IEC 63010-2:2017 pdf download.Halogen-free thermoplastic insulated and sheathed flexible cables of rated voltages up to and including 300/300 V
1 Scope
This part of IEC 6301 0 specifies test methods that are particular for cables with insulation and sheath based on halogen-free thermoplastic compounds having rated voltage up to and including 300/300 V for use with small devices and for short connections to desktop electrical appliances where flexibility is of prime importance. General requirements and cable types are specified in IEC 6301 0-1 .

4 General requirements
4.1 Pre-conditioning All the tests shall be carried out not less than 1 6 h after the extrusion of the insulating or sheathing compounds. 4.2 Test temperature Unless otherwise specified, tests shall be carried out at an ambient temperature of (20 ± 5) °C.4.3 Test voltage Unless otherwise specified in the individual clause of this document, the test voltage shall be AC of approximately sine wave form and of frequency between 49 Hz and 61 Hz. The ratio of peak value to r.m.s. value shall be equal to √2 with a tolerance of ±7 %. The values quoted are r.m.s. values. 4.4 Test values Full test conditions (such as temperatures and durations) and full test requirements are not specified in this document; it is intended that they should be specified by the document dealing with the relevant type of cable. Any test requirements that are given in this document may be modified by the relevant cable standard to suit the needs of a particular type of cable.
5 Test methods
5.1 Electrical test methods 5.1 .1 Long term resistance of insulation to DC 5.1 .1 .1 Test sample Carry out the test on a sample of cable of 5 m in length from which all coverings have been removed. Take care to avoid damage to the core(s) during removal of the coverings. 5.1 .1 .2 Procedure Immerse the sample, for the period and at the temperature given in Table 4 of IEC 6301 0-1 :201 7, in an aqueous solution of sodium chloride having a concentration of 1 0 g/l, with a length of about 250 mm at each end of the sample projecting above the solution. Connect the negative pole of a 220 V DC supply to the conductor(s) of the sample and the positive pole to a copper electrode immersed in the solution for the time given in the relevant cable standard. 5.1 .1 .3 Requirement No breakdown of the insulation shall occur during the test and, after the test, the exterior of the insulation shall show no sign of damage. Discoloration of the insulation should be ignored. 5.1 .2 Absence of faults in insulation 5.1 .2.1 General Test all the cable that is in the final stage of manufacture, whether it is in delivery lengths or in manufacturing lengths prior to being cut into delivery lengths. Test all cables with the voltage test in accordance with 5.1 .
