5.3.20 Knock-out inlets (outlets)intended to be removed by mechanical impact
Test: Inspection and tests according to 5.3.20.1 and 5.3.20.2
5.3.20.1 Knock-out retention For boxes and enclosures having knock-outs accessible after installation, a force of (45 ± 1)N shall be applied to a knock-out for (15 ± 1) s by means of a 6 mm diameter mandrel with a flat end. The force is to be applied without a blow in a direction perpendicular to the plane of the knock-out and at a point most likely to cause movement. The knock-out shall remain in place and the degree of protection of the enclosure shall be unchanged when measured 1 h after the force has been removed. 5.3.20.2 Knock-out removal The knock-outs shall be removed by means of a tool, as stated by the manufacturer. The side edge of a screwdriver may be run along the edge of the knock-out opening once to remove any fragile tabs remaining along the edge. The test is repeated with one box or enclosure which has been conditioned for 5 h ± 10 min in air maintained at the temperature (­20 ± 2)° Immediately following this conditioning, the knock-out is to be removed as above. For a C. box and an enclosure employing multi-stage knock-outs, there shall be no displacement of a larger stage when a smaller stage is removed. After the test there shall be no sharp edges except for knock-out inlets (outlets) for conduits and/or for use with a grommet or a membrane and the box and enclosure shall not be damaged. 5.3.21 Test of cord anchorage

5.3.21.1 For junction box with cable specified by manufacturer the tests have to be performed with the conductors as stated by the manufacturer.
The cable is marked when unloaded so that any displacement relative to the gland can be easily detected. The cable is pulled for a duration of 1 s, 50 times, without jerks in the direction of the axis with the relevant force specified in table 3 At the end of this period the displacement shall not exceed 2 mm. This measurement is to be carried out after unloading the force from the test mandrel. Following the specimen is mounted in the test apparatus for torque test. The cable is marked when unloaded so that any torsion relative to the gland can be easily detected, and then a torque specified in table 4 is applied for 1 min. During test the torsion shall not exceed 45° . 5.3.21.2 For other junction boxes the test is to be performed as followed: A test mandrel equivalent to the minimum value of the anchorage range of the cable gland as declared by the manufacturer or supplier, with a sleeve thickness as specified in table 3 is fixed to the sample. The test mandrel is marked when unloaded so that any displacement relative to the gland can be easily detected. The test mandrel is pulled for a duration of 1 s, 50 times, without jerks in the direction of the axis with the relevant force specified in table 3 At the end of this period the displacement shall not exceed 2 mm. This measurement is to be carried out after unloading the force from the test mandrel. Unless otherwise specified test mandrels shall consist of a metallic rod with an elastomeric sleeving having a hardness of 70 Shore D ± 10 points in accordance with ISO 868, a sleeve thickness as specified in table 3 or table 4. The complete test mandrel shall have a tolerance of ± 0,2 mm for mandrels up to and including 16 mm diameter and ± 0,3 mm for mandrels larger than 16 mm diameter. The shape shall be circular or a profile simulating the outer dimension of the cable as declared by the manufacturer or supplier.

Tests according to 5.3.22.1 and 5.3.22.2 will be performed at specimen which passed through test sequences of test group E and F. During test there should be no deposition of the box at the mounting surface which impairs isolating characteristics. The test is performed under consideration of requirements of 5.2.5. 6.3.5.1 A force of 40N is gradually applied for 30 min in each direction parallel to the mounting surface.
6.3.5.2 A force of 40N is gradually applied for 30 min without jerks, in a direction perpendicular to the mounting surfaces.

Mechanical strength of adhesive Tests according to 6.3.5.1 and 6.3.5.2 will be performed at specimen which passed through test sequences of test group E and F. During test there should be no deposition of the box at the mounting surface which impairs isolating characteristics. The test is performed under consideration of requirements of 6.2.5. 6.3.5.1 A force of 40N is gradually applied for 30 min in each direction parallel to the mounting surface. 6.3.5.2 A force of 40N is gradually applied for 30 min without jerks, in a direction perpendicular to the mounting surfaces. 6.3.6 Measurement of clearances and creepage distances
Clearances and creepage distances shall be measured according to IEC 60664-1. 6.3.7 Dielectric strength
The impulse withstand test shall be carried out with a voltage having a 1,2/50 µs waveform according to IEC 60060-1 with three impulses of each polarity and an interval of at least 1 s between pulses. The output impedance of the impulse generator should not be higher than 500 . The test voltage shall comply with the rated impulse voltage under consideration of IEC 60664-1. b) r.m.s. withstand voltage test
The voltage proof test shall be performed by applying a r.m.s. withstand voltage (50/60 Hz) with a rmsvalue of 2000V + 4 times rated voltage. The test duration shall be 1 min. 6.3.8 Resistance to corrosion
Ferrous parts of boxes and enclosures shall be adequately protected against rusting. Compliance is checked by the following test: All grease is removed from the parts to be tested, by immersion in a degreasing agent for (10 ±1) min. The parts are then immersed for (10 ±1) min in a 10% solution of ammonium chloride in water at a temperature of (20 ± 5) °C.
Without drying, but after shaking off any drops, the parts, are placed for (10 ±1) min in a box containing air saturated with moisture to a level of 91% to 95 % at a temperature of (20 ± 5) °C. After the parts have been dried for (10 ±1) min in a heating cabinet at a temperature of (100 ± 5) °C, their surface shall show no sign of rust.
