Description
IEC 60112 Tracking Index Test Apparatus for CTI & PTI Evaluation | Precision Flammability Testing Equipment for Electrical Insulation Safety
Product introduction

Hey, for those labs where safety is top priority, HongCe came up with this Tracking Index Tester. It checks if solid materials can stop electrical leaks when things get dirty or wet. It has steady controls, drips liquid just right, and is built to last.

If you're in manufacturing, testing, or signing off on products, this tester helps make sure insulation follows IEC 60112 standards, along with similar guidelines . Use it daily!

International reference standards
  • IEC 60112:2020 – Method for the determination of the proof and the comparative tracking indices of solid insulating materials
  • Clause 5: Test apparatus and electrode configuration
  • Clause 6: Test solutions and contamination conditions
  • Clause 7: Test procedure for CTI determination
  • Clause 8: PTI verification method
  • GB/T 4207 – Chinese equivalent to IEC 60112 (CTI/PTI determination)
  • UL 746A – Polymeric materials short-term property evaluations (tracking resistance reference)
  • ASTM D3638 – Tracking resistance of insulating materials (reference method)
Proof tracking index (PTI)

Where, in IEC standards for material or for electrical equipment specifications, or in other standards, a proof test only is required, 50 drop tests shall be made in accordance with Clause 8 but at the single voltage specified. The required number of specimens shall withstand the test period up to at least 25 s after the fiftieth drop has fallen without tracking failure, and without a persistent flame occurring.

Operation of the over-current device by air arcs does not constitute a tracking failure.

The proof voltage shall be an integer multiple of 25 V.

Comparative tracking index (CTI)

Determination of the comparative tracking index requires the determination of the maximum voltage at which five specimens withstand the test period for 50 drops without failure and whether, at a voltage of 25 V lower than the maximum 50 drop figure, the specimen withstands 1 00 drops. If this is not the case, the maximum 1 00 drop withstand voltage has to be determined.

FAQ
Q1: What’s the difference between CTI and PTI?
CTI measures the highest voltage at which a material resists tracking over 50 drops. PTI verifies performance at a fixed voltage level. Both are critical for safety classification.
Q2: Can the voltage range be customized?
Yes. As a direct manufacturer, HongCe can tailor voltage ranges and power specs to your lab standards.
Q3: Is the system suitable for third-party labs and certification bodies?
Absolutely. The apparatus is widely used in compliance labs, R&D centers, and QC departments.
Q4: How often should the equipment be calibrated?
We recommend annual calibration or per your lab’s ISO/IEC 17025 procedures.
Q5: Do you provide test solution preparation guidance?
Yes, we provide SOPs and training for preparing standard IEC test solutions.
