● Detection tool: digital caliper or micrometer.
● Indicate the code for inspection.
● The number of outlet slots is 5 × 2.
● the hole K is not roundness ≤ 0.20mm, with the inner shell D size with the appropriate fit.
● hole hole anastomosis is not allowed to have a clear step, two pieces of flat after no obvious warping, splicing seam ≤ 0.20mm.
● shape no defect or damage, allowing anastomosis in the absence of defects, color is no different normal
● finish up to ▽ 7 or more, but allow for harmless scars and miniatures.
● Metal-free impurities or other debris, containing metal, debris products, must be waste separation.
● no melting marks, no internal pores bright spot. There are stomatal highlights (excluding melting marks) products for foreign goods.
● no flash, burr and excess material. Key parts of the burr ≤ 0.05 mm.
● anti-pressure ≥ 25 kg / square centimeter, no damage.
● feel a strong elasticity, and not brittle.
● Selection of raw materials must meet the requirements of the EU ROHS directive, and has UL yellow card certification and fixed-point supply.
● heat distortion temperature ≥ 120 degrees Celsius, insulation resistance must be ≥ 1000M ohm, flame retardant UL94Vo level / 0.8-3.2mm.
● High voltage test 4KV (AC, DC) / 1 minute without breakdown. (Tester for the Changzhou Instrument Factory CY2674A type.)
● other structures should meet the transformer manufacturing process as the standard.
