This International Standard specifies details and dimensions of test probes intended to verify the protection provided by enclosures with regard to: - protection of 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 Standard is: a) to bring together in one publication object probes and access probes currently specified in other standards with any new probe required; b) to guide Technical Committees in the selection of test probes; c) to encourage those concerned to specify test probes in accordance with those already specified in this International Standard rather than modify details and dimensions; d) to limit the further proliferation of types of test probe.
