118A of the EC Treaty, should be aware that standards have no formal legal relationship with Directives that may ha

In addition, national legislation in the Member states may contain more stringent requirements than the minimum requirements of a Directive based on Article 118A.

18、16:2010EN 12816:2010 (E) 4 Introduction This European Standard specifies a method for safe handling and disposal of refillable LPG cylinders, of water capacity 0,5 litres up to and including 150 litres, that have been received into filling/maintenance/requalification plants from customers, waste col
19、lection depots, etc. This European Standard calls for the use of substances and procedures that may be injurious to health and/or environment if adequate precautions are not taken. It refers only to technical suitability and does not absolve the user from legal obligations relating to health, safety
20、 and environmental protection at any stage. Protection of the environment is a key political issue in Europe and elsewhere. Protection of the environment is taken in a very broad sense. The standard takes into consideration the total lifecycle aspects of the activities involved in complying with the
21、 standard. These activities include all phases such as scrapping, recycling of materials, etc. It has been assumed in the drafting of this European Standard that execution of its provisions is entrusted to appropriately qualified and experienced people. BS EN 12816:2010EN 12816:2010 (E) 5 1 Scope Th
22、is European Standard specifies methods for the safe gas freeing and disposal of refillable LPG cylinders manufactured from steel, composite materials and aluminium, of water capacity 0,5 litres up to and including 150 litres. This European Standard is applicable to the following: welded and brazed s
23、teel LPG cylinders with a specified minimum wall thickness (see EN 1442 and EN 12807 or equivalent standard); welded steel LPG cylinders without specified minimum wall thickness (see EN 14140 or equivalent standard); welded aluminium LPG cylinders (see EN 13110 or equivalent standard); composite LPG
24、 cylinders (see EN 14427 or equivalent standard). This European Standard is intended to be applied to cylinders complying with ADR (including pi marked cylinders) and also to existing non ADR cylinder populations. 2 Normative references The following referenced documents are indispensable for the ap
25、plication of this European Standard. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

26、riodic inspection of cylinders 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 liquefied petroleum gas LPG mixture of predominantly butane or propane with traces of other hydrocarbon gases classified in accordance with UN number 1965, hydroca
27、rbon gases mixture, liquefied, NOS or UN number 1075, petroleum gases, liquefied NOTE In some countries, UN numbers 1011 and 1978 may also be designated LPG. 3.2 gas free with an LPG concentration in air less than 20 % of the lower explosive limit 3.3 disposal discarding of LPG cylinders in the form
28、 of scrap material after gas freeing 3.4 cylinder disposer organisation responsible for disposal of an LPG cylinder BS EN 12816:2010EN 12816:2010 (E) 6 3.5 purging displacing LPG with a non-flammable gas, steam or water 3.6 evacuation removal of the LPG from the cylinder by the use of a vacuum 4 Gas
29、 freeing of cylinders 4.1 Cylinder disposers shall remove LPG from cylinders by: returning to an LPG storage tank via a suitably designed pump/compressor system, or flaring through a purpose designed flare stack fitted with a flame arrestor as required, or venting through a purpose designed high lev
30、el vent, in a controlled manner, that ensures that the vented gas is diluted to less than 20 % of the lower explosive limit before it reaches ground level, or any potential source of ignition, or a combination of any of these options. For safety and environmental protection reasons the first option
31、is preferable. However it is recommended that, at a minimum, the liquid contents of cylinders should always be returned to an LPG storage tank. 4.2 Equipment used for removal of LPG shall be capable of removing liquid LPG from any cylinder however full. It should also be capable of removing LPG vapo
32、ur so that the internal pressure is reduced to atmospheric. 4.3 Cylinders shall be made gas free by a safe means, for example: evacuation, or purging. NOTE 1 Where water is the purging fluid, waste water should be recycled where possible for further purging applications. NOTE 2 Where possible, the r
33、ecovery of the gas should be maximised in a closed loop system and stored for re-use. 4.4 Any flammable liquids remaining in the cylinder (e.g. oily residues) shall be removed and disposed of in a suitable manner before the cylinder can be considered gas free. 4.5 Cylinders shall be checked to ensur
34、e that they are depressurised and gas free prior to disposal. 4.6 Valves and other fittings shall be: scrapped and recycled, or inspected/reconditioned in accordance with EN 14912 for re-use. 5 Disposal of cylinders 5.1 Disposal shall only take place after a cylinder is made gas free and the cylinde
35、r valve has been removed. 5.2 Cylinders shall be made unserviceable for storing LPG by any of the following methods: BS EN 12816:2010EN 12816:2010 (E) 7 mechanical crushing; mechanical shredding; piercing holes of 50 mm diameter or more, in at least two places; irregular cutting of the neck of the c
36、ylinder; irregular cutting of the body of the cylinder, into two or more pieces. NOTE Noise levels from the above methods should be evaluated and measures put in place to minimise the impact upon the external environment. 5.3 Cylinders made unserviceable in accordance with 5.2 shall be considered as
37、 scrap material for disposal and recycled in order to maximise the re-use of scrap material and minimise the total energy life cycle of the cylinders. The cylinder disposer shall endeavour to minimise wastage of material by selecting the most appropriate scrapping method. NOTE Any coatings on cylind
38、ers may affect recycling methods and should be taken into account. 5.4 Composite cylinders shall be disposed of in accordance with the manufacturers instructions, e.g. the recycling of thermoplastic parts and metallic liners, the grinding of thermoset parts.
