DIN EN 16119:2013-05 EN 16119:2013 (E) 4 Introduction This European Standard calls for the use of subst
20、ances and procedures that may be injurious to health and/or the environment if adequate precautions are not taken. It refers only to technical suitability and does not absolve the user from legal obligations at any stage. Protection of the environment is a key political issue in Europe and elsewhere
21、. Protection of the environment is taken in a very broad sense. What is meant is the total life cycle aspects of, e.g., a product on the environment, including expenditure of energy and during all phases from mining of raw materials, fabrication, packaging, distribution, use, scrapping, recycling of
22、 materials, etc. NOTE Annex C indicates the clauses in this European Standard that address environmental issues. Provisions need to be restricted to a general guidance. Limit values are specified in national laws. It is recommended that manufacturers develop an environmental management policy. For g
23、uidance, see the EN ISO 14000 series. It has been assumed in the drafting of this European Standard that the execution of its provisions is entrusted to appropriately qualified and experienced people. All pressures are gauge pressures unless otherwise stated. This European Standard requires measurem
24、ent of material properties, dimensions and pressures. All such measurements are subject to a degree of uncertainty due to tolerances in measuring equipment etc. It may be beneficial to refer to the leaflet “measurement uncertainty leaflet SP INFO 2000 27 3.

25、 Scope This European Standard specifies the design, testing and marking requirements for caps and plugs used to form a pressure tight seal with liquefied petroleum gas (LPG) cylinder valves and pressure vessel valves. Sealing caps and plugs provide an additional seal for self-closing and manually op
26、erated valves. Dust caps or plugs and tamper evident seals that do not form an additional seal as part of their design are excluded from the scope of this European Standard. Cylinder valve caps and plugs may be used with valves for liquid and vapour manufactured in accordance with EN ISO 14245 and E
27、N ISO 15995. Pressure vessel valve caps and plugs may be used with valves for liquid and vapour manufactured in accordance with EN 13175. Occasional liquid withdrawal valve caps and plugs are excluded from the scope of this European Standard. Reusable and single use sealing caps and plugs are includ
28、ed in this European Standard. This European Standard does not exclude the use of other designs that provide an equivalent level of safety. NOTE The term “pressure vessel” does not include LPG tank vehicles, also called “road tankers”, in CEN/TC 286 standards. 2 Normative references The following doc
