Testing

GT Rotary Cam Switch,Breaker Control Switch(BCS) and TFV Switch comply with the following standards:

  • IEC 947-3
  • IS 13947-3
  • EN 60947-3

Rotary Cam switch and BCS are type tested at ERDA(Electronics Research and Development Association),Baroda.TFV Switch is type tested at Austrian Research Institute, Vienna.

Inspection:

The following inspections are carried out in different stages of our manufacturing process, they are:

  • Inward inspection
  • Inprocess inspection
  • Final inspection and Testing

Inward Inspection

Inward inspection is classified as follows:

RAW MATERIALS
  • Ferrous & Non-ferrous
    • Dimensions verification
    • Finishing
    • Suppliers test certificate
    • Packing
    • Compositions will be cross verified
  • Plastics
    • Material grade
    • Packing
PLASTIC COMPONENTS
  • Critical dimensions verification as per drawing
  • Visual defects
  • Finishing
  • Packing (component name, part number, grade of the material, etc…)
STAMPING COMPONENTS
  • Critical dimensions verification as per drawing
  • Burr
  • Visual defects- random
  • Finishing
  • Packing (component name, part number, etc…)
FASTENERS
  • Dimensions verification as per standards
  • Visual defects
  • Torque test
  • Finishing

Inprocess Inspection

  • 1st piece inspection
  • Periodical inspection as per sampling plan
  • Self Inspection as per relevant procedure

Final Inspection

  • Visual inspection as per OEP(program number, name plate, technical specification, color of accessories, type of packing etc)

TESTING

ROUTINE TEST
