12、O 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 committee. International organizations, gove

13、rnmental 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 with the rules given in the ISO/IEC D

14、irectives, 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 approval by at least 75 % of the member b

18、 objects, water and access1 ScopeThis International Standard applies to degrees of protection (IP code) provided by enclosures of the electrical equipment of road vehicles. It specifies the following:a) Designations and definitions of types and degrees of protection provided by enclosures of electri

19、cal equipment (IP codes) for the: protection of electrical equipment within the enclosure against ingress of foreign objects, including dust (protection against foreign objects); protection of persons against access to hazardous parts inside the enclosure (protection against access); protection of e

20、lectrical equipment inside the enclosure against effects due to ingress of water (protection against water).b) Requirements for each degree of protection.c) Tests to be carried out in order to confirm that the enclosure complies with requirements of the relevant degree of protection.2 Normative refe

26、two code elements have been indicated).Additional and/or supplementary letters may be omitted without substitute.Additional letters following each other directly shall be in alphabetical order.Wherever the degree of protection of a part of the enclosure or the electrical equipment deviates from the

27、degree of protection of the remaining part, both degrees of protection shall be indicated.4.2 Meaning of IP codeTable 1 contains an overview of the IP code elements.2 ISO 2013 All rights reservedBS ISO 20653:2013ISO 20653:2013(E)Table 1 Overview of all IP code elements and meaningElement IP Meaning

34、.5 Degrees of protection against foreign objects and against accessTables 2 and 3 contain short descriptions of the degrees of protection with the relevant requirements.If the same degree of protection (identical code element) for protection against foreign objects and access is required, then both

35、requirements are indicated by the first code element.If different degrees of protection for both protection types are required, then an additional letter shall be used. In this case the first code element only defines the protection against foreign objects and the additional letter indicates the pro

36、tection against access.Additional letters may only be used if: the degree of protection against access is higher than indicated by the first code element, or only the degree of protection against access is to be indicated (first code element substituted by X).The indication of a degree of protection

37、 against access and foreign objects always includes the preceding degrees of protection.Table 2 Degrees of protection against foreign objectsFirst code elementDegree of protectionBrief description Requirements0 not protected None1 foreign objects diameter 50 mmTest probe with diameter 50 mm shall no
