IEC60529
12.3 Acceptance conditions
The protection is satisfactory if adequate clearance is kept between the access probe and hazardous parts.
For the test of first characteristic numeral 1 , the access probe 50 mm diameter shall not completely pass through the opening.
For the test of first characteristic numeral 2, the jointed test finger may penetrate to its 80 mm length, but the stop face ( 50 mm 20 mm) shall not pass through the opening. Starting from the straight position, both joints of the test finger shall be successively bent through an
angle of up to 90° with respect to the axis of the adjoining section of the finger and shall be placed in every possible position.
See annex A for further clarification. Ingress Protection Test Equipment
15.3 Acceptance conditions
The protection is satisfactory if adequate clearance is kept between the access probe and hazardous parts.
In the case of the test for the additional letter B, the jointed test finger may penetrate to its 80 mm length, but the stop face (∅ 50 mm × 20 mm) shall not pass through the opening. Ingress Protection Test Equipment
Starting from the straight position, both joints of the test finger shall be successively bent through an angle of up to 90° with respect to the axis of the adjoining section of the finger and shall be placed in every possible position.
In case of the tests for the additional letters C and D, the access probe may penetrate to its full length, but the stop face shall not fully penetrate through the opening. See annex A for further clarification. Ingress Protection Test Equipment
Conditions for verification of adequate clearance are identical with those given in 12.3.1 , 12.3.2 and 12.3.3.
Application: This probe is intended to verify the basic protection against access to hazardous parts. It is also used to verify the protection against access with a finger.
Test sample: Easily accessible enclosure live parts or mechanical parts.
Feature: This test finger probe consists of dito, finger, base and insulated handle which simulates the characteristics of the human hand. It has two movable joints, which can be curved at 90°. Customizable: it can be used for anti-electric shock test when equipped with pluggable banana plugs and amphenol connector at the end of the handle , or used for enclosure protection test when open threaded hole of M6 at the end of the handle (connected with pull and push dynamometer).
