One of the cores shall have the smallest insulation thickness of the relevant types of cord; the other core shall have the largest in The preparation of the punctures in the insulation shall be effected as follows. Preparation of core for spark test equipment check: removal of insulation Preparation of core for spark test equipment check: covering with tape <\/td>\n<\/tr>\n | ||||||
| 51<\/td>\n | The prepared test pieces shall then be passed through the spark test equipment at the highest speed for which the equipment is i… Method to check the recovery time (normative) Solderability test for plain conductors (normative) Solderability test for plain conductors Principle Pre-selection of samples Selection of samples and preparation of test pieces One sample having a length suitable for the bending test described in F.3.2 shall be taken at each of three points in the cord, and the cores in each sample shall be carefully separated from all other components. Each sample of core thus obtained shall be wound, in three turns, on a mandrel, the diameter of which is three times that of the core. From each sample of core which has been straightened out after the third cycle of bending operations, a test piece having a length of about 150 mm shall be taken from that part of the core which has actually been wound. <\/td>\n<\/tr>\n | ||||||
