19、ion of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO 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 committe
20、e. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance
21、with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires app
22、roval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 11117 was prepared by Technical Commi
23、ttee ISO/TC 58, Gas cylinders, Subcommittee SC 2, Cylinder fittings. This second edition cancels and replaces the first edition (ISO 11117:1998) which has been technically revised.

24、17:2008(E) ISO 2008 All rights reserved v Introduction This International Standard covers devices intended for the protection of gas cylinder valves, where such protection is required, for example, where the valve is unable to meet the impact test requirements of the relevant valve standard to allow
25、 safe transport, handling and storage without such protection. This International Standard specifies the principal dimensions, requirements for fitment and drop test procedure, to confirm the provision of adequate valve protection, in the event of the occurrence of a cylinder toppling from its base.

27、 cylinders Valve protection caps and valve guards Design, construction and tests 1 Scope This International Standard specifies the requirements for valve protection caps and guards for gas cylinders. This International Standard defines tests for checking the mechanical strength and physical properti
28、es of the valve protection cap or valve guard. This International Standard applies to protection devices for valves used on cylinders for liquefied, dissolved or compressed gases. This International Standard excludes protection devices for cylinders with a water capacity of 5 l or less and cylinders
29、 whereby the protection device is fixed by means of lugs welded or brazed to the cylinder, or is welded or brazed directly to the cylinder. This International Standard does not cover valve protection for breathing apparatus cylinders. This International Standard does not specify all the requirements
30、 that may be necessary to enable the valve protection device to be used for lifting the cylinder. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest

35、onal Standard and which represents the valve of equal or lesser dimensions for which approved guards or protection caps provide suitable protection 4 General requirements 4.1 Cap The cap shall be of adequate strength to protect the valve during handling and transportation. It shall be capable of bei
36、ng securely fixed to the cylinder, either by screwed thread or other suitable means. Provision should be made for assisted fitting or removal of the cap, for example, a hexagonal section. Unless otherwise specified, the cap shall be provided with vent hole(s), e.g. by diametrically opposed vent hole
37、s of 10 mm diameter. Two diametrically opposite vent holes shall be provided, each of them having a minimum diameter of 10 mm. (When the cap has no vent hole, the valve outlet passage of the cylinder shall be plugged to prevent leakage and subsequent pressure build up in the cap.) Caps designed for
38、use with valve dimensions in accordance with ISO 10297, as applicable, shall conform to dimensions given in Figure 1 and preferably Figure 4 where a threaded fixing connection is used. Caps designed for use with valves with dimensions other than those given in ISO 10297 shall be tested with the inte
39、nded largest valve. The cap shall be of such dimensions as not to contact any part of the valve. See Tables 1 and 2. 4.2 Guard The guard shall be of adequate strength to protect the valve during handling and transportation. It shall be fixed so as to prevent easy removal by the end user or dismantli
40、ng under normal service conditions. The design shall permit ready access for valve operation and assembly of operational equipment. When the guard is of a rotating type, it shall be capable of manual orientation. The clearance dimensions of the guard given in Figure 2 are typical for valves designed
41、 in accordance with ISO 10297. The centre of the opening in the guard shall be within 10 mm of the valve outlet axis. The opening shall not extend below the reference plane. Where a threaded fixing connection is used, the preferred thread dimensions are given in Figure 4. Figure 3 gives examples of
42、guards. 4.3 Testing Type testing of the protection devices shall be performed in accordance with the procedure described in Clause 6.
