General 1.1 Scope and object This International Standard specifies details and dimensions of test probes intended to verify the protection provided by enclosures with regard to: protection o

27、f persons against access to hazardous parts inside the enclosure; protection of the equipment inside the enclosure against ingress of solid foreign objects. The object of this International Standard is: to bring together in one publication object probes and access probes currently specified in other

28、 standards, together with any necessary new probes; to guide technical committees in the selection of test probes; to encourage those concerned to specify test probes in accordance with those already specified in this International Standard rather than modify details and dimensions; to limit the fur

29、ther proliferation of types of test probe. 1.2 General recommendations When selecting probes, priority should be given to IP code probes. The use of other probes, particularly probes which are not specified in this International Standard, should be limited to cases where the use of an IP code probe

30、is for some reason impractical. NOTE 1 The selection of a test probe for a particular purpose is the responsibility of the relevant technical committees. NOTE 2 Technical committees wishing to develop new probes or to modify existing probes should submit proposals to technical committee 70 for amend

31、ment of this standard. Application of the probes, test conditions, acceptance conditions and the procedure in case of conflicting test results are the responsibility of the relevant product committee. Certificates based on test probes conforming to the first edition of IEC 61032 should remain valid.

37、to the enclosure or formed by the enclosed equipment suitable to prevent or limit the penetration of the specified test probes are considered as a part of the enclosure, except when they can be removed without the use of a key or tool.
