Endorsement notice The text of ISO 11117:2008 has been approved by CEN as EN ISO 11117:2008 without any modification. Introduction This International Standard covers devices intended for the protection of
20、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 safe transport, handling and storage without such protection. This International Standard specifies the principal dimensions, re
21、quirements 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. 4 DIN EN ISO 11117:2009-01 EN ISO 11117:2008 (E) 1 Scope This International Standard specifies the requirements for valve protec
22、tion caps and guards for gas cylinders. This International Standard defines tests for checking the mechanical strength and physical properties of the valve protection cap or valve guard. This International Standard applies to protection devices for valves used on cylinders for liquefied, dissolved o
23、r compressed gases. This International Standard excludes protection devices for cylinders with a water capacity of 5 l or less and cylinders 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 S
24、tandard does not cover valve protection for breathing apparatus cylinders. This International Standard does not specify all the requirements 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

30、. It shall be capable of being 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 dia
31、metrically opposed vent holes 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
32、the cap.) Caps designed for 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 s
33、hall be tested with the intended 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
34、by the end user or dismantling 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
35、 typical for valves designed 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.
36、 Figure 3 gives examples of guards. 4.3 Testing Type testing of the protection devices shall be performed in accordance with the procedure described in Clause 6. 6 DIN EN ISO 11117:2009-01 EN ISO 11117:2008 (E) Dimensions in millimetres Key 1 cap with open top 5 cylinder neck ring 2 closed cap 6 ref
