Common use of Acceptance conditions Clause in Contracts

Acceptance conditions. The access probe shall not touch live parts. If this requirement is verified by a signal circuit between the probe and live parts, the lamp shall not light. In the case of the test for IPXXB, the jointed test finger may penetrate to its 80 mm length, but the stop face (diameter 50 mm x 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 degrees 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 IPXXD, the access probe may penetrate to its full length, but the stop face shall not fully penetrate through the opening. Table 1 Access probes for the tests for protection of persons against access to hazardous parts Jointed Test Finger Material: metal, except where otherwise specified Linear dimensions in millimeters Tolerances on dimensions without specific tolerance: (a) On angles: 0/-10 seconds; (b) On linear dimensions: (i) up to 25 mm: 0/-0.05 mm: (ii) over 25 mm: ±0.2 mm. Both joints shall permit movement in the same plane and the same direction through an angle of 90° with a 0 to +10° tolerance. Annex 4 Verification of potential equalization 1. Test method using a resistance tester. The resistance tester is connected to the measuring points (typically, electrical chassis and electro conductive enclosure/electrical protection barrier) and the resistance is measured using a resistance tester that meets the specification that follows: (a) Resistance tester: Measurement current at least 0.2 A; (b) Resolution: 0.01 Ω or less; (c) The resistance R shall be less than 0.1 Ω.
